Full Definition

Hyperemesis gravidarum is a severe form of pregnancy sickness characterized by persistent nausea and vomiting that leads to dehydration, electrolyte imbalance, and weight loss exceeding 5% of pre-pregnancy weight. Unlike normal morning sickness, this condition typically requires medical intervention and may necessitate hospitalization for intravenous fluid replacement and antiemetic therapy. The condition usually begins in early pregnancy and may persist throughout pregnancy in severe cases. Complications can include Wernicke's encephalopathy from thiamine deficiency and psychological distress.
