IBS stands for which condition?

• A. Inflammatory bowel syndrome
• B. Irritable bowel syndrome
• C. Ischemic bowel syndrome
• D. Intestinal bacterial syndrome

Answer: (B)

Irritable bowel syndrome is what IBS stands for. It’s a chronic functional condition of the digestive system characterized by recurrent abdominal pain and changes in bowel habits, such as diarrhea, constipation, or both, without any identifiable organic disease on routine testing. The other terms don’t fit because they refer to different concepts: inflammatory bowel disease (not just “inflammatory bowel syndrome”) describes conditions like Crohn’s and ulcerative colitis and involves physical inflammation; ischemic bowel syndrome involves reduced blood flow to the intestines; and intestinal bacterial syndrome isn’t a recognized medical diagnosis.
