Nausea and vomiting are just a few words of pregnancy: they affect 50 to 90% of pregnant women and usually begin during the first weeks of pregnancy. However, there are effective remedies to relieve them. Do not hesitate to try out several of these tips before talking to your doctor.

Where does pregnancy nausea come from?

If they often disappear at the end of the first trimester, they last in 20% of cases until the end of the pregnancy.

In the most severe cases of nausea and vomiting, we speak of hyperemesis gravidarum: continuous vomiting in large quantities disturbs the good nutrition of the mother-to-be. This most acute form affects between 0.3 and 3% of pregnant women.

The causes of pregnancy nausea

Hormonal reasons

The hormonal upheaval associated with pregnancy plays a large part in the onset of nausea and vomiting. During the first 12 weeks of pregnancy, a hormone, commonly called hCG (human chorionic gonadotropin) — the one that is tested for to determine if a woman is pregnant — is suddenly and heavily released. The level of hCG would be directly related to the intensity of nausea. In fact, research shows that women who are most prone to nausea have higher levels of hCG and T4 thyroid hormone.

The rate of release usually stabilizes in the second trimester of pregnancy and nausea often subsides at the same time.

Physical and biological origins

The start of pregnancy is normally full of physical and biological upheavals. The uterus, by changing and enlarging, can compress the diaphragm more or less and thus provoke nausea.

Fatigue experienced during the first few months of pregnancy can also contribute to nausea.

Nausea and vomiting can also occur after infection with a bacteria called Helicobacter pylori and can possibly be worsened by a deficiency of vitamins and in particular vitamin B6.

An overdeveloped sense of smell

During pregnancy, the pregnant woman has an overdeveloped sense of smell. This old mechanism would aim to protect the fetus, very fragile during the first trimester, from possible poisons. Thus, in the old days, women instinctively protected themselves by not eating dishes with an unpleasant smell that might contain spoiled food. Nowadays, this hypersensitivity is the reason why that certain smells like those of perspiration, perfume, exhaust pipes or even cooked food can be very unpleasant for pregnant women and cause nausea.

How to prevent nausea during pregnancy

It is difficult to prevent nausea, but certain actions can decrease its frequency and severity:

  • Avoid going too long without eating. Try to eat more often, but in smaller amounts.
  • Eat lightly (e.g., toast or crackers) and wait 15 minutes before gently getting out of bed in the morning.
  • Eat the foods you crave.
  • Avoid cooking or eating spicy, fatty, or fried foods.
  • Open the windows or use the oven hood to vent any odors that bother you.
  • Get some fresh air and avoid getting too hot.
  • Take naps or take a few days off work if necessary. Fatigue can indeed make nausea worse.
  • If multivitamins make your nausea worse, try taking them with food or just before bed.
  • For some women, psychotherapy may be beneficial in decreasing nausea because it improves stress management and reduces anxiety.

Foods to eat against pregnancy nausea
