When does vomiting stops in pregnancy


Severe vomiting in pregnancy - NHS

Sickness in pregnancy (sometimes called morning sickness) is common. Around 8 out of every 10 pregnant women feel sick (nausea), are sick (vomiting) or both during pregnancy. This does not just happen in the morning.

For most women, this improves or stops completely by around weeks 16 to 20, although for some women it can last longer.

Some pregnant women experience very bad nausea and vomiting. They might be sick many times a day and be unable to keep food or drink down, which can impact on their daily life.

This excessive nausea and vomiting is known as hyperemesis gravidarum (HG), and often needs hospital treatment.

Exactly how many pregnant women get HG is not known as some cases may go unreported, but it's thought to be around 1 to 3 in every 100.

If you are being sick frequently and cannot keep food down, tell your midwife or doctor, or contact the hospital as soon as possible. There is a risk you may become dehydrated, and your midwife or doctor can make sure you get the right treatment.

Symptoms of hyperemesis gravidarum

HG is much worse than the normal nausea and vomiting of pregnancy.

Signs and symptoms of HG include:

  • prolonged and severe nausea and vomiting
  • being dehydrated. Symptoms of dehydration include, feeling thirsty, tired, dizzy or lightheaded, not peeing very much, and having dark yellow and strong-smelling pee
  • weight loss
  • low blood pressure (hypotension) when standing

Unlike regular pregnancy sickness, HG may not get better by 16 to 20 weeks. It may not clear up completely until the baby is born, although some symptoms may improve at around 20 weeks.

See your GP or midwife if you have severe nausea and vomiting. Getting help early can help you avoid dehydration and weight loss.

There are other conditions that can cause nausea and vomiting, and your doctor will need to rule these out first.

See the healthtalk.org website for videos and written interviews of women talking about their experiences of hyperemesis gravidarum and how they coped.

What causes hyperemesis gravidarum?

It's not known what causes HG, or why some women get it and others do not. Some experts believe it is linked to the changing hormones in your body that occur during pregnancy.

There is some evidence that it runs in families, so if you have a mother or sister who has had HG in a pregnancy, you may be more likely to get it yourself.

If you have had HG in a previous pregnancy, you are more likely to get it in your next pregnancy than women who have never had it before, so it's worth planning in advance.

Treating hyperemesis gravidarum

There are medicines that can be used in pregnancy, including the first 12 weeks, to help improve the symptoms of HG. These include anti-sickness (anti-emetic) drugs, vitamins (B6 and B12) and steroids, or combinations of these.

You may need to try different types of medicine until you find what works best for you.

You can visit the Bumps website to find out which medicines are safe to use in pregnancy.

If your nausea and vomiting cannot be controlled, you may need to be admitted to hospital. This is so doctors can assess your condition and give you the right treatment to protect the health of you and your baby.

Treatment can include intravenous fluids, which are given directly into a vein through a drip. If you have severe vomiting, the anti-sickness drugs may also need to be given via a vein or a muscle.

The charity Pregnancy Sickness Support has information and tips on coping with nausea and vomiting, including HG.

Will hyperemesis gravidarum harm my baby?

HG can make you feel very unwell, but it's unlikely to harm your baby if treated effectively.

However, if it causes you to lose weight during pregnancy, there is an increased risk that your baby may be born smaller than expected (have a low birthweight).

Other symptoms you may experience

Pregnancy Sickness Support is in touch with many women who have had HG, and who report having some or all of the following symptoms in addition to the main symptoms listed above: 

  • extremely heightened sense of smell
  • excessive saliva production
  • headaches and constipation from dehydration

If you experience these symptoms, you are not alone. Many women have them and they will go away when the HG stops or the baby is born.

How you might feel

The nausea and vomiting of HG can impact your life at a time when you were expecting to be enjoying pregnancy and looking forward to the birth of your baby.

It can affect you both emotionally and physically. The symptoms can be hard to cope with. Without treatment HG may also lead to further health complications, such as depression or tears in your oesophagus.

Severe sickness can be exhausting and stop you doing everyday tasks, such as going to work or even getting out of bed.

In addition to feeling very unwell and tired, you might also feel:

  • anxious about going out or being too far from home in case you need to vomit
  • isolated because you do not know anyone who understands what it's like to have HG
  • confused as to why this is happening to you
  • unsure about how to cope with the rest of the pregnancy if you continue to feel very ill

If you feel any of these, do not keep it to yourself. Talk to your midwife or doctor, and explain the impact HG is having on your life and how it is making you feel. You could also talk to your partner, family and friends if you want to.

If you want to talk to someone who has been through HG, you can contact Pregnancy Sickness Support's help section. They have a support network across the UK and can put you in touch with someone who has had HG.

Bear in mind that HG is much worse than regular pregnancy sickness. It is not the result of anything you have or have not done, and you do need treatment and support.

Another pregnancy

If you have had HG before, it's likely you will get it again in another pregnancy.

If you decide on another pregnancy, it can help to plan ahead, such as arranging child care so you can get plenty of rest.

You could try doing things that helped last time.

Talk to your doctor about starting medicine early.

Blood clots and hyperemesis gravidarum

Because HG can cause dehydration, there's also an increased risk of having a blood clot (deep vein thrombosis), although this is rare. 

If you are dehydrated and immobile, there is treatment that you can be given to prevent blood clots.

Severe Morning Sickness (Hyperemesis Gravidarum) (for Parents)

What's Morning Sickness?

During the first trimester of pregnancy, many women have the bouts of nausea and vomiting known as morning sickness.

Despite its name, morning sickness can happen day or night. It usually starts around the 6th week of pregnancy, is at its worst around week 9, and stops by weeks 16 to 18. Although unpleasant, morning sickness is considered a normal part of a healthy pregnancy.

What’s Severe Morning Sickness?

Severe morning sickness is when nausea and vomiting get so serious that a pregnant woman vomits several times a day, loses weight, and gets dehydrated or is at risk for dehydration.

If this rare pregnancy-related condition isn’t treated, it can affect a woman's health and her baby's ability to thrive.

The medical term for severe morning sickness is "hyperemesis gravidarum" (hi-per-EM-eh-sis grav-ih-DARE-um), which means "excessive vomiting during pregnancy." It usually follows a similar timeline to normal morning sickness. But it can go longer, sometimes lasting for the whole pregnancy. Often, the symptoms get less severe as the pregnancy continues.

Most cases of hyperemesis gravidarum affect a woman's first pregnancy. But women who have it in one pregnancy are more likely to have it in future pregnancies.

What Causes Severe Morning Sickness?

The cause of severe morning sickness isn’t known. But it might be related to the hormone changes of pregnancy. A hormone called human chorionic gonadotropin, or HCG, might be to blame because severe morning sickness most often happens when HCG levels are at their highest in a pregnant woman's body.

Severe morning sickness also might run in families. It’s more common in women whose close family members (such as mothers and sisters) have had it.

Other things that can increase a woman's chances of having severe morning sickness include:

  • carrying multiples (twins, triplets, etc.)
  • history of motion sickness
  • migraine headaches with nausea or vomiting

What Problems Can Happen?

The nausea and vomiting that happen in severe morning sickness are so extreme that they can harm the mother and the baby. Not being able to keep down food makes it hard for the mom to meet her nutritional needs. So she might lose weight. And a loss of fluids, combined with the loss of stomach acid from vomiting, can cause dehydration and electrolyte imbalances.

If severe morning sickness isn’t treated, it can cause many problems, including organ failure and the early birth of her baby.

When Should I Call the Doctor?

Call the doctor right away if you’re pregnant and have any of these symptoms:

  • nausea that lasts throughout the day, making it impossible to eat or drink
  • vomiting three to four times per day or not being to keep anything in the stomach
  • brownish vomit or vomit with blood or streaks of blood in it
  • weight loss
  • fainting or dizziness
  • peeing less than usual
  • a fast heart rate
  • a lot of headaches
  • unpleasant, fruity mouth or body odor
  • extreme tiredness
  • confusion

How Is Severe Morning Sickness Treated?

Treatments used for morning sickness, such as eating dry crackers in the morning or a bland diet, may be recommended for women with extreme morning sickness. But these might not help with severe symptoms.

Medical treatment can include:

  • a short period of not eating to rest the gastrointestinal system
  • intravenous (IV) fluids
  • vitamin and nutritional supplements

Some women might get medicine to stop the vomiting, either by mouth or through an IV. The doctor might recommend eating foods with ginger or taking vitamin B6 supplements to help ease nausea. It can also help to:

  • Eat a bland diet.
  • Eat frequent small meals.
  • Drink plenty of liquids when not feeling nauseated.
  • Avoid spicy and fatty foods.
  • Eat high-protein snacks.
  • Avoid sensory stimuli that can act as triggers (like specific smells or noises).

If a woman feels anxious or depressed about her condition, talking to a therapist or counselor might help her cope with her feelings.

What Else Should I Know?

With treatment, women with severe morning sickness can feel better and get the nourishment they need so they and their babies thrive. And lifestyle changes can help ease nausea and vomiting and make the pregnancy more enjoyable.

With time, symptoms usually do improve. And, of course, they stop by the time a woman's next journey starts: parenthood.

Early toxemia of pregnancy - causes and treatment

  1. When does early toxemia begin during pregnancy
  2. Manifestation of early toxicosis
  3. Causes of early toxicosis
  4. Severity of toxicosis during pregnancy
  5. How to manage morning sickness and relieve symptoms
  6. Principles of treatment of early toxicosis

Most women, having barely learned about the onset of pregnancy, expect to feel unwell, bouts of nausea and even vomiting. Indeed, early toxicosis often becomes a constant companion of many expectant mothers in the early stages of pregnancy. Is there any way to alleviate these unpleasant symptoms?

Toxicosis (and doctors call this condition gestosis) is a syndrome that is defined as a violation of a woman's adaptation to pregnancy. According to the time of occurrence, early preeclampsia is distinguished, which will be discussed in this article, and late preeclampsia, which appears in the last 2-3 months of pregnancy and is manifested by edema, increased blood pressure and the appearance of protein in the urine.

When early morning sickness begins in pregnancy

Early morning sickness usually occurs in the first half of pregnancy. As a rule, after the end of the formation of the placenta, that is, at 12-13 weeks of pregnancy, the phenomena of toxicosis stop. During a normal pregnancy, adaptive changes in the function of almost all organs and systems occur in a woman's body, which are regulated by the nervous system with the participation of endocrine glands. Toxicosis also occurs due to the impossibility of the adaptive mechanisms of the body of the expectant mother to adequately meet the needs of the developing fetus.

Manifestation of early toxicosis

The most common manifestation of toxicosis is vomiting. Other forms of early toxicosis are very rare:

  • pregnancy dermatosis is a group of skin diseases that occur during pregnancy and disappear after it. When it occurs in early pregnancy, dermatosis is caused by immune disorders in the body of a pregnant woman, and is also most often found in patients with diseases of the digestive and endocrine systems. The most common form of dermatoses of pregnancy is pruritus gravidarum, which can be on a small area of ​​the skin or spread throughout the body, including the feet and palms.
  • tetany (chorea) of pregnant women. This condition occurs when the function of the parathyroid glands decreases, as a result of which calcium metabolism in the body is disturbed. Clinically, the disease is manifested by muscle cramps, more often cramps occur in the fingers, sometimes in the muscles of the face.
  • salivation - increased secretion of saliva, in connection with which there is a large loss of fluid (up to 1 liter per day). Salivation can be an independent manifestation of toxicosis or accompany vomiting of pregnant women. In the development of salivation, not only changes in the central nervous system are important, but also local disturbances in the salivary glands and their ducts under the influence of hormonal changes.
  • Pregnancy bronchial asthma is an extremely rare form of preeclampsia.
  • osteomalacia of pregnancy - softening of the bones due to a violation of the metabolism of calcium and phosphorus, while the bones of the pelvis and spine are more often affected
  • neuropathy and psychopathy of pregnant women.

Causes of toxicosis in the early stages

There are many theories trying to explain the causes and mechanisms of development of early toxicosis: the most recognized are the so-called neuro-reflex and immunological.

According to the neuro-reflex concept , vomiting occurs as a result of a violation of the relationship between the cerebral cortex and subcortical structures. During pregnancy, the subcortical centers of the brain begin to work more intensively than usual, which are responsible for most protective reflexes, including breathing and cardiac activity. In the same areas of the subcortical structures are the vomiting and salivary centers, the nuclei of the olfactory system of the brain. Excitation processes also capture them. Therefore, nausea and vomiting may be preceded by such phenomena as deepening of breathing, increased heart rate, an increase in the amount of saliva, pallor due to vasospasm, and a change in smell.

Immunological disorders play a certain role in the development of preeclampsia . The timing of the onset of vomiting usually coincides with the formation of blood circulation in the placenta, increased reproduction of white blood cells - lymphocytes, which are involved in immune reactions. The fetus is foreign to the mother's body, and her immune system reacts to it in this way. After the full maturation of the placenta, which accumulates all these immune cells, toxicosis usually disappears.

Human chorionic gonadotropin (hCG) plays a certain role in the development of vomiting during pregnancy. This hormone is produced by the placenta during pregnancy. Its high concentration can provoke vomiting.

The severity of toxicosis during pregnancy

The main symptom of early toxicosis of pregnant women is vomiting. Depending on the frequency of its occurrence, as well as the degree of metabolic disorders in the body of the expectant mother, doctors distinguish three degrees of severity of vomiting during pregnancy.

How to manage morning sickness and relieve symptoms

Treatment for mild morning sickness is usually done at home. But, nevertheless, a pregnant woman should be under the supervision of doctors, take all the tests recommended by the doctor, and follow the appointments. This will allow the doctor to monitor the condition of the future mother's body and prevent possible complications in time. A woman needs to organize a normal sleep and rest regimen, walks in the fresh air, a calm atmosphere in the family are shown.

Proper nutrition

You need to eat in small portions, fractionally, every 2-3 hours. Food should be easily digestible, high-calorie and fortified whenever possible. In connection with a decrease in appetite, they recommend varied and pleasant food for the expectant mother, that is, products are selected taking into account the desires of the pregnant woman, with the exception of spicy dishes and smoked meats. It is important to remember that very hot or very cold food often induces vomiting, so the dishes should be warm. Reception of alkaline mineral waters in small volumes 5-6 times a day is shown.

If nausea and vomiting occur in the morning, immediately after waking up, it is recommended to have breakfast while lying in bed without getting up. For breakfast, you can eat dry crackers, crackers, drink tea or water with lemon, light yogurt is allowed. It is better to put all this next to the bed in advance or ask someone to bring breakfast.

Every woman chooses for herself a remedy that helps to fight nausea. Someone helps a slice of orange, lemon or apple, some expectant mothers carry crackers or mint sweets with them to alleviate the symptoms of toxicosis. Pumpkin juice has a good antiemetic effect. Many pregnant women benefit from ginger tea. It is prepared very simply:

ginger root finely chopped or grated on a coarse grater is poured with boiling water and infused for 15-20 minutes. Tea can be drunk warm or chilled, adding lemon, mint or honey to it.

Fats and proteins of animal origin are recommended to be consumed in the morning, when pancreatic enzymes are more active. Dairy products are best eaten after dinner or before bed.

Do not use food with preservatives, broiler meat, fast food, fast food.

To maintain metabolic processes in the body, it is advisable to drink 2-2.5 liters of fluid per day. With increased vomiting, it is not recommended to consume solid and liquid food at the same time. Liquids should not be drunk 30 minutes before and within 1.5 hours after eating, as this provokes vomiting by stretching the walls of the stomach and affecting the receptors.

Decoctions and infusions

Therapeutic exercise

Among non-drug treatments, exercise therapy has a good effect. The complex of exercises includes walking, deep breathing with stretching of the muscles of the trunk and limbs. It is necessary to exclude inclinations, they can increase nausea. The complex includes dynamic exercises for training the muscles of the arms, legs, relaxation exercises. Remedial gymnastics also includes training in breathing techniques. As a result, the body is saturated with oxygen, the excitability of the vomiting center decreases - toxicosis is relieved.

Physiotherapeutic procedures

Physiotherapeutic procedures for the treatment of early toxicosis include electrosleep, acupuncture, laser therapy . Electrosleep is a method that uses low frequency currents to induce sleep. The duration of the procedure is from 60 to 90 minutes, the course of treatment is 6-8 sessions.

Laser therapy

In the complex therapy of early toxicosis, blood is irradiated with a helium-neon laser through a light guide passed through a needle placed in the cubital vein. The procedure lasts 15-20 minutes. The therapeutic effect is achieved due to the influence of the laser on blood cells, changes in its properties, accumulation of biologically active substances in the blood. As a result, the metabolism in cells changes, the resistance of tissues and the body to adverse conditions increases, and the vitality increases.

Acupuncture, acupuncture

Treatment methods based on stimulation of biologically active points and zones on the body and face. With early toxicosis, such an effect changes the tone of the nervous system of a pregnant woman. A session of acupuncture is carried out 1-2 times a week and lasts 15-30 minutes.

To flavor the air, you can use the following mixture 0 3 drops of lavender oil, 1 drop of peppermint oil, 1 drop of eucalyptus oil.

Principles of treatment of early toxicosis

Even with a mild course of early toxicosis of pregnant women, the attending physician will definitely prescribe a number of tests - a general blood test, a general urinalysis, a biochemical blood test, a hemostasiogram. This is necessary to control the condition of a pregnant woman and to timely prescribe medications to correct the changes that occur in the body.

If non-drug remedies are ineffective, the doctor prescribes medications that help fight toxicosis. First of all, these are herbal sedatives, homeopathic medicines for nausea, vitamin B6 preparations, antiemetics.

If, despite all the therapy, vomiting increases, the doctor detects changes in blood and urine tests, and body weight continues to progressively decrease, hospitalization is indicated.

An intravenous infusion of medicines is carried out in the hospital, which restores the fluid, microelements and proteins lost by the body. A pregnant woman receives at least 2-2. 5 liters of fluid intravenously per day.

To improve blood flow through the placenta and improve oxygen supply to the fetus, oxygen therapy can be prescribed - inhalation of an oxygen-air mixture for 20-30 minutes twice a day.

Most often, the effects of toxicosis gradually decrease by 12-13 weeks of pregnancy.

Mild

Mild vomiting on an empty stomach or after meals occurs 3 to 5 times a day. Despite vomiting, part of the food is still retained and significant weight loss is not observed in such pregnant women. The general condition does not suffer significantly, there are no changes in blood and urine tests. Such vomiting is easily treatable with various non-drug means, and often resolves on its own after the normalization of the diet and rest.

Moderate vomiting

Moderate vomiting (or moderate vomiting) is expressed in the increase in vomiting up to 10 times a day, regardless of food intake. Characterized by persistent nausea. There comes dehydration of the body, a decrease in body weight by 3-5 kg ​​(6% of the initial weight). The general condition of pregnant women worsens. Expectant mothers complain of weakness, apathy, tearfulness, sometimes depression. The skin is pale, dry, the tongue is covered with a white coating, yellowness of the skin may be noted.

Excessive vomiting

The severe form (excessive pregnancy vomiting) is rare. The frequency of vomiting up to 20 times a day or more. Excessive vomiting is characterized by severe dehydration and intoxication. This condition can occur as a continuation of moderate vomiting of pregnant women or initially acquire a severe character. With excessive vomiting, body weight decreases rapidly, on average by 2-3 kg per week, the skin becomes dry and flabby, subcutaneous fat quickly disappears, the tongue and lips are dry, there is a smell of acetone from the mouth, body temperature can rise up to 38 degrees. Vomiting of moderate and severe degrees is treated in a hospital.

When early morning sickness begins and how to deal with it during pregnancy

Early morning sickness of pregnancy is a condition that causes a lot of suffering for a woman. Some feel "trick" even before the delay, while for others it all starts from 5-6 weeks. Obstetrician-gynecologist Galina Vladimirovna Ovsyannikova talks about the causes of toxicosis and ways to alleviate it.

Symptoms of toxicosis

Eating habits change drastically, hypersensitivity to odors, nausea, irritability appear, constantly wanting to sleep.
Rarely appear uncontrollable salivation, subfebrile temperature, vomiting.

This condition usually takes the woman by surprise. After all, she needs to continue working, taking care of her family, she has a lot of things planned. With this, she goes to the doctor, already pretty tired and with a sad look. And we're starting to figure it out.

First of all not everyone suffers from toxicosis. Some simply eat everything and do not gain weight, or even lose weight, and this manifests their toxicosis. These women are lucky. Although they also manage to worry about this, as they have heard enough "as it should be" from their friends.

Secondly, the severity of toxicosis depends on the state of the nervous system, lifestyle and "similarity" of the baby to his mother in terms of protein composition.

And more about that.

Toxicosis: why and for what?

  • Nervous system. It has been noticed that toxicosis is most pronounced in anxious women, leaders, doctors, teachers, that is, people with increased nervous stress. And, by the way, note that animals do not have such toxicosis as humans do. They do not take on "the entire world responsibility" and therefore they do not feel sick or vomit. At most, females sleep a lot and retire to save energy.
  • Lifestyle. If a woman enters pregnancy not in a resource state, tired, exhausted, slagged from poor nutrition and lack of water, and even after some kind of illness, poisoning, herpetic manifestation, SARS, then the body will try to "put the woman to bed" in order to sleep, rest, gain strength, eat different foods to replenish supplies. Everything is logical. This is a smart move in the fight for survival.
  • Any person has a unique genetic code, which is laid already at the moment of fertilization. And how different it will be from the mother's code, toxicosis will be so pronounced. To make it clearer, there are people who are so similar in this code, protein composition, that their organs can be transplanted to each other and they will take root. And others, on the contrary, are not at all similar, and if, for example, a kidney is transplanted from such a person, then it will be rejected. Also here. If a child has inherited a similar genetic code, then intoxication from getting his protein into the mother's blood will be less. And vice versa. As pregnancy progresses and the placenta forms between the body of the mother and child, a placental barrier is formed. And toxicosis decreases: therefore, in most women, it disappears by the 12th week.

How to survive?

There are no common recipes for all: we are all different and each has its own reason for toxicosis. But still there are rules that help most women:
