Summary:
- Morning sickness, or nausea and vomiting during pregnancy, is a common experience for many pregnant women. It is estimated that up to 80% of pregnant women experience some degree of morning sickness.
- The exact causes of morning sickness are not fully understood, but it is believed to be related to the rapid hormonal changes that occur during early pregnancy, particularly the rise in human chorionic gonadotropin (hCG) levels.
- While morning sickness can be unpleasant, it is generally considered a sign of a healthy pregnancy and is not associated with any negative outcomes for the baby. In most cases, it resolves on its own by the end of the first trimester.
