Introduction[edit | edit source]
Nausea and occasional vomiting are common in early pregnancy (NVP) . It affects 50%-80% of pregnant women during the first half of gestation.[1] When vomiting is severe or protracted, it is often referred to as hyperemesis gravidarum (HG). It is generally referred to as “morning sickness,” for many women symptoms persist over the whole day.HG may effect 0.3–2% of pregnancies and it is defined by dehydration, ketonuria, and more than 5% body weight loss.[2]
