Preeclampsia what to do


Preeclampsia - Diagnosis and treatment

Diagnosis

A diagnosis of preeclampsia happens if you have high blood pressure after 20 weeks of pregnancy and at least one of the following findings:

  • Protein in your urine (proteinuria), indicating an impaired kidney
  • Other signs of kidney problems
  • A low blood platelet count
  • Elevated liver enzymes showing an impaired liver
  • Fluid in the lungs (pulmonary edema)
  • New headaches that don't go away after taking pain medication
  • New vision disturbances

High blood pressure

A blood pressure reading has two numbers. The first number is the systolic pressure, a measure of blood pressure when the heart is contracting. The second number is the diastolic pressure, a measure of blood pressure when the heart is relaxed.

In pregnancy, high blood pressure is diagnosed if the systolic pressure is 140 millimeters of mercury (mm Hg) or higher or if the diastolic pressure is 90 mm Hg or higher.

A number of factors can affect your blood pressure. If you have a high blood pressure reading during an appointment, your health care provider will likely take a second reading four hours later to confirm a diagnosis of high blood pressure.

Additional tests

If you have high blood pressure, your health care provider will order additional tests to check for other signs of preeclampsia:

  • Blood tests. A blood sample analyzed in a lab can show how well the liver and kidneys are working. Blood tests can also measure the amount of blood platelets, the cells that help blood clot.
  • Urine analysis. Your health care provider will ask you for a 24-hour urine sample or a single urine sample to determine how well the kidneys are working.
  • Fetal ultrasound. Your primary care provider will likely recommend close monitoring of your baby's growth, typically through ultrasound. The images of your baby created during the ultrasound exam allow for estimates of the baby's weight and the amount of fluid in the uterus (amniotic fluid).
  • Nonstress test or biophysical profile. A nonstress test is a simple procedure that checks how your baby's heart rate reacts when your baby moves. A biophysical profile uses an ultrasound to measure your baby's breathing, muscle tone, movement and the volume of amniotic fluid in your uterus.

Treatment

The primary treatment for preeclampsia is either to deliver the baby or manage the condition until the best time to deliver the baby. This decision with your health care provider will depend on the severity of preeclampsia, the gestational age of your baby, and the overall health of you and your baby.

If preeclampsia isn't severe, you may have frequent provider visits to monitor your blood pressure, any changes in signs or symptoms, and the health of your baby. You'll likely be asked to check your blood pressure daily at home.

Treatment of severe preeclampsia

Severe preeclampsia requires that you be in the hospital to monitor your blood pressure and possible complications. Your health care provider will frequently monitor the growth and well-being of your baby.

Medications to treat severe preeclampsia usually include:

  • Antihypertensive drugs to lower blood pressure
  • Anticonvulsant medication, such as magnesium sulfate, to prevent seizures
  • Corticosteroids to promote development of your baby's lungs before delivery

Delivery

If you have preeclampsia that isn't severe, your health care provider may recommend preterm delivery after 37 weeks. If you have severe preeclampsia, your health care provider will likely recommend delivery before 37 weeks, depending on the severity of complications and the health and readiness of the baby.

The method of delivery — vaginal or cesarean — depends on the severity of disease, gestational age of the baby and other considerations you would discuss with your health care provider.

After delivery

You need to be closely monitored for high blood pressure and other signs of preeclampsia after delivery. Before you go home, you'll be instructed when to seek medical care if you have signs of postpartum preeclampsia, such as severe headaches, vision changes, severe belly pain, nausea and vomiting.

Coping and support

Discovering that you have a potentially serious pregnancy complication can be frightening.

If you're diagnosed with preeclampsia late in your pregnancy, you may be surprised to learn that immediate delivery may be recommended. If you're diagnosed earlier in your pregnancy, you may be concerned about monitoring signs and symptoms at home and keeping more frequent appointments with your primary care provider.

It may help to learn more about your condition. In addition to talking to your provider, do some research. Make sure you understand when to call your provider and how to monitor signs and symptoms.

Preparing for your appointment

Preeclampsia is often diagnosed during a regularly scheduled prenatal appointment. If your primary care provider recommends certain tests for a preeclampsia diagnosis, you may also be discussing some of the following questions:

  • Did you have preeclampsia or other complications in a previous pregnancy?
  • If you're having symptoms of preeclampsia, when did they begin?
  • Has anything improved the symptoms or made them worse?
  • Have you made any recent changes to your medications, vitamins or dietary supplements?

After a diagnosis of preeclampsia and at follow-up appointments, you might ask the following questions:

  • How can I make sure I'm doing blood pressure readings correctly at home?
  • How often should I check my blood pressure at home?
  • What blood pressure reading should I consider high?
  • When should I call the clinic?
  • When should I get emergency care?
  • How will we monitor my baby's health?
  • When should I schedule my next appointment?
  • How will we decide on the right time for delivery?
  • What are the benefits and risks of delaying delivery?
  • What care might my baby need after a preterm delivery?

Preeclampsia - Symptoms and causes

Overview

Preeclampsia is a complication of pregnancy. With preeclampsia, you might have high blood pressure, high levels of protein in urine that indicate kidney damage (proteinuria), or other signs of organ damage. Preeclampsia usually begins after 20 weeks of pregnancy in women whose blood pressure had previously been in the standard range.

Left untreated, preeclampsia can lead to serious — even fatal — complications for both the mother and baby.

Early delivery of the baby is often recommended. The timing of delivery depends on how severe the preeclampsia is and how many weeks pregnant you are. Before delivery, preeclampsia treatment includes careful monitoring and medications to lower blood pressure and manage complications.

Preeclampsia may develop after delivery of a baby, a condition known as postpartum preeclampsia.

Symptoms

The defining feature of preeclampsia is high blood pressure, proteinuria, or other signs of damage to the kidneys or other organs. You may have no noticeable symptoms. The first signs of preeclampsia are often detected during routine prenatal visits with a health care provider.

Along with high blood pressure, preeclampsia signs and symptoms may include:

  • Excess protein in urine (proteinuria) or other signs of kidney problems
  • Decreased levels of platelets in blood (thrombocytopenia)
  • Increased liver enzymes that indicate liver problems
  • Severe headaches
  • Changes in vision, including temporary loss of vision, blurred vision or light sensitivity
  • Shortness of breath, caused by fluid in the lungs
  • Pain in the upper belly, usually under the ribs on the right side
  • Nausea or vomiting

Weight gain and swelling (edema) are typical during healthy pregnancies. However, sudden weight gain or a sudden appearance of edema — particularly in your face and hands — may be a sign of preeclampsia.

When to see a doctor

Make sure you attend your prenatal visits so that your health care provider can monitor your blood pressure. Contact your provider immediately or go to an emergency room if you have severe headaches, blurred vision or other visual disturbances, severe belly pain, or severe shortness of breath.

Because headaches, nausea, and aches and pains are common pregnancy complaints, it's difficult to know when new symptoms are simply part of being pregnant and when they may indicate a serious problem — especially if it's your first pregnancy. If you're concerned about your symptoms, contact your doctor.

Causes

The exact cause of preeclampsia likely involves several factors. Experts believe it begins in the placenta — the organ that nourishes the fetus throughout pregnancy. Early in a pregnancy, new blood vessels develop and evolve to supply oxygen and nutrients to the placenta.

In women with preeclampsia, these blood vessels don't seem to develop or work properly. Problems with how well blood circulates in the placenta may lead to the irregular regulation of blood pressure in the mother.

Other high blood pressure disorders during pregnancy

Preeclampsia is one high blood pressure (hypertension) disorder that can occur during pregnancy. Other disorders can happen, too:

  • Gestational hypertension is high blood pressure that begins after 20 weeks without problems in the kidneys or other organs. Some women with gestational hypertension may develop preeclampsia.
  • Chronic hypertension is high blood pressure that was present before pregnancy or that occurs before 20 weeks of pregnancy. High blood pressure that continues more than three months after a pregnancy also is called chronic hypertension.
  • Chronic hypertension with superimposed preeclampsia occurs in women diagnosed with chronic high blood pressure before pregnancy, who then develop worsening high blood pressure and protein in the urine or other health complications during pregnancy.

Risk factors

Conditions that are linked to a higher risk of preeclampsia include:

  • Preeclampsia in a previous pregnancy
  • Being pregnant with more than one baby
  • Chronic high blood pressure (hypertension)
  • Type 1 or type 2 diabetes before pregnancy
  • Kidney disease
  • Autoimmune disorders
  • Use of in vitro fertilization

Conditions that are associated with a moderate risk of developing preeclampsia include:

  • First pregnancy with current partner
  • Obesity
  • Family history of preeclampsia
  • Maternal age of 35 or older
  • Complications in a previous pregnancy
  • More than 10 years since previous pregnancy

Other risk factors

Several studies have shown a greater risk of preeclampsia among Black women compared with other women. There's also some evidence of an increased risk among indigenous women in North America.

A growing body of evidence suggests that these differences in risk may not necessarily be based on biology. A greater risk may be related to inequities in access to prenatal care and health care in general, as well as social inequities and chronic stressors that affect health and well-being.

Lower income also is associated with a greater risk of preeclampsia likely because of access to health care and social factors affecting health.

For the purposes of making decisions about prevention strategies, a Black woman or a woman with a low income has a moderately increased risk of developing preeclampsia.

Complications

Complications of preeclampsia may include:

  • Fetal growth restriction. Preeclampsia affects the arteries carrying blood to the placenta. If the placenta doesn't get enough blood, the baby may receive inadequate blood and oxygen and fewer nutrients. This can lead to slow growth known as fetal growth restriction.
  • Preterm birth. Preeclampsia may lead to an unplanned preterm birth — delivery before 37 weeks. Also, planned preterm birth is a primary treatment for preeclampsia. A baby born prematurely has increased risk of breathing and feeding difficulties, vision or hearing problems, developmental delays, and cerebral palsy. Treatments before preterm delivery may decrease some risks.
  • Placental abruption. Preeclampsia increases your risk of placental abruption. With this condition, the placenta separates from the inner wall of the uterus before delivery. Severe abruption can cause heavy bleeding, which can be life-threatening for both the mother and baby.
  • HELLP syndrome. HELLP stands for hemolysis (the destruction of red blood cells), elevated liver enzymes and low platelet count. This severe form of preeclampsia affects several organ systems. HELLP syndrome is life-threatening to the mother and baby, and it may cause lifelong health problems for the mother.

    Signs and symptoms include nausea and vomiting, headache, upper right belly pain, and a general feeling of illness or being unwell. Sometimes, it develops suddenly, even before high blood pressure is detected. It also may develop without any symptoms.

  • Eclampsia. Eclampsia is the onset of seizures or coma with signs or symptoms of preeclampsia. It is very difficult to predict whether a patient with preeclampsia will develop eclampsia. Eclampsia can happen without any previously observed signs or symptoms of preeclampsia.

    Signs and symptoms that may appear before seizures include severe headaches, vision problems, mental confusion or altered behaviors. But, there are often no symptoms or warning signs. Eclampsia may occur before, during or after delivery.

  • Other organ damage. Preeclampsia may result in damage to the kidneys, liver, lung, heart, or eyes, and may cause a stroke or other brain injury. The amount of injury to other organs depends on how severe the preeclampsia is.
  • Cardiovascular disease. Having preeclampsia may increase your risk of future heart and blood vessel (cardiovascular) disease. The risk is even greater if you've had preeclampsia more than once or you've had a preterm delivery.

Prevention

Medication

The best clinical evidence for prevention of preeclampsia is the use of low-dose aspirin. Your primary care provider may recommend taking an 81-milligram aspirin tablet daily after 12 weeks of pregnancy if you have one high-risk factor for preeclampsia or more than one moderate-risk factor.

It's important that you talk with your provider before taking any medications, vitamins or supplements to make sure it's safe for you.

Lifestyle and healthy choices

Before you become pregnant, especially if you've had preeclampsia before, it's a good idea to be as healthy as you can be. Talk to your provider about managing any conditions that increase the risk of preeclampsia.

Preeclampsia and pregnancy | Ida-Tallinna Keskhaigla

The purpose of this leaflet is to provide the patient with information about the nature, occurrence, risk factors, symptoms and treatment of preeclampsia.

What is preeclampsia?

Pre-eclampsia is a disease that occurs during pregnancy and is characterized by high blood pressure and protein in the urine. Preeclampsia is one of the most common complications of pregnancy. Epilepsy-like seizures occur in severe preeclampsia and are life-threatening.

What symptoms may indicate the development of preeclampsia?

High blood pressure - blood pressure values ​​are 140/90 mmHg. Art. or higher. If systolic (upper) or diastolic (lower) blood pressure rises by 30 mm Hg. Art. or more, then such an increase cannot be ignored.

Protein in urine - 300 mg in urine collected over 24 hours, or +1 value on a rapid test.

Swelling of the arms, legs or face , especially under the eyes or if the swelling leaves a depression in the skin when pressed. Edema can occur in all pregnant women and is generally harmless, but rapidly developing edema should be taken into account.

Headache that does not improve after taking pain medication.

Visual disturbances - double vision or blurred vision, dots or flashes before the eyes, auras.

Nausea or pain in the upper abdomen - These symptoms are often mistaken for indigestion or gallbladder pain. Nausea in the second half of pregnancy is not normal.

Sudden weight gain - 2 kg or more per week.

As a rule, there is a mild course of the disease that occurs at the end of pregnancy and has a good prognosis. Sometimes, preeclampsia can worsen quickly and be dangerous to both mother and fetus. In such cases, rapid diagnosis and careful monitoring of the mother and child are of paramount importance.

Unfortunately, most women show symptoms in the final stages of the disease. If you experience any of the above symptoms, you should contact your midwife, gynecologist, or the Women's Clinic emergency department.

Is preeclampsia called toxemia of pregnancy?

Previously, pre-eclampsia was really called toxicosis, or toxemia, since it was believed that the cause of the disease was toxins, that is, poisons in the blood of a pregnant woman.

What is the difference between preeclampsia and gestational hypertension?

Pregnancy hypertension is an increase in blood pressure above normal after the 20th week of pregnancy. With hypertension of pregnant women, protein in the urine is not observed.

What is HELLP syndrome?

HELLP syndrome is one of the most severe forms of preeclampsia. HELLP syndrome is rare and sometimes develops before symptoms of preeclampsia appear. Sometimes the syndrome is difficult to diagnose, as the symptoms resemble gallbladder colic or a cold.

When does preeclampsia occur?

Preeclampsia usually occurs after the 20th week of pregnancy. As a rule, preeclampsia goes away after delivery, but complications can occur up to six weeks after delivery, during which careful monitoring of the condition is necessary. If by the sixth week after birth, blood pressure does not return to normal, then you need to contact a cardiologist, who will begin treatment against hypertension.

What is the cause of preeclampsia?

The causes of the disease are still not clear, there are only unproven hypotheses.

How does the disease affect pregnant women and pregnancy?

Most preeclamptic pregnancies have a favorable outcome and a healthy baby is born. However, the disease is very serious and is one of the most common causes of death of the child and mother. Preeclampsia affects a woman's kidneys, liver, and other vital organs, and if left untreated, it can cause seizures (eclampsia), cerebral hemorrhage, multiple organ failure, and death.

How does the disease affect the fetus?

In preeclampsia, the fetus does not receive enough oxygen and nutrients to grow, and intrauterine growth retardation may occur. In addition, the placenta may separate from the uterine wall before the baby is born. Since the only treatment for preeclampsia is childbirth, sometimes a pregnancy has to be terminated prematurely. Until the 34th week of pregnancy, the lungs of the fetus have not yet matured, and steroid hormones are administered intravenously to the pregnant woman to prepare her lungs. In addition to the immaturity of the lungs, the health of a premature baby is threatened by many other diseases.

Who is at risk of developing preeclampsia?

Preeclampsia occurs in approximately 8% of pregnant women, many of whom have no known risk factors.

What are the risk factors for preeclampsia?

Patient-related risk factors

  • First pregnancy

  • Pre-eclampsia during a previous pregnancy

  • Age over 40 or under 18

  • High blood pressure before pregnancy

  • Diabetes before or during pregnancy

  • Multiple pregnancy

  • Overweight (BMI> 30)

  • Systemic lupus erythematosus or other autoimmune disease

  • Polycystic ovary syndrome

  • Long interval between two pregnancies

Risk factors associated with the patient's family

What is the prevention and treatment of preeclampsia

During the first trimester screening, or Oscar test, in addition to the most common chromosomal diseases, the risk of preeclampsia is also calculated. In case of high risk, pregnant women are advised to take aspirin (acetylsalicylic acid) at a dose of 150 mg in the evenings until the 36th week of pregnancy. This helps reduce the chance of preeclampsia by the 34th week of pregnancy by up to 80%.

Childbirth is the only treatment for preeclampsia. Sometimes a child can be born naturally, but sometimes, if the disease is very acute, an emergency caesarean section is necessary. The best time to have a baby is after the 37th week of pregnancy. Bed rest, medications, and, if necessary, hospitalization can sometimes help bring the condition under control and prolong the pregnancy. Often, a doctor will refer a woman with preeclampsia to the hospital for observation, as the condition of the fetus and pregnant woman may suddenly worsen.

Does bed rest help?

Sometimes bed rest is enough to bring mild preeclampsia under control. In this case, the patient often visits a doctor who measures blood pressure, does blood and urine tests, and monitors the course of the disease. The condition of the fetus is also often examined using a cardiotocogram (CTG) and ultrasound.

Are drugs used to treat preeclampsia?

High blood pressure sometimes requires medication. The medications used have few side effects, the drugs prescribed do not have much effect on the fetus, but are very important in the treatment of maternal high blood pressure.

Seizures are a rare but very serious complication of preeclampsia. Magnesium sulfate is sometimes given intravenously to prevent seizures in a pregnant woman with preeclampsia both during and after childbirth. It is safe for the fetus, but the mother may experience side effects such as hot flashes, sweating, thirst, visual disturbances, mild confusion, muscle weakness, and shortness of breath. All these side effects disappear when the drug is discontinued.

Can preeclampsia recur?

Preeclampsia does not necessarily recur in the next pregnancy, but the main risk factor for preeclampsia is the presence of preeclampsia in a previous pregnancy(s). Risk factors for relapse include the severity of the previous case and the woman's overall health during pregnancy. A woman who has previously had preeclampsia should consult a gynecologist during a new pregnancy or when planning a pregnancy.

pre-eclampsia

Every mother-to-be wants her pregnancy to be a time of joyful anticipation. But the fear of preeclampsia can darken the joy.

What is preeclampsia?

Pre-eclampsia is a potentially life-threatening disease that occurs during pregnancy and affects multiple organ systems and is characterized by high maternal blood pressure and protein in the urine, or in the absence of the latter, dysfunction of other organ systems. This can affect both you and your unborn child. If the risk of preeclampsia is known in advance, it can be prevented.

How common is preeclampsia?

Most women have a normal pregnancy. At the same time, pre-eclampsia is a relatively common disease during pregnancy, which occurs in two out of a hundred women in Estonia.

When does preeclampsia occur?

Pre-eclampsia occurs after the 20th week of pregnancy or up to six weeks after delivery. Most often, preeclampsia occurs between the 32nd and 36th weeks of pregnancy. The earlier in pregnancy the disease occurs, the more severe its course, and the more dangerous it is for the mother and child.

What causes preeclampsia?

The exact causes of preeclampsia are unknown, but it is believed that they lie in the violation of the attachment of the developing placenta to the uterus, as a result of which there is no reliable connection between the circulatory systems of the mother and child. At the same time, a rapidly developing fetus requires oxygen and nutrients from the mother's circulatory system for its growth. If oxygen deficiency occurs in the developing placenta, toxic substances are released into the mother's circulatory system, which damage the lining of the mother's blood vessels. This is how a systemic lesion of the internal organs of the mother is formed. In order to save the lives of mother and child, the child must be born. If this happens at a very early stage of pregnancy, the baby is not yet ready for extrauterine life.

How will this affect me?

Mostly there is a mild form of the disease that occurs at the end of pregnancy and the prognosis for which is good. But sometimes pre-eclampsia can get worse very quickly and begin to threaten the lives of the mother and child. Preeclampsia also has a long-term effect on a woman's health, as it doubles the incidence of cardiovascular disease in the future. Most women with preeclampsia are hospitalized, and often their children have to be born prematurely. If the health of the mother or child is at risk, labor is induced or a caesarean section is performed.

How will this affect my child?

Most children remain healthy even when their mothers have severe preeclampsia. But sometimes preeclampsia can threaten the life and health of both the fetus and the newborn. Maternal preeclampsia doubles the risk of a surviving child suffering from cerebral palsy, that is, brain damage that results in delayed physical and sometimes mental development. In addition, surviving children are more likely to develop cardiovascular disease, obesity and diabetes in the future. In preeclampsia, there is not enough oxygen and nutrients for the growth of the fetus, and intrauterine growth retardation occurs. Since the only treatment for preeclampsia is childbirth, sometimes the pregnancy has to be terminated. Until the 34th week of pregnancy, the lungs of the fetus have not yet fully developed, and steroid injections are given to the pregnant woman to stimulate them.

How to recognize preeclampsia?

Unfortunately, in most women, the symptoms of the disease appear only at an advanced stage.

  • Chronic headache not responding to painkillers
  • Severe nausea and vomiting
  • Visual disturbances, tinnitus
  • Pain in the right hypochondrium
  • Feeling short of breath, shortness of breath
  • Infrequent urge to urinate (less than 500 ml per day)
  • Edema of hands, face and eyelids
  • Rapid weight gain (more than 1 kg per week)

If you experience any of the above symptoms, contact your obstetrician, gynecologist or hospital doctor on call.

Am I at risk?

Although all pregnant women can develop preeclampsia, some women are more at risk than others.

You are at greater risk if

  • this is your first pregnancy;
  • you had preeclampsia during a previous pregnancy;
  • your sister or mother had preeclampsia;
  • Your body mass index is 35 kg/m 2 or more;
  • You are at least 40 years old;
  • the time between births was more than 10 years;
  • You are expecting twins;
  • You have become pregnant in vitro;
  • you have any medical problem, such as hypertension, kidney problems, lupus, diabetes;
  • You developed diabetes during this pregnancy.

At what stage of pregnancy is screening performed?

Screening for preeclampsia can be done in all three trimesters.

  • First trimester, 11–13 weeks +6 weeks (as part of the OSCAR test)
  • Second trimester, 19-21 weeks +6 weeks (as part of fetal anatomy screening)
  • Third trimester, 34-36 weeks (as part of a growth and fetal study)

A three-stage screening test for preeclampsia can prevent it from occurring or move it to a later stage of pregnancy.

How reliable is screening for preeclampsia?

In the first trimester, the OSCAR test can identify women at risk of developing early preeclampsia with 76% accuracy before the 37th week of pregnancy. Among pregnant twins, all women who can develop early preeclampsia can be identified before the 37th week of pregnancy.

In the second trimester, fetal anatomy screening can identify women at risk of developing early preeclampsia with an accuracy of 85% before the 37th week of pregnancy.

In the 3rd trimester, growth and fetal ultrasound can identify women at risk for developing late preeclampsia after 37 weeks of pregnancy with 85% accuracy.

Why should I assess my risk for preeclampsia?

The best way to assess the risk of early preeclampsia is in the first trimester with the OSCAR test, when at-risk women will benefit from the anti-preeclampsia effect of aspirin. Studies have shown that small doses of aspirin before the 16th week of pregnancy in 62% of cases reduce the risk of early preeclampsia, which may require delivery before the 37th week. Therefore, women with an increased risk of preeclampsia are advised to take 150 milligrams of aspirin once a day, in the evenings, until the 36th week of pregnancy. The goal of prophylactic treatment for women at high risk of preeclampsia is either to avoid the development of preeclampsia or to postpone its occurrence until later in pregnancy, when the child is ready for birth.

During the second trimester, fetal anatomy screening may reassess the OSCAR risk for preeclampsia or recommend screening for preeclampsia in women who were not assessed for preeclampsia by OSCAR.

In the third trimester, ultrasound examination of the growth and condition of the fetus can assess the risk of late preeclampsia. This is very important as 75% of preeclampsia cases develop after the 37th week of pregnancy. This makes it possible to more intensively examine women with an increased risk of preeclampsia and to detect the disease in a timely manner, as well as to prepare the baby's lungs for an early birth.

How is preeclampsia screened?

Screening for pre-eclampsia consists of an appointment with a nurse and an ultrasound examination by a gynecologist. The nurse interviews the pregnant woman, measuring her blood pressure, height and weight, and doing a blood test. The gynecologist performs an ultrasound examination and measures the blood flow indices of the uterine arteries feeding the placenta. Based on the blood test values ​​of hormone levels and associated risk factors for preeclampsia, blood pressure parameters, body mass index and uterine arterial blood flow indices, the gynecologist uses a special computer program to assess the individual risk of early or late preeclampsia.

  • The risk of preeclampsia can be assessed in one day.
  • The risk of preeclampsia can also be assessed for women who are expecting twins.

Preeclampsia screening makes you feel safe

Most of the women who participate in preeclampsia screening are at low risk. At increased risk, a three-stage screening test for preeclampsia provides an opportunity, if necessary, to prevent its occurrence or shift it to a later stage of pregnancy. Reducing the risk of pre-eclampsia and careful, evidence-based monitoring of your health and that of your baby gives you the much-needed sense of security. So the child will be able to safely be born when he is ready for this, and you will enjoy a healthy child.
