What does hyperemesis gravidarum refer to?

• A. Mild nausea only
• B. Severe persistent nausea and vomiting with weight loss, electrolyte imbalance, ketosis and dehydration
• C. No nausea
• D. Hyperglycemia

Answer: (B)

Hyperemesis gravidarum is characterized by severe, persistent nausea and vomiting during pregnancy accompanied by weight loss, electrolyte imbalance, ketosis, and dehydration. This goes beyond the typical morning sickness, which is usually milder. The other options describe only mild nausea, no nausea, or high blood sugar, none of which define hyperemesis gravidarum.
