Gastroenteritis is defined as inflammation of which regions and typically presents with which symptoms?

• A. Vomiting and diarrhea
• B. Jaundice and pruritus
• C. Constipation and flatulence
• D. Weight gain

Answer: (A)

Gastroenteritis means inflammation of the stomach and intestines, parts of the digestive tract. When this area is inflamed, you typically see rapid onset of vomiting and diarrhea as the body tries to rid itself of infection and as the lining loses its absorptive function. These symptoms are the hallmark of acute gastroenteritis, often with cramps and sometimes fever or dehydration from fluid loss. The other options point to different issues: jaundice and itching suggest liver or bile duct problems; constipation and flatulence aren’t the usual pattern for an acute infectious GI condition; and weight gain isn’t a typical feature of gastroenteritis.
