Hyperemesis gravidarum is defined as what?

• A. A mild form of nausea during pregnancy
• B. Hormonal condition unrelated to GI
• C. Severe form of pregnancy-induced nausea and vomiting
• D. A gastrointestinal infection

Answer: (C)

Hyperemesis gravidarum is the severe form of pregnancy-induced nausea and vomiting. It goes beyond the usual morning sickness by causing persistent vomiting that leads to dehydration, electrolyte disturbances, and often weight loss (with possible ketonuria). Because of these metabolic consequences, it can require IV fluids, nutritional support, and sometimes hospitalization. It is not simply mild nausea, not a hormone condition unrelated to GI, and not a GI infection.
