Which condition is inflammation and swelling in the intestines, including ulcerative colitis and Crohn's disease?

• A. IBS
• B. Enteritis
• C. Ischemic colitis
• D. Inflammatory bowel disease (IBD)

Answer: (A)

Inflammatory bowel disease describes chronic inflammation of the digestive tract, with ulcerative colitis and Crohn's disease as the classic examples. This group involves ongoing immune-mediated inflammation that leads to swelling and damage in the intestinal walls, producing symptoms like abdominal pain and diarrhea.

Irritable bowel syndrome, by contrast, is a functional disorder without the ongoing inflammation seen in IBD. Enteritis refers to acute inflammation of the intestine, often due to infection, rather than a chronic inflammatory condition. Ischemic colitis arises from reduced blood flow to the colon, causing inflammation as a result of vascular issues rather than autoimmune inflammation.

So the term that best fits ulcerative colitis and Crohn's disease is inflammatory bowel disease.
