Which of the following is a characteristic feature of irritable bowel syndrome?
Correct answer
B
Rationale
IBS is characterized by a change in bowel habits, which may include alternating episodes of constipation and diarrhea. Weight loss and malnutrition are not typical; they suggest other conditions like inflammatory bowel disease. Severe rectal bleeding is not associated with IBS but with conditions like hemorrhoids or colorectal cancer. Fever and leukocytosis indicate systemic inflammation, not IBS.
