Hyperemesis gravidarum

Hyperemesis gravidarum is a complication of pregnancy caused by high serum levels of β-hCG that is characterized by severe nausea and vomiting such that weight loss and dehydration occurs. Signs and symptoms may include vomiting several times a day and feeling faint. It is more severe than morning sickness. Symptoms usually get better after the 20th week of pregnancy, but may last the entire pregnancy. The condition is also seen in patients with a hydatidiform mole and in multiple gestations. Treatment is with thiamine supplementation, antiemetics, and steroids for severe, intractable hyperemesis.
