Background. More than half of pregnant women suffer from nausea and vomiting, which typically begins by the fourth week and disappears by the 16th week of pregnancy. In 1 in 200 women, the condition progresses to hyperemesis gravidarum (HG). The cause of nausea and vomiting in pregnancy is unknown, but may be due to the rise in human chorionic gonadotrophin concentration, neuromuscular factors. Therefore, treatment may be difficult because are the full effect of possible treatment on the fetus is not known. This article reviews the epidemiology, risk factors, diagnosis and various treatments for NVP.
Aim.To review the risk factors for nausea and vomiting during pregnancy, diagnosis, possible treatments, their safety.
