Hyperemesis Gravidarum

Overview :

In pregnant women, nausea and vomiting (morning sickness) are common, affecting up to 80% of pregnancies. Hyperemesis, or extreme nausea and excessive vomiting, occur in about 1% of pregnancies. This condition causes uncontrollable vomiting, severe dehydration, and weight loss for the mother. However, hyperemesis gravidarum rarely causes problems for the unborn baby.
