Which description matches Irritable bowel syndrome?

• A. Gastroenteritis
• B. Hemorrhoids
• C. IBS
• D. Appendicitis

Answer: (C)

Irritable bowel syndrome is a functional gastrointestinal disorder defined by recurrent abdominal pain that is associated with changes in bowel habits, without any detectable structural or biochemical disease. This makes the description match IBS because it centers on symptoms—pain and altered stool patterns—without an identifiable organic cause.

Gastroenteritis involves infection with inflammation of the gut and typically presents with acute diarrhea and fever. Hemorrhoids are swollen rectal veins causing bleeding or discomfort but not the chronic, widespread abdominal pain with altered bowel habits seen in IBS. Appendicitis is acute inflammation of the appendix, usually with localized sharp pain, fever, and signs of infection, requiring urgent treatment.
