Up to 80% of women experience nausea and vomiting of pregnancy (NVP). It usually begins between week four and seven of pregnancy, peaking in the ninth week and in 90% of women resolves by the 20th week. If the onset is after the first trimester other causes must be considered. Hyperemesis Gravidarum (HG) is the severe form of NVP which affects 0.3-3.6% of pregnant women.
