What is morning sickness?
Morning sickness is a condition that causes nausea and vomiting in pregnant women. The nausea can start as early as six weeks into the pregnancy, but typically begins around the fourth week. It usually peaks at around 12 weeks, and goes away by the 20th week of pregnancy.
The exact cause of morning sickness is unknown, but there are several theories. One theory suggests that it’s caused by elevated hormone levels, specifically estrogen and human chorionic gonadotropin (hCG). Another theory suggests that it’s caused by a rise in progesterone levels.
