Morning sickness

What is it?

Morning sickness is the nausea (upset stomach) and vomiting (throwing up) that may happen during pregnancy. It is most common during the first 3 to 4 months of pregnancy. Most pregnant women have at least mild morning sickness. Although morning sickness is unpleasant, it is harmless unless severe vomiting occurs. The nausea and vomiting is usually gone in the second half of pregnancy.


It is not known why pregnant women have morning sickness. Changes in your hormones and blood sugar may cause the nausea and vomiting. Stress and nerves may make morning sickness worse.

Signs and Symptoms:

Nausea and vomiting usually happens in the morning, often when you first wake up. But morning sickness may happen at any time. Dehydration (d-hi-dra-shun) may happen if you are vomiting too much. This is when you lose too many body fluids. Dizziness, urinating less, dry mouth, and cracked lips may be other signs of dehydration.
