Pregnancy, nausea: Condition overview
Approximately 6 in 10 pregnant women feel nauseous on a daily basis

If you or someone you know is experiencing nausea during pregnancy, you're not alone. Consumer Reports Health can help with the best research about morning sickness, and expert evidence and advice about treating symptoms.

Key points about nausea and vomiting in early pregnancy
  • It's normal to feel sick to the stomach and throw up during the first few months of pregnancy. Most pregnant women do.
  • Nausea and vomiting won't usually harm you or your unborn baby.
  • If you feel sick to your stomach and throw up when you're pregnant, you are less likely to have a miscarriage than if you don't feel like this
  • You may feel sick to your stomach at any time of the day, not just in the mornings.
  • About 1 in 200 pregnant women have severe nausea and vomiting that can be dangerous to their health and their baby's health. Doctors call this condition hyperemesis gravidarum.
  • Nausea and vomiting usually stop after about 12 weeks of pregnancy. But 1 in 10 pregnant women still have morning sickness after 20 weeks.
Doctors don't know why some women feel sick to the stomach and throw up during pregnancy and others feel fine. They also don't know why one pregnant woman has only mild nausea while another vomits several times a day for many months. However, certain risk factors — such as being pregnant with twins, previous pregnancies with morning sickness, and suffering from migraine headaches — may increase your chances of morning sickness.

Morning sickness can make you feel miserable, but there are both natural remedies and medications you can try. We encourage you to read our entire condition report and to consult with your doctor to learn more about morning sickness. As a Consumer Reports Health subscriber, you’ll have access to our expert research and recommendations, and you’ll be more confident and knowledgeable about which treatments are best for you.
