Which condition refers to inflammation of the stomach and small intestines, typically causing abdominopelvic pain and diarrhea?

• A. Ulcers
• B. Gastroenteritis
• C. Cholecystitis
• D. Pancreatitis

Answer: (B)

Gastroenteritis is inflammation of the stomach and small intestine, and it commonly presents with abdominopelvic pain and diarrhea. The inflamed mucosa disrupts absorption and increases secretions, leading to loose stools, cramps, and often nausea or vomiting. Infections (viral or bacterial) are frequent triggers and can be accompanied by fever and dehydration.

Ulcers are localized erosions of the stomach or duodenum and tend to cause burning midline or epigastric pain related to meals, not primarily diarrhea. Cholecystitis involves inflammation of the gallbladder and produces right upper quadrant pain, sometimes with fever, but diarrhea is not the defining feature. Pancreatitis involves inflammation of the pancreas with upper abdominal pain that may radiate to the back and can include vomiting; while diarrhea can occur, it’s not the hallmark finding.
