Hyperemesis gravidarum is characterized by which symptom?

• A. Severe and persistent vomiting
• B. Mild nausea only
• C. Weight gain
• D. Abdominal cramps with no vomiting

Answer: (A)

Hyperemesis gravidarum presents with severe, ongoing vomiting that can lead to dehydration, weight loss, and electrolyte disturbances. This makes the most characteristic symptom the intense, persistent vomiting. Normal early-pregnancy nausea is usually milder and doesn’t cause dehydration or weight loss, so the other options don’t fit. Weight gain isn’t typical, and abdominal cramps without vomiting isn’t the hallmark of this condition.
