Blood pressure during pregnancy normal range

Preeclampsia and High Blood Pressure During Pregnancy

Blood pressure is the force of blood pushing against the walls of blood vessels called arteries. The arteries bring blood from the heart to your lungs, where it picks up oxygen and then moves to your organs and tissues. The organs and tissues use the oxygen to power their activities. Blood vessels called veins return the blood to the heart.
High blood pressure (also called hypertension) can lead to health problems at any time in life. High blood pressure usually does not cause symptoms. During pregnancy, severe or uncontrolled high blood pressure can cause problems for you and your fetus.
Some women have high blood pressure before they get pregnant. Others develop it for the first time during pregnancy. A serious high blood pressure disorder called preeclampsia can also happen during pregnancy or soon after childbirth.
A blood pressure reading has two numbers separated by a slash. A blood pressure reading of 110/80 mm Hg, for example, is referred to as “110 over 80.” The first number is the pressure against the artery walls when the heart contracts. This is called the systolic blood pressure. The second number is the pressure against the artery walls when the heart relaxes between contractions. This is called the diastolic blood pressure.
- Normal: Less than 120/80 mm Hg
- Elevated: Systolic between 120 and 129 mm Hg and diastolic less than 80 mm Hg
- Stage 1 hypertension: Systolic between 130 and 139 mm Hg or diastolic between 80 and 89 mm Hg
- Stage 2 hypertension: Systolic at least 140 mm Hg or diastolic at least 90 mm Hg
Your obstetrician–gynecologist (ob-gyn) should check your blood pressure at each prenatal care visit. Blood pressure changes often during the day. If you have one high reading, another reading may be taken later during your office visit.

Chronic hypertension is high blood pressure that a woman has before getting pregnant or that develops in the first half of pregnancy (before 20 weeks of pregnancy). If you were taking blood pressure medication before you got pregnant—even if your blood pressure is currently normal—you have been diagnosed with chronic hypertension.
When you are pregnant, your body makes more blood to support the fetus’s growth. If blood pressure goes up during pregnancy, it can place extra stress on your heart and kidneys. This can lead to heart disease, kidney disease, and stroke. High blood pressure during pregnancy also increases the risk of preeclampsia, preterm birth, placental abruption, and cesarean birth.
High blood pressure may reduce blood flow to the placenta. As a result, the fetus may not get enough of the nutrients and oxygen needed to grow.
In the first half of pregnancy, blood pressure normally goes down. If your hypertension is mild, your blood pressure may stay that way or even return to normal during pregnancy. But if your blood pressure is 140/90 mm Hg or higher, your ob-gyn may recommend that you start or continue taking blood pressure medication during pregnancy.
Your blood pressure should be checked at every prenatal care visit. You may also need to monitor your blood pressure at home. Ultrasound exams may be done throughout pregnancy to track the growth of the fetus. If growth problems are suspected, you may have other tests that monitor the health of the fetus. This testing usually begins in the third trimester of pregnancy.
If your condition remains stable, delivery 1 to 3 weeks before your due date (about 37 weeks to 39 weeks of pregnancy) generally is recommended. If you or the fetus develop complications, delivery may be needed even earlier.
After delivery, you will need to keep monitoring your blood pressure at home for 1 to 2 weeks. Blood pressure often goes up in the weeks after childbirth. You may need to resume taking medication, or your medication dosage may need to be adjusted.
Talk with your ob-gyn about blood pressure medications that are safe to take if you plan to breastfeed. Do not stop any medications without talking with your ob-gyn.

You have gestational hypertension when:
- You have a systolic blood pressure of 140 mm Hg or higher and/or a diastolic blood pressure of 90 mm Hg or higher.
- The high blood pressure first happens after 20 weeks of pregnancy.
- You had normal blood pressure before pregnancy.
Most women with gestational hypertension have only a small increase in blood pressure. But some women develop severe hypertension (defined as systolic blood pressure of 160 mm Hg or higher and/or diastolic blood pressure of 110 mm Hg or higher). These women are at risk of very serious complications.
All women with gestational hypertension are monitored often (usually weekly) for signs of preeclampsia and to make sure that their blood pressure does not go too high.
Although gestational hypertension usually goes away after childbirth, it may increase the risk of developing high blood pressure in the future. If you had gestational hypertension, keep this risk in mind as you take care of your health. Healthy eating, weight loss, and regular exercise may help prevent high blood pressure in the future.

Preeclampsia is a serious disorder that can affect all the organs in your body. It usually develops after 20 weeks of pregnancy, often in the third trimester. When it develops before 34 weeks of pregnancy, it is called early-onset preeclampsia. It can also develop in the weeks after childbirth.
It is not clear why some women develop preeclampsia. Doctors refer to "high risk" and "moderate risk" of preeclampsia.
Factors that may put you in the “high risk” category include
- preeclampsia in a past pregnancy
- carrying more than one fetus (twins, triplets, or more)
- chronic hypertension
- kidney disease
- diabetes mellitus
- autoimmune conditions, such as lupus (systemic lupus erythematosus or SLE)
- having multiple moderate risk factors (see below)
Factors that may put you in the “moderate risk” category include
- being pregnant for the first time
- being pregnant more than 10 years after your previous pregnancy
- body mass index (BMI) over 30
- family history of preeclampsia (mother or sister)
- being age 35 or older
- complications in previous pregnancies, such as having a baby with a low birth weight
- in vitro fertilization (IVF)
- Black race (because of racism and inequities that increase risk of illness)
- lower income (because of inequities that increase risk of illness)
- Preeclampsia can lead to a condition that causes seizures and stroke.
- Preeclampsia can cause HELLP syndrome. HELLP stands for hemolysis, elevated liver enzymes, and low platelet count. HELLP syndrome damages or destroys red blood cells and interferes with blood clotting. It can also cause chest pain, abdominal pain, and bleeding in the liver. HELLP syndrome is a medical emergency. Women can die from HELLP syndrome. They can also have lifelong health problems from the condition.
For women with preeclampsia, early delivery may be needed in some cases. Preterm babies have an increased risk of problems with breathing, eating, staying warm, hearing, and vision. Some preterm complications last a lifetime and require ongoing medical care.
Women who have had preeclampsia—especially those whose babies were born preterm—have an increased risk later in life of kidney disease, heart attack, stroke, and high blood pressure. Also, having preeclampsia once increases the risk of having it again in a future pregnancy.
Preeclampsia can develop quietly without you being aware of it. Symptoms can include
- swelling of face or hands
- headache that will not go away
- seeing spots or changes in eyesight
- pain in the upper abdomen or shoulder
- nausea and vomiting (in the second half of pregnancy)
- sudden weight gain
- difficulty breathing
If you have any of these symptoms, especially if they develop in the second half of pregnancy, call your ob-gyn right away.
A woman with preeclampsia whose condition is worsening will develop “severe features.” Severe features include
- low number of platelets in the blood
- abnormal kidney or liver function
- pain in the upper abdomen
- changes in vision
- fluid in the lungs
- severe headache
- systolic pressure of 160 mm Hg or higher or diastolic pressure of 110 mm Hg or higher
A high blood pressure reading may be the first sign of preeclampsia. If your blood pressure reading is high, it may be checked again to confirm the results. You may have a urine test to check for protein. You may also have tests to check how your liver and kidneys are working and to measure the number of platelets in your blood.
You and your ob-gyn should talk about how your condition will be managed. The goal is to limit complications for you and to deliver the healthiest baby possible.
Women who have gestational hypertension or preeclampsia without severe features may be treated in a hospital or as an outpatient. Being an outpatient means you can stay at home with close monitoring by your ob-gyn. You may need to keep track of your fetus’s movement by doing a daily kick count. You may also need to measure your blood pressure at home. Visits to your ob-gyn may be once or twice a week.
At 37 weeks of pregnancy, you and your ob-gyn may talk about delivery. Labor may be induced (started with medications). If test results show that the fetus is not doing well, you may need to have the baby earlier. Women with preeclampsia can have vaginal deliveries, but if there are problems during labor, cesarean birth may be needed.
If you have preeclampsia with severe features, you may be treated in the hospital. If you are at least 34 weeks pregnant, you and your ob-gyn may talk about having your baby as soon as your condition is stable.
If you are less than 34 weeks pregnant and your condition is stable, it may be possible to wait to deliver your baby. Delaying delivery for just a few days may be helpful in some cases. It allows time to give corticosteroids, which can help the fetus’s lungs mature. Delaying can also give you time to take medications to reduce your blood pressure and help prevent seizures. If your health or the fetus’s health worsens, you and your ob-gyn should discuss immediate delivery.
Read Preterm Labor and Birth or Extremely Preterm Birth to learn more.
Prevention involves identifying whether you have risk factors for preeclampsia and taking steps to address them.
Low-dose aspirin may reduce the risk of preeclampsia in some women. Your ob-gyn may recommend that you take low-dose aspirin if
Low-dose aspirin may also be considered if you are Black or if you have a low income, even if you have no other risk factors.
Talk with your ob-gyn about whether you should take aspirin. Do not start taking aspirin on your own without talking with your ob-gyn.
If you have high blood pressure and want to get pregnant, see your ob-gyn for a check-up. Your ob-gyn will want to know if your high blood pressure is under control and if it has affected your health.
You may have tests to check how your heart and kidneys are working. Your medications should be reviewed to see if you need to switch to others that are safer during pregnancy. You should also talk about the signs and symptoms of preeclampsia.

Normal blood pressure in pregnancy: Levels and management

During pregnancy, a person’s blood pressure should stay within the normal range. Very high or low blood pressure requires medical attention.

According to the American Heart Association (AHA), a healthy person should have a blood pressure reading of less than 120/80 millimeters of mercury (mm HG).

The top number, or systolic, measures blood pressure when the heart contracts. The lower number, or diastolic, measures the blood pressure when the heart is between beats.

Keep reading for more information on blood pressure during pregnancy and steps a pregnant woman can take to keep their blood pressure under control.

Share on PinterestA pregnant woman should monitor their blood pressure during pregnancy to ensure it stays within the normal range.

The American College of Obstetricians and Gynecologists (ACOG) state that a pregnant woman’s blood pressure should also be within the healthy range of less than 120/80 mm Hg.

If blood pressure readings are higher, a pregnant woman may have elevated or high blood pressure. If high blood pressure occurs during pregnancy, it may indicate serious complications such as preeclampsia.

It is important to track and manage blood pressure throughout pregnancy.

Blood pressure is the amount of pressure the blood places against the blood vessels walls with each heartbeat. A person can experience elevated or high blood pressure, or hypertension, during pregnancy. This is when the blood puts more pressure than normal against the artery walls.

According to the AHA, people living with untreated high blood pressure are at a greater risk of developing a heart attack, stroke, or other health issues, such as kidney disease.

During pregnancy, high blood pressure is also known as gestational hypertension. Gestational hypertension occurs if the woman’s blood pressure is within the normal range for the first 20 weeks of pregnancy and then increases to 140/90 mm Hg or higher during the second half of the pregnancy.

Risk factors

Experts do not know the exact cause of gestational hypertension, but according to Cedars-Sinai, potential risk factors include:

having kidney disease
being younger than 20 or older than 40
being of African American descent
having diabetes
having a history of high blood pressure
having multiple pregnancies

In most cases, hypertension goes away after delivery.

Complications

ACOG indicate that gestational hypertension can cause complications or increase the risk of complications, such as:

preeclampsia and other hypertensive disorders of pregnancy typically occur after the 20th week of pregnancy and can lead to problems with the liver, kidney, or other organs
preterm delivery.
fetal growth restriction, which is a condition in which a lack of nutrients and oxygen can lead to lower birth weight
cesarean delivery
placental abruption, which occurs when the placenta separates from the wall of the uterus
stillbirth

Women who have high blood pressure before pregnancy should talk to their doctor or midwife. Their provider will likely closely monitor them and the fetus to make sure they are safe during the pregnancy.

Symptoms

In some cases, high blood pressure during pregnancy may not cause any symptoms.

If high blood pressure occurs as a result of preeclampsia, common symptoms include:

swelling, especially in the hands or face
a headache that does not go away with medication
rapid weight gain
only able to make small amounts of urine
visual disturbances
vomiting or nausea that begins or worsens after the 20th week of pregnancy
changes in vision
pain near the stomach or on the upper right side of the abdomen

Learn more about high blood pressure during pregnancy.

The AHA identify the first 24 weeks of pregnancy as a risk factor for developing low blood pressure. It can cause symptoms such as:

dizziness
fainting
blurred vision
inability to concentrate
cold or clammy skin
rapid breathing
fatigue
dehydration

For most adults, healthy blood pressure is usually less than 120/80 mm Hg. Low blood pressure, or hypotension, occurs when the blood pressure drops below 90/60 mm Hg.

Some people have a naturally low blood pressure, but a sudden drop can cause symptoms to develop.

Any pregnant woman who has any concerns over their health or the developing fetus should talk to or see their doctor or midwife.

People who have high blood pressure or are at greater risk of developing high blood pressure might want to monitor their blood pressure at home.

A healthcare provider can likely recommend the best blood pressure cuffs to use.

If home monitoring indicates that blood pressure is too high or too low, contact a healthcare provider.

Any pregnant woman who experiences signs or symptoms of preeclampsia must seek immediate medical assistance.

Learn more about preeclampsia here.

There are several ways for a pregnant woman to manage blood pressure safely.

According to March of Dimes, a person can take the following steps:

take approved blood pressure medication daily
monitor blood pressure at home
eat foods rich in nutrients and avoid salt, processed foods, and added sugars
go to all medical checkups
avoid drinking, smoking, and recreational drug use
stay active through walking or other exercises unless otherwise instructed

Women who have high blood pressure during pregnancy should follow all instructions from their healthcare provider. They should notify their doctor or midwife if they have any changes in their blood pressure or feelings.

It is not always possible to prevent high blood pressure, but a person can take steps to keep their blood pressure at normal levels before and during pregnancy.

The Centers for Disease Control and Prevention (CDC) recommend a person take the following measures to prevent high blood pressure:

talking to a healthcare provider before pregnancy about any existing health problems and medications
getting regular and early prenatal care
making sure all medications are safe to continue during pregnancy
eating healthful foods
exercising regularly

If a pregnant woman shows signs of low blood pressure, they should talk to their provider about the best course of action.

General treatment options for a person with low blood pressure include:

increasing the amount of sodium in the diet
increasing fluids
maintaining light to moderate exercise
standing from a sitting or lying position slowly
avoiding alcohol

A pregnant woman should maintain their normal blood pressure throughout pregnancy.

Women with previous high blood pressure, multiples, or other risk factors have a greater chance of developing high blood pressure in later pregnancy.

High blood pressure during pregnancy has associations with serious pregnancy complications, including preeclampsia and other hypertensive disorders.

If blood pressure gets too high or low, a person should talk to their healthcare provider to determine the best course of treatment.

High blood pressure during pregnancy

But its meaning is not always correctly controlled and interpreted. Let's figure out how to properly control blood pressure during pregnancy, which blood pressure is considered elevated, why it can rise and what should be done and what should not be done.

Blood pressure measurement

Blood pressure is monitored using a tonometer: electronic, semi-automatic or mechanical. You can buy any that you can handle and the cuff of which suits you in diameter. The only thing to consider is that the blood pressure cuff should be worn on the upper arm, carpal blood pressure monitors are too inaccurate and cannot be relied upon. nine0003

Measurement of blood pressure is best done in a sitting position, and after you have spent about fifteen minutes in this position, in a state of physical and emotional rest, you do not need to talk while measuring blood pressure.

The cuff is worn on the shoulder freed from clothing, its lower edge should be a few centimeters above the elbow. The arm on which blood pressure is measured should be in a relaxed position, the cuff should be located approximately at the level of the heart. Measurement is performed on one arm, measurement on two arms, which was previously required for all pregnant women, is now excluded from all clinical recommendations. nine0003

When measuring with a mechanical sphygmomanometer , air is inflated into the cuff to the digits, approximately twenty to thirty mm. rt. Art. higher than expected blood pressure. The air from the cuff is released slowly, the appearance of sound marks the numbers of systolic blood pressure, the disappearance of the sound - diastolic. This is not "cardiac" and "renal" pressure, but - systolic and diastolic.

Measurement of blood pressure is carried out at each visit to the obstetrician-gynecologist - office measurement of blood pressure, at home of the pregnant woman or her relative - outpatient measurement of blood pressure. If necessary, the doctor may recommend that the patient keep a blood pressure diary - measure blood pressure several times a day for some time, writing down the numbers. Ceteris paribus, more reliable information is obtained from outpatient (at home) measurements. nine0003

If there is doubt about the correctness of the patient's blood pressure measurement or if there is a suspicion of an increase in blood pressure at night, the doctor may prescribe the patient 24-hour blood pressure monitoring (ABPM), in which blood pressure is measured automatically at certain intervals within one day.

In general, during pregnancy, blood pressure in the first trimester is lower than normal for the patient, in the second or third it returns to her usual numbers, by the third trimester it may be slightly higher, but within the normal range. Blood pressure below 140/9 is considered normal during pregnancy.0 mm. rt. Art.

If the patient is prone to arterial hypotension (low blood pressure), elevated blood pressure is still considered to be blood pressure above 140/90 mm. rt. Art., lower figures do not require any additional examination or treatment, even if they are higher than usual for the patient. None of the clinical guidelines for the treatment of arterial hypertension during pregnancy indicate the need for treatment with higher blood pressure than usual, but not reaching a value of 140/90 mm. rt. Art.

AD 140/90 mm. rt. Art. and above must be recorded 2 or more times with an interval between measurements of at least 4 hours to be considered hypertension.

Causes of high blood pressure

There are three causes of high blood pressure during pregnancy: chronic arterial hypertension, gestational arterial hypertension and preeclampsia.

Chronic arterial hypertension is the general name for all cases of high blood pressure that existed before pregnancy. Chronic arterial hypertension is not divided into primary (due to unknown causes) and secondary (resulting from a disease), in contrast to arterial hypertension detected outside of pregnancy. Also, chronic arterial hypertension includes situations when a woman did not control blood pressure before pregnancy, and for the first time an increase in blood pressure was detected only in the first half (up to 20 weeks) of pregnancy. nine0003

Gestational hypertension occurs from the twentieth week until the end of the term, and is not accompanied by the excretion of protein in the urine.

Pre-eclampsia, in contrast to gestational hypertension, also develops after the 20th week of pregnancy, and is accompanied by the release of protein into the urine (proteinuria). Preeclampsia can also occur after delivery. Signs of an increase in the severity of preeclampsia are the appearance of a headache, dizziness, visual disturbances, pain in the solar plexus and / or in the right hypochondrium, pain under the right shoulder blade, respiratory failure, and some changes in blood tests. These signs require urgent hospitalization. nine0003

The extreme case of preeclampsia - eclampsia - is characterized by the occurrence of convulsions and threatens the life of both the mother and the child, therefore, it requires an emergency delivery, regardless of the gestational age, only in this way it becomes possible to save the life of the mother and child.

Since an increase in blood pressure may occur before proteinuria in preeclampsia, it is only possible to distinguish gestational arterial hypertension from preeclampsia in retrospect - if blood pressure increased, and protein did not appear in the daily urine, it can be said with certainty that this increase in blood pressure was due to specifically gestational hypertension. nine0053 Pre-eclampsia may be associated with chronic arterial hypertension that existed before pregnancy.

Treatment of Hypertensive Disorders

Hypertensive disorders are an important cause of maternal and perinatal death, increase the incidence of preterm birth, and are indeed a serious problem and should not be ignored.

The only one to date proven effective in preventing preeclampsia drug is acetylsalicylic acid. It is prescribed starting from the 13th week of pregnancy at a low dose and at this dosage does not lead to impaired fetal development, unlike high doses.

Treatment of any arterial hypertension during pregnancy is prescribed only by a doctor.

In chronic arterial hypertension uncomplicated by damage to other organs, treatment is started at BP 150/90 mm. rt. Art. and more, with gestational arterial hypertension and preeclampsia - with blood pressure 140/90 mm. rt. Art. and more.

During treatment, it is necessary to maintain blood pressure at the level of 130-150/80/95 mmHg. rt. Art., since a more radical decrease in blood pressure is fraught with impaired blood supply to the fetus and is not recommended.

There are several groups of antihypertensive drugs, the use of which during pregnancy can lead to impaired fetal development or death, so they should not be used during pregnancy. These are angiotensin-converting enzyme inhibitors and angiotensin II receptor antagonists. Do not use during pregnancy and diuretics (drugs with a diuretic effect). nine0053 Usually, treatment is started with methyldopa, but it is also possible to use certain drugs from the group of beta-blockers and some drugs from the group of calcium antagonists, which are best studied from the point of view of safety in pregnancy. It is possible to use combinations of these drugs.

Separately, a few words need to be said about magnesium sulfate (magnesium sulphate). This drug has practically no antihypertensive effect, and its use during pregnancy is limited only to preeclampsia, which threatens the development of eclampsia. It is needed to prevent the development of seizures (neuroprotective effect). It should not be used to influence elevated blood pressure. nine0003

Delivery for hypertension during pregnancy, is usually performed through the natural birth canal, except in cases of severe pre-eclampsia, eclampsia and their complications, requiring emergency delivery by caesarean section, regardless of the gestational age for health reasons.

Chronic arterial hypertension that persists during lactation and is not complicated by damage to other organs does not require medical treatment for blood pressure less than 150/95 mm. rt. Art. Arterial hypertension after childbirth does not require stopping breastfeeding; on the contrary, the protective effect of lactation in arterial hypertension has been proven.

If it is necessary to prescribe drug therapy , drugs are selected that are least able to be excreted into breast milk, the use of which has not been recorded serious side effects in the child.

Pregnancy and blood pressure

Pressure and pregnancy

Pregnancy is a period when the female body uses its full potential, all its reserves to provide everything you need to fully bear a child.

Blood pressure is one of the main parameters of blood flow intensity in the body. During the period of bearing a baby, a woman’s body is faced with the need to provide oxygen and nutrition not only for herself, but also for her unborn child. A change in the level of pressure during pregnancy becomes an indicator of disturbances in the functioning of the body that threaten the health of a woman and a child, and can also complicate the course of childbirth. nine0003

When blood pressure is measured

Blood pressure must be measured at every appointment with an obstetrician-gynecologist or therapist in the antenatal clinic of the expectant mother. But visits to the doctor's office should not be limited. It is necessary to independently measure this indicator in the morning and in the evening, so that the results can be compared, they must be recorded daily in a special notebook. Particular attention to their pressure should be shown by those women who previously had toxicosis of pregnancy, miscarriages, miscarriages. Women with hypertension, overweight, neurocircular and vegetovascular dystonia, diseases of the kidneys, heart, blood vessels should be on a special account, and measure pressure as often as recommended by the doctor. nine0003

The hourly measurement of blood pressure in at-risk pregnant women is called 24-hour monitoring. It is done three times during the entire period of pregnancy. The first time - at the very beginning of pregnancy, to identify a woman's tendency to hypertension, the second time - at 24-28 weeks of pregnancy, to identify a predisposition to preeclampsia or late toxicosis of pregnant women, the third time - before childbirth, to determine the degree of risk to the woman and the fetus , as well as to resolve the issue of the method of obstetrics. nine0003

If there are problems with pressure in a pregnant woman, then it is necessary to visit a cardiologist and a therapist who can advise what needs to be done to solve the problem of pressure during pregnancy.

Types of blood pressure monitors

There are two types of blood pressure monitors (blood pressure monitor) - mechanical and electronic.

Mechanical blood pressure monitor used by physicians. It gives the most accurate results. You can learn how to use a mechanical tonometer at home. However, taking blood pressure on your own is very difficult, so if you want to use this type of blood pressure monitor, you will need an assistant. nine0116
Electronic blood pressure monitor is easier to use. It is enough to put the cuff on your arm and press the button. The device itself will do the rest, and you will only have to read the results on the electronic scoreboard. An electronic tonometer shows the value of blood pressure and pulse, memorizing the indicators. There are blood pressure monitors, the cuff of which can be worn on the shoulder, on the wrist and even on the finger. For the home, the most suitable device is the cuff of which is worn on the shoulder. Wrist or finger gauges can be used to measure blood pressure at work or while traveling. nine0116

Correct measurement of blood pressure

Do not immediately panic because of high or low pressure during pregnancy, you need to make sure that the measurement is correct.

There are several important rules for the correct determination of blood pressure:

Before measuring, sit down and rest for a couple of minutes, think about something pleasant. Stress is one of the factors in the short-term increase in pressure.
Place the cuff on your bare arm or thin fabric. It must be sized. nine0116
Measure blood pressure on both arms.
Never round the received numbers and write them down.
It is not recommended to determine the level of blood pressure after a meal or after exercise.

Blood pressure during pregnancy: norm and deviations

Blood pressure is the force of blood flow pressure on the wall of blood vessels. It is measured in millimeters of mercury (mm Hg) and is written in two numbers separated by a slash. nine0003

The first digit shows the pressure at the moment of maximum contraction of the heart (systolic blood pressure), and the second - at the time of its complete relaxation (diastolic blood pressure). If blood pressure is normal, we can safely say that the mother’s cardiovascular system is doing its job, which means that all organs receive a sufficient amount of oxygen and nutrients brought with the bloodstream.

Outside of pregnancy, normal blood pressure ranges from 100/60 to 130/80 mmHg. Art. During pregnancy, the pressure may differ slightly from the original: if it is 10% lower or higher than usual, then such changes are still within the normal range. If the pressure is lower or higher than usual by 15–20% or more, then we are dealing with arterial hypotension (low blood pressure) or arterial hypertension (high blood pressure). It is desirable for a woman to know her usual level of pressure, which was before pregnancy, so that the doctor can draw the right conclusions. nine0003

1.1 What is the danger of changes in blood pressure

During pregnancy, nutrients and oxygen are constantly supplied to the fetus through the vasculature of the placenta, and the products of its vital activity are returned to the mother.

This exchange is only possible at an optimum pressure level. Changes in blood pressure in one direction or the other can have adverse effects.

Under reduced pressure, transport deteriorates and the amount of substances needed by the child decreases, which can lead to fetal growth retardation syndrome. And a significant increase in blood pressure can cause damage to microvessels, foci of hemorrhages are formed, which can lead to placental abruption. That is why during pregnancy it is so important to control blood pressure and keep it at an optimal level. nine0003

Normal blood pressure during pregnancy

The norms of blood pressure accepted in general medicine range from 100/60 to 120/80 mm Hg. But during pregnancy, these indicators may change somewhat. Usually in the early stages (the entire 1st trimester and up to 20 weeks), these numbers slightly decrease, which is associated with a change in the hormonal background of the whole organism and a restructuring of metabolic processes.

Later, as the fetus grows and develops more intense blood flow to feed it, the pressure may increase relative to "non-pregnant" values. Because of this, the average norms for expectant mothers lie in a wider range - from 105/60 to 139/89 mmHg

Significant deviations from this range upwards are called gestational hypertension, and downwards are called hypotension.

Low blood pressure during pregnancy or hypotension

In the first months of pregnancy, the hormonal background of the expectant mother undergoes significant changes, works with a great load, creating a favorable background for the development of the child, and these changes are often accompanied by a decrease in blood pressure, hypotension.

1.1.1 Possible causes of hypotension

Sometimes it is impossible to determine the cause that provoked the appearance of such a disorder, but the following may play a role in its development:

Hormonal changes;
NDC for hypotonic type;
Infectious diseases;
Liver pathology;
Taking certain medications;
Features of woman's emotionality.

Pregnancy hypotension is often not perceived as a serious threat to the health and progress of pregnancy. However, it can be a serious pathogenic factor that provokes various disorders of the course of pregnancy:

Termination of pregnancy
Fetal growth retardation
Oxygen starvation baby
Weak labor activity
Possible bleeding after separation of the placenta
Relaxation of the uterus after childbirth and rebleeding

1.1.2 Main symptoms of hypotension:

Nausea, vomiting
Headache
Ringing in the ears
Shortness of breath
Dizziness
Increased fatigue
Drowsiness
Pale skin
Increased perspiration
Loss of consciousness

1.1.3 How to increase blood pressure or what to do with low blood pressure

In general, women with low blood pressure are not hospitalized unless there is a risk to the baby. Expectant mothers are observed by an obstetrician-gynecologist, a therapist and, if necessary, a cardiologist. Most often, in the third trimester, the pressure returns to normal. nine0003

Pregnant women should follow these guidelines:

Get at least 8 hours of sleep (optimally 9-10 hours) and rest during the day if possible.
Spend more time outdoors (at least 2 hours a day).
Food should be taken in small portions, but throughout the day.
Moderate physical activity recommended - do prenatal gymnastics; if possible, swim. nine0116
Water procedures are useful - shower, dousing, contrast foot baths, as well as massage; physiotherapy (electrosleep, salt-coniferous and mineral baths) and acupuncture are successfully used for treatment.
If necessary, doctors can prescribe drug therapy: usually, pregnant women are prescribed herbal preparations that increase the tone of the autonomic nervous system, such as eleutherococcus extracts, radiols, tinctures of magnolia vine, aralia, zamaniha in combination with sedatives (valerian, motherwort), as well as drugs based on caffeine. nine0116

If a pregnant woman has lost consciousness due to a sudden drop in blood pressure, the first thing to do is to lay her horizontally on her side and call an ambulance. Then open the door or window, unfasten the collar, give a sniff of ammonia. You can massage the area between the nose and lip or act on the fingertips on the hands.

High blood pressure during pregnancy or hypertension

Arterial hypertension is a disease characterized by a persistent increase in blood pressure. The changes that occur in the body during pregnancy predispose to the development of hypertension and therefore pregnant women are at a higher risk of developing hypertension than the general population. Arterial hypertension is a risk factor for various complications of pregnancy and ranks second in the list of causes of maternal death. At the same time, the diagnosis and treatment of arterial hypertension in pregnant women requires a special approach. nine0003

If before pregnancy you noted that your blood pressure was higher than normal, took pills, visited the appropriate doctors, be prepared that this problem will come up now. And, most likely, it will manifest itself with greater force.

Remember: now the situation is completely different, you do not need to take the same pills as before pregnancy.

Forms of arterial hypertension during pregnancy

Arterial hypertension of pregnancy is an increase in blood pressure during pregnancy. It is regarded as a persistent increase in systolic blood pressure above 140 mm Hg. and diastolic blood pressure above 90 mmHg in women with normal blood pressure before pregnancy. Women with such an increase in pressure require close medical supervision.

There are several types of arterial hypertension during pregnancy:

Chronic hypertension is characterized by the presence of high blood pressure before pregnancy and its persistence after pregnancy.
Arterial hypertension of pregnancy is a persistent increase in blood pressure that develops after the 20th week of pregnancy, which disappears at the end of pregnancy. nine0116
Pre-eclampsia/eclampsia is a severe impairment of the cardiovascular system and kidneys during pregnancy, which includes: hypertension and impaired renal function.

In pregnant women, arterial hypertension occurs with a frequency of 4-8%, which is a very high figure, especially if you take into account the young age of most expectant mothers. During pregnancy, the woman's body adapts to new conditions of functioning, which include ensuring the life and development of the fetus. On the part of the cardiovascular system in the body of a pregnant woman, the following changes occur:

An increase in the volume of circulating blood and the appearance of a placental circulatory system is necessary for the nutrition and development of the child. In pregnant women, the volume of circulating blood increases by 25-30%, which, in addition to ensuring the nutrition of the child, allows women to lose part of the blood during childbirth, without significant damage to health.
Increased heart rate.
An increase in intra-abdominal pressure, an increase in the diaphragm, and a change in the position of the heart in the chest due to a significant increase in the size of the uterus. nine0116
Gradual weight gain in a pregnant woman.

Possible other causes of high blood pressure

Exercise
Drinking strong tea or coffee
Chronic stress, fatigue, lack of sleep, emotional stress
Smoking, alcohol abuse
Unbalanced diet, lack of vitamins and minerals
Obesity, overweight
Multiple pregnancy
Lack of physical activity
Diseases of the thyroid gland
Diseases of the adrenal glands
Diabetes mellitus
Head, brain and spinal cord injuries
Encephalitis
Myelitis
Diseases of the heart and blood vessels
Renal impairment
Hereditary predisposition

Main symptoms of hypertension:

Headache
Nausea, vomiting
Dizziness, weakness, impotence
Redness of the skin of the hands and face
Noise or ringing in the ears
Visual impairment
Edema
Urinary protein excretion
Convulsions

High blood pressure can cause complications such as retinal detachment or retinal haemorrhage, which can lead to partial or complete loss of vision. nine0003

If blood pressure began to rise in the second or third trimester of pregnancy, then we are probably dealing with a serious complication of pregnancy - preeclampsia.

Preeclampsia is a special condition that occurs only during pregnancy and ends with its completion. Manifestations of preeclampsia are varied, but the classic symptoms are:

arterial hypertension
edema
proteinuria (protein in urine)

With preeclampsia, there is a violation of microcirculation in all vital organs: the blood supply to the brain worsens, kidney failure develops, the blood becomes viscous, and the resulting microthrombi disrupt the work of all organs and systems. Of particular danger is such damage to the vessels of the placenta and the brain. The most severe manifestation of preeclampsia - eclampsia - convulsive seizures, ending in a cerebral coma.

But preeclampsia often begins with a pathological increase in body weight. Expectant mothers often wonder why this doctor pays such attention to weight. Well, think about it, added a couple of extra pounds. nine0003

But after all, such an increase is due to fluid retention in the body, or the so-called latent edema.

And if treatment is not started in time, all manifestations of preeclampsia will not be long in coming. If there was an increase in blood pressure before the onset of pregnancy, then its successful course is possible only with good preparation and the correct selection of drugs that reduce pressure. With uncomplicated hypertension and a slight increase in pressure, only non-drug measures are sufficient. nine0003

Treatment and prevention of arterial hypertension during pregnancy

Treatment of arterial hypertension during pregnancy is a complex and responsible task. Therefore, the basis of any type of treatment should be close cooperation between the patient and the doctor.

In the treatment of arterial hypertension in pregnancy, as well as in the treatment of arterial hypertension, the following methods are used: non-drug treatment and drug treatment. nine0003

Non-drug treatment, i.e. treatment without drugs, is the most appropriate treatment for hypertension during pregnancy, since many of the drugs used in the treatment of this disease can be dangerous to the fetus.

What to do with pressure, how to reduce pressure during pregnancy

Non-drug treatment and prevention of arterial hypertension includes:

Diet. The main requirements for the diet of women suffering from hypertension are a reduction in the consumption of table salt, coffee, tea, and the rejection of bad habits. The allowable amount of salt per day for patients with hypertension is 5 grams, while the calculation must include not only the salt with which we season food, but also the salt contained in various foods. nine0116
Physical activity. Moderate physical activity has a positive effect on the general condition of the body, promotes fat burning, normalizes metabolism, improves blood supply to internal organs and the fetus, increases muscle tone and helps to establish the correct position of the fetus in the uterus. For the treatment and prevention of arterial hypertension during pregnancy, daily physical activity in the form of gymnastics (preferably with an instructor), hiking in the fresh air, and swimming are recommended. nine0116
Maintain normal body weight. The common expression that during pregnancy a woman "should eat for two" is not true. In fact, an "energy supplement" during pregnancy should not exceed 350 kcal. At the same time, maintaining normal body weight during pregnancy is extremely important for maintaining the health of the pregnant woman herself and her child (obesity contributes to the development of hypertension and diabetes). The normal weight gain of a pregnant woman by the end of pregnancy should not exceed 12 kg. nine0116
