The most common of the symptoms of hyperemesis gravidarum is extreme and persistent nausea that continues after the first trimester of pregnancy. Morning sickness usually ends after the third or fourth month, although some women experience it throughout pregnancy. While it is not necessarily abnormal for morning sickness to continue, it may be one of the signs of hyperemesis gravidarum.
Other symptoms of hyperemesis gravidarum include:
- vomiting after eating or drinking
- vomiting without having eaten
- weight loss
- lightheadedness or fainting
These occurrence and severity of these symptoms varies with each woman, and the experience of one pregnancy does not predict if or to what extent symptoms may appear in later pregnancies. When correctly diagnosed and treated, hyperemesis gravidarum causes no problems for most mothers and babies and symptoms subside after birth.
It is important to not that the signs of hyperemesis gravidarum resemble symptoms of other conditions including hydatidiform mole, which can be serious. Persistent or unusually severe symptoms warrant a thorough examination by an OB/GYN
