Nausea in Pregnancy
In most cases, the woman bearing a baby doesn’t pay attention to any discomfort. However, some women suffer from nausea throughout 9 months of pregnancy. Pregnancy nausea may appear several times, or may not appear at all.
The experts cannot say exactly when you will have nausea during pregnancy, and whether it will appear at all. It all depends on the woman’s body peculiarities.
Nausea in the First Trimester
Morning sickness is identified as the first sign of pregnancy. It usually starts on the 5th week of pregnancy. Nausea in pregnancy subsides between 13-14 weeks, and if you are bearing twins, nausea may last up to 15-16 weeks.
Nausea in Early Pregnancy: Causes
The fact of experiencing nausea in the early pregnancy has a very simple explanation. The body perceives your future baby as a foreign object that will harm your health, and tries to get rid of it cleansing with vomiting. That means that after the embryo implantation your body tries to expulse it. Your body attempts to get rid of the fetus, but it resists.
Nausea in the early pregnancy can be caused by food, smell of the husband's perfume, shaving foam, the taste of the toothpaste. This is explained by the heightened senses in the pregnant. The nausea cannot be treated, only tolerated.
Norm or Abnormality?
Nausea in the first weeks of pregnancy can occur only in the morning when the stomach is empty, the woman may feel sick throughout the day, but won’t vomit, the nausea may even start the next day. It’s normal to vomit up to five times a day. However, this shouldn’t be accompanied by weakness, dizziness, weight loss. If you have nausea, try to drink many fluids, as it dehydrates your body.
It’s abnormal to have nausea more than 10 times a day, in this case it’s necessary to see the doctor. These are signs of a toxemia. In this case, the vomiting is accompanied by weakness, fatigue, weight loss, fever, high blood pressure. The toxemia is treated in hospital under the doctor’s supervision.
Severe toxemia (severe nausea during pregnancy) is vomiting up to 20 times a day. In this case, the body is very dehydrated, and the woman loses up to 3 kg (6.6 pounds) per week. Severe toxemia is treated strictly under medical supervision.
Second Trimester: Causes of Nausea
Sometimes in the beginning of the 4th month of pregnancy the women may still have nausea. It’s not frightening or dangerous, if the baby is developing normally, the nausea is quite rare and you lack other symptoms. In most cases, during the second trimester nausea may persist, but vomiting has already terminated, because the body "has made up" with the baby. The hormonal peak starts to subside and everything is normalized up to the birth time.
Large amounts of acetone in the blood that the body has accumulated to combat the embryo may cause the persisting nausea. Special medications will help to remove the excess acetone. If the toxemia during the second trimester persists, and still causes you discomfort, be sure to inform your doctor. The doctor may assign you drips that will provide you relief.
Third Trimester: Causes of Nausea
Sometimes nausea subsides in the second trimester and comes back in the third. In this trimester, the pressure that the baby puts on the internal organs causes it. The liver is an especially tender organ, if it’s touched, it causes nausea, heartburn and sometimes pain in the stomach.
At this term, nausea may be the sign of gestosis. This is another name of the late toxemia accompanied by the oxygen deficiency. However, this disease has other symptoms too.
The gestiosis is also characterized by the presence of protein in urine. That is why in the last weeks of pregnancy tests are made every week. Nausea at the 40th week of pregnancy can be a normal manifestation of the late toxemia, as well as testify of the uterine dilatation and the beginning of contractions.
When to See A Doctor?
In any case, you should tell the doctor about your nausea during the routine check-up. He should assess your state and decide whether you need to go to hospital. It is not necessary to contact your doctor separately to report having nausea and vomiting, if your general condition is normal, and vomiting happens no more than 5 times a day.
Pregnant: Nausea and Vomiting During Pregnancy
If the vomiting is observed more than 10 times a day and is accompanied by weakness, dizziness, diarrhea, fever, apathy, you should immediately contact your doctor. In this case, you could even call an ambulance, if it happens on a holiday or a weekend, for example.
Nausea and fever, diarrhea, weakness in the pregnant may be caused by the intoxication during the food poisoning. This can gravely affect the baby’s development. The poisoning requires immediate cleansing with the help of doctors. Only a specialist can determine how to clean your body without causing harm to the baby.
How to Relieve
Nausea during pregnancy usually occurs when the stomach is empty. To avoid this, do not let the body starve, eat small and often. Going to bed take a glass of water and an apple or a cracker with you. Eat them in the morning before you get up, and you won’t have nausea.
Vomiting in the evening during the pregnancy can start, if you have worked a lot, experienced a stress, or, again, have had nothing to eat. So try to be less sensitive to troubles at work, relax during lunch break and have snacks.
Long walks, mineral sparkling water, lemon tea, herbal peppermint, valerian, chamomile, vervain tea can reduce nausea during the pregnancy. To make nausea less frequent, aerate the room where you work and sleep, you need a lot of fresh air.
Your doctor can prescribe you medications from nausea if you have a medium and a high degree of toxemia. You can overcome nausea in the morning having breakfast of products rich in protein (eggs, dairy products, cheese) and in carbohydrates (fruit).
A good remedy for nausea during pregnancy is to avoid oily, hot and spicy food, which provokes vomiting. You also need to avoid everything that makes you feel sick (unpleasant odors, food).

Vomiting and morning sickness in pregnancy
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, and some women feel sick all day long.
Morning sickness is unpleasant, and for some women it can significantly affect their day-to-day life.
But it doesn’t put your baby at any increased risk, and usually clears up by weeks 16 to 20 of your pregnancy.
When to see a doctor for morning sickness
If you’re vomiting and can’t keep any food or drink down, this could be a symptom of a severe form of morning sickness called hyperemesis gravidarum.
This can be serious, and there’s a chance you could become dehydrated or malnourished.
Contact your GP or midwife immediately if you:
- have very dark-coloured urine or don’t pass urine for 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 abdominal (tummy) pain
- have a high temperature (fever) of 38C (100.4F) or above
- vomit blood
- have lost weight
You may need specialist treatment, sometimes in hospital.
Urinary tract infections (UTIs) can also cause nausea and vomiting. A UTI is an infection that usually affects the bladder, but can spread to the kidneys.
If you have any pain when passing urine or you pass any blood, you may have a urine infection. This will need to be treated.
Drink plenty of water to help flush out the bacteria. You should contact your GP within 24 hours.
Treatments for morning sickness
Unfortunately, there’s no hard and fast treatment that will work for every woman’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 don’t work for you or you’re having more severe symptoms, your doctor or midwife might recommend medication.
Things you can try yourself
If your morning sickness isn’t 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
If your nausea and vomiting is severe and doesn’t 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 can’t 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 triplets
- you had severe nausea 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

Nausea and Vomiting During Early Pregnancy

- Introduction to Symptoms During Pregnancy
Up to 80% of pregnant women have nausea and vomiting to some extent. Nausea and vomiting are most common and most severe during the 1st trimester. Although commonly called morning sickness, such symptoms may occur at any time during the day. Symptoms vary from mild to severe.
Hyperemesis gravidarum is a severe, persistent form of pregnancy-related vomiting. Women with hyperemesis gravidarum vomit so much that they lose weight and become dehydrated. Such women may not consume enough food to provide their body with energy. Then the body breaks down fats, resulting in a buildup of waste products (ketones) called ketosis. Ketosis can cause fatigue, bad breath, dizziness, and other symptoms. Women with hyperemesis gravidarum often become so dehydrated that the balance of electrolytes, needed to keep the body functioning normally, is upset (see Overview of Electrolytes).
If women vomit occasionally but gain weight and are not dehydrated, they do not have hyperemesis gravidarum. Morning sickness and hyperemesis gravidarum tend to resolve during the 2nd trimester.
Usually, nausea and vomiting during pregnancy are related to the pregnancy. However, sometimes they result from a disorder unrelated to the pregnancy.
The most common causes of nausea and vomiting are
