Why does pregnancy cause vomiting
Vomiting and morning sickness - NHS
Nausea and vomiting in pregnancy, often known as morning sickness, is very common in early pregnancy.
It can affect you at any time of the day or night or you may feel sick all day long.
Morning sickness is unpleasant, and can significantly affect your day-to-day life. But it usually clears up by weeks 16 to 20 of your pregnancy and does not put your baby at any increased risk.
There is a chance of developing a severe form of pregnancy sickness called hyperemesis gravidarum. This can be serious, and there's a chance you may not get enough fluids in your body (dehydration) or not get enough nutrients from your diet (malnourishment). You may need specialist treatment, sometimes in hospital.
Sometimes urinary tract infections (UTIs) can also cause nausea and vomiting. A UTI usually affects the bladder, but can spread to the kidneys.
Non-urgent advice: Call your midwife, GP or 111 if:
you're vomiting and:
- have very dark-coloured urine or have not had a pee in more than 8 hours
- are unable to keep food or fluids down for 24 hours
- feel severely weak, dizzy or faint when standing up
- have tummy (abdominal) pain
- have a high temperature
- vomit blood
- have lost weight
Treatments for morning sickness
Unfortunately, there's no hard and fast treatment that will work for everyone’s morning sickness. Every pregnancy will be different.
But there are some changes you can make to your diet and daily life to try to ease the symptoms.
If these do not work for you or you're having more severe symptoms, your doctor or midwife might recommend medicine.
Things you can try yourself
If your morning sickness is not too bad, your GP or midwife will initially recommend you try some lifestyle changes:
- get plenty of rest (tiredness can make nausea worse)
- avoid foods or smells that make you feel sick
- eat something like dry toast or a plain biscuit before you get out of bed
- eat small, frequent meals of plain foods that are high in carbohydrate and low in fat (such as bread, rice, crackers and pasta)
- eat cold foods rather than hot ones if the smell of hot meals makes you feel sick
- drink plenty of fluids, such as water (sipping them little and often may help prevent vomiting)
- eat foods or drinks containing ginger – there's some evidence ginger may help reduce nausea and vomiting (check with your pharmacist before taking ginger supplements during pregnancy)
- try acupressure – there's some evidence that putting pressure on your wrist, using a special band or bracelet on your forearm, may help relieve the symptoms

Anti-sickness medicine
If your nausea and vomiting is severe and does not improve after trying the above lifestyle changes, your GP may recommend a short-term course of an anti-sickness medicine, called an antiemetic, that's safe to use in pregnancy.
Often this will be a type of antihistamine, which are usually used to treat allergies but also work as medicines to stop sickness (antiemetic).
Antiemetics will usually be given as tablets for you to swallow.
But if you cannot keep these down, your doctor may suggest an injection or a type of medicine that's inserted into your bottom (suppository).
See your GP if you'd like to talk about getting anti-sickness medication.
Risk factors for morning sickness
It's thought hormonal changes in the first 12 weeks of pregnancy are probably one of the causes of morning sickness.
But you may be more at risk of it if:
- you're having twins or more
- you had severe sickness and vomiting in a previous pregnancy
- you tend to get motion sickness (for example, car sick)
- you have a history of migraine headaches
- morning sickness runs in the family
- you used to feel sick when taking contraceptives containing oestrogen
- it's your first pregnancy
- you're obese (your BMI is 30 or more)
- you're experiencing stress

Causes, Risk Factors, and Treatments
Pregnancy is a beautiful thing. You’ve created life, and in a few months, you’ll have your precious bundle of joy in your arms.
But sometimes it’s not so beautiful. While many expectant mothers walk around with a pregnancy glow and a huge smile on their face, your experience might be less than picturesque — especially if instead of a glow and a smile, you’re developing a close relationship with your toilet since you can’t stop vomiting.
This is supposed to be the happiest time of your life, right? And deep down, maybe it is. But at the same time, nausea and vomiting can make even the most excited parent-to-be struggle to find that happiness.
Understanding the underlying cause of vomiting can keep this problem under control, so read on to learn about common causes of vomiting during pregnancy.
Morning sickness is a common cause of vomiting during pregnancy. But while it’s called morning sickness, nausea and vomiting can actually occur at any time of the day or night.
The exact cause of morning sickness is unknown, but it’s likely due to hormonal changes that wreak havoc on your body. It’s estimated that morning sickness occurs in up to 80 percent of all pregnancies, with nausea and vomiting starting around week six.
The good news is that symptoms typically improve during the second trimester, although some women have morning sickness their entire pregnancy — yikes.
The symptoms of morning sickness include nausea and vomiting. Interestingly, some women don’t even suspect a pregnancy until the first wave of morning sickness hits. After a few days of waking up sick to their stomach, they get a test to confirm or rule out a pregnancy.
But unfortunately, morning sickness isn’t the only thing to worry about during pregnancy, nor is it the only cause of vomiting during this “happy time of your life.”
Some women deal with extreme morning sickness — known as hyperemesis gravidarum — during their pregnancy. It’s likely caused by rising hormone levels.
If you have morning sickness, you may only vomit once a day and can manage nausea and vomiting. If you develop hyperemesis gravidarum, you may vomit more than three or four times a day and feel near-constant nausea.
The vomiting with hyperemesis gravidarum can become so bad that some pregnant women lose weight and risk dehydration due to an inability to keep foods and liquids down.
And if puking all day isn’t bad enough, this condition can also cause dizziness and lightheadedness.
Hyperemesis gravidarum symptoms tend to peak through weeks 9 to 13 and then improve. So symptoms may get better as you move farther along in the pregnancy.
This is a cause of vomiting during pregnancy that some pregnant women don’t expect.
While it’s easy to attribute any type of nausea and vomiting to morning sickness, the problem might actually be due to eating contaminated food during pregnancy.
Anyone is at risk for a foodborne illness, but pregnant women are especially at risk because pregnancy weakens the immune system. And as a result, it becomes harder for your body to fight off bacteria and germs.
Symptoms include those similar to morning sickness, such as nausea and vomiting. But unlike morning sickness, foodborne illnesses can cause other symptoms like headaches, body aches, and even a fever. These symptoms develop shortly after eating contaminated food — maybe within 24 to 48 hours.
The best way to protect yourself is to fully cook meats. Also, refrigerate foods shortly after cooking, wash all fruits and vegetables, and avoid unpasteurized juice, eggs, or milk.
While hormones are likely to blame for morning sickness and hyperemesis gravidarum, certain factors increase the risk of dealing with one or both problems during pregnancy. For example:
- You’re expecting multiples (twins, triplets, or more).
- You have a personal or family history of vomiting during pregnancy.
- You’re sensitive to certain smells or tastes.
- You have a history of migraines.
- You have a history of motion sickness.
The biggest risk for foodborne illness is eating raw, undercooked foods, or fruits and vegetables that haven’t been washed.
Keep in mind that while the above are common causes of vomiting during pregnancy, other problems could arise during a pregnancy that may cause vomiting, too. These include:
- preeclampsia
- gallstones
- ulcers
- appendicitis
- migraine
Run-of-the-mill morning sickness during pregnancy is uncomfortable, but you’re not likely to experience major complications.
But if you develop hyperemesis gravidarum, severe vomiting can lead to dehydration or decreased urination. And if you’re unable to replenish your fluid level, you may need to be hospitalized and receive intravenous (IV) fluids.
This condition can also cause liver damage, a B-vitamin deficiency, and poor growth weight in your developing child, so it’s important to discuss your options with a doctor.
Foodborne illnesses are nothing to play with, either. These illnesses, which can include salmonella poisoning and listeria, can cause premature delivery and even a miscarriage.
It’s also important to note that different types of vomiting can cause different issues. So while morning sickness might not lead to dehydration, hyperemesis gravidarum or a foodborne illness can, depending on the severity of vomiting.
Treatment for vomiting during pregnancy depends on the underlying cause, as well as the severity.
In the case of morning sickness, eating healthy snacks throughout the day like crackers or dry toast may lessen nausea and vomiting. For some women, morning sickness is worse on an empty stomach.
Sometimes, alternative therapies, such as aromatherapy, acupuncture, and acupressure can also provide relief.
Other ways to relieve symptoms include:
- sipping on water or ginger ale
- avoiding triggers, such as certain foods and smells
- taking prenatal vitamins
- using anti-nausea/anti-vomiting medications (if advised by a doctor)
Speak with your doctor before taking any over-the-counter medications.
The same treatments can reduce the intensity of hyperemesis gravidarum. But because vomiting is more severe with this condition, you may need to receive nutrients and fluid through an IV in the hospital.
Your doctor may also prescribe medicine to stop nausea and vomiting. If these medications don’t work, you may need a steroid treatment.
Many foodborne illnesses have to run their course, but you should feel better within a few days. The main goal is to replace lost fluid and avoid dehydration. Eating small meals, sipping on Ginger ale, and drinking water or sports drinks can help you feel better and prevent dehydration.
But you should still speak with your doctor. If you have a foodborne illness caused by bacteria, you may need an antibiotic.
You don’t need a doctor for morning sickness that isn’t severe. Home remedies may be enough to cope with symptoms.
You should, however, call a doctor if you’re vomiting multiple times a day, and if you experience other symptoms like dizziness, a fast heart rate, or if you can’t keep liquids down.
While vomiting during pregnancy can be miserable, it’s also common and usually nothing to worry about. It happens in many pregnancies and doesn’t mean there’s a problem with you or your baby. But if you have any concerns or need reassurance, don’t hesitate to call your doctor.
Early toxemia of pregnancy - causes and treatment
- When does early toxemia begin during pregnancy
- Manifestation of early toxicosis
- Causes of early toxicosis
- Severity of toxicosis during pregnancy
- How to manage morning sickness and relieve symptoms
- 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 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
Oat broth
As an enveloping agent, that is, a substance that forms a mucous film and prevents irritation of receptors on the walls of the stomach and intestines, oat broth is recommended. It is prepared as follows: 2-3 tbsp. spoons of oat grains are washed, pour 500-700 ml of water, boil over low heat under a lid for 30 minutes. The broth is drained, the grains are crushed and poured with new water and boiled until fully cooked. The resulting mass is crushed with a blender.

Take 100 ml of decoction 3 times a day.
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.
Acupressure method is effective for morning sickness and vomiting of pregnant women. To do this, you need to press your finger on a point that is located on the inside of the wrist, in the middle, 3 transverse fingers above the palm.
Aromatherapy

During pregnancy, aroma lamps, aroma medallions, pads - sachets are mainly used. To relieve nausea and vomiting, oils of noble laurel, lemon, lavender, cardamom present, dill, lemon balm, peppermint, anise, eucalyptus, ginger are suitable. 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
Severe (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.
Why do you feel sick during pregnancy in the early stages, at what time can pregnancy be determined.
What helps with nauseaEvery second woman feels sick during pregnancy. An unpleasant symptom appears even before a woman finds out that she is in a position. We tell you why the malaise begins, how many months it lasts and how you can cope with unpleasant symptoms.
What is toxicosis?
Morning (and sometimes afternoon and evening) ailments, along with sore breasts and the absence of menstruation, are considered the main signs by which a woman understands that she is pregnant. But from what day of pregnancy does she start to feel sick? The period at which toxicosis begins varies.
Nearly a third of women experience nausea approximately 4 weeks after the end of their last period. In the remaining 70%, toxicosis occurs at week 8. At the same time, in addition to nausea, half of the women also experience vomiting. In the vast majority of pregnant women, all unpleasant symptoms disappear by the 14th week.
However, in the third trimester, nausea may return. Most often, nausea during pregnancy occurs after eating for a long time.
This is due to the fact that the growing uterus and the child in it begin to squeeze the stomach, which causes a feeling of overeating and nausea. But it also happens that this is a sign of preeclampsia, which must be treated.
Most often, morning sickness and vomiting occur. Unpleasant odors, being in a stuffy room, motion sickness in transport, as a reaction to a certain type of food, and other factors can also provoke an attack. However, discomfort can occur unexpectedly or in cases where everything was normal before.
Among the risk factors that lead to the development of toxicosis are migraines, overweight, endocrine disorders, bronchial asthma, depression, eating disorders, underweight, multiple pregnancy. However, these factors do not mean that a pregnant woman will definitely have toxicosis.
Nausea is not only an unpleasant symptom that overshadows the joy of future motherhood. It can lead to serious consequences. Among them are weight loss, insomnia, fluid and electrolyte imbalance, multiple organ failure, and spontaneous abortion.
Important! Be sure to tell the gynecologist in charge of the pregnancy if any meal causes vomiting, you have begun to lose weight significantly
Causes of toxicosis
Almost every woman is faced with the question of what causes nausea during pregnancy? Several factors play a role in the etiology of toxicosis. What exactly provokes its development in a particular woman is impossible. Among the main reasons are the following:
Factors | Description |
Genetic factors | If the mother had severe nausea, then the daughter may experience the same symptoms. |
immune factors | With nausea and vomiting, the body reacts to antigens that arise in response to foreign genes of the fetus. |
Toxic factors | There is a hypothesis according to which normal excretory processes are disrupted during pregnancy, which causes poisoning. |
Nervous Factors | In women with identified vegetovascular dystrophy and somatotrophic disorders, nausea develops due to dysfunction of the nervous system. |
Psychological factors | Identified depression, neurosis, increased anxiety, eating disorders and other disorders lead to gastrointestinal dysfunction. |
Hormonal factors | A relationship has been found between the level of the hormone hCG and estradiol and the symptoms of toxicosis. It is also confirmed by the fact that the symptoms of toxicosis decrease along with a decrease in the level of these hormones. |
However, it is important to distinguish the symptoms of toxicosis from other diseases. Nausea and vomiting can also be a sign of other illnesses, such as kidney failure or peptic ulcers. Therefore, with severe toxicosis, it is imperative to undergo examinations to exclude other pathologies.
Usually, a general and biochemical blood test, a blood test for infections, ultrasound of the abdominal cavity and urinary system, as well as fibrogastroduodenoscopy and consultations with specialized specialists are prescribed. Treatment and examinations are carried out with care so that it does not harm the child.
Be sure to consult a gastroenterologist, endocrinologist and nephrologist if the symptoms of toxicosis persist after the 14th week of pregnancy, so that this does not lead to dangers for the child. Our doctors will answer all your questions by phone at any time of the day.
What to do in order not to feel sick
You can prevent the development of nausea and toxicosis even during preparation for it. It is necessary to undergo examinations and treat all pathologies found. Particular attention should be paid to diseases that are a risk factor in the development of discomfort.
Another important point is adjusting the diet. In general, it is recommended to give up fried, fatty and spicy foods, as well as start eating often and in small portions. Food should be at room temperature. In addition, it is recommended to drink more.
Plain water and tea can be replaced with mineral water and herbal infusions of mint, lemon balm, chamomile, cranberry and ginger. However, you should not get carried away with herbs, as they may have an impact on the course of pregnancy.
If these methods do not help, the gynecologist may recommend taking antiemetics, vitamin preparations, isotonic solutions, and sedatives. Consultation with a psychologist is also recommended to exclude psychogenic factors.
In severe cases and with signs of exhaustion, the pregnant woman is placed in a hospital where more intensive therapy is carried out. If the woman's condition does not improve, termination of the pregnancy may be recommended as a last resort.
If toxicosis does not cause trouble, it is not treated in any way. They only offer to slightly adjust the diet and try folk methods of dealing with toxicosis. These include a few sips of mineral water, saltine crackers, or a lemon wedge right after waking up.
Case study:
The patient went to the gynecologist with complaints of severe nausea, persistent vomiting and weight loss. The gynecologist did not write off everything for pregnancy and conducted a full examination. FGDS with a biopsy revealed the presence of Helicobacter pylori and signs of gastritis in a woman. After treatment of the underlying disease, the symptoms of toxicosis also decreased.
FAQ
At what time can pregnancy be determined?
+
A blood test for chorionic gonadotropin can show pregnancy as early as 6–8 days after conception. However, it is more reliable to carry it out 3-5 days after the delay or on the 12th day after conception.
How many days after conception does it start to vomit?
+
Nausea can develop from 4 to 7 weeks after the last menstruation, that is, even before the delay appears. Symptoms of toxicosis usually disappear by 12-14 weeks. Also, unpleasant symptoms may return in the third trimester.
What to do if the chest stops hurting during pregnancy?
+
If the chest stops hurting at any stage of pregnancy, this may indicate hormonal disorders in the expectant mother. It can lead to problems with gestation, so any changes in well-being must be reported to the gynecologist.
After how many weeks can you find out about pregnancy?
+
The first signs of pregnancy appear at least 4 weeks after the end of the last menstruation, even before the delay. They will fail in the form of nausea, mood changes, tearfulness. In addition, in the early stages of pregnancy, the breast hurts and enlarges.
How to distinguish toxicosis from ordinary nausea?
+
By external signs, it is almost impossible to distinguish them from each other. But there is a slight difference. Toxicosis usually manifests itself in the morning, and nausea - at any time of the day, including in the evening. If nausea is not complicated by vomiting, but does not go away within a few days, it is recommended to do a home pregnancy test or donate blood for hCG.
Expert opinion
Nausea in the later stages may indicate the development of preeclampsia. This complication affects all organs and leads to the development of severe multiple organ failure. In addition to nausea and vomiting, a pregnant woman is worried about swelling, severe headaches, rapid weight gain, high blood pressure and visual impairment.
Preeclampsia has the most serious consequences for both the mother and the unborn baby. Therefore, if late toxicosis is suspected, a woman is placed under the constant supervision of a doctor in the department of pregnancy pathology.
