Hyperemesis gravidarum is best defined as?

• A. Intractable nausea and vomiting during first trimester
• B. Nausea and vomiting with abdominal pain
• C. Nausea and vomiting limited to the first trimester only
• D. Nausea and vomiting throughout pregnancy without weight loss

Answer: (A)

Hyperemesis gravidarum is defined by severe, persistent nausea and vomiting that is difficult to control and can lead to dehydration and weight loss, typically starting in the first trimester. The idea of vomiting being “intractable” highlights how this condition goes beyond ordinary morning sickness and requires more aggressive management. While nausea can occur later, and weight loss is common with hyperemesis, the strongest descriptor in the option is the combination of severity and early pregnancy onset. Abdominal pain is not a defining feature, symptoms aren’t strictly limited to the first trimester in all cases, and vomiting with no weight loss does not fit the usual course of hyperemesis gravidarum.
