A bowel obstruction is a blockage of the intestines. It can occur in the small or large intestine and has many possible causes. In the United States, the most common reasons for blockage of the large intestine are colorectal cancer and narrowing of the colon from stricture after diverticular disease. Additional causes can be from volvulus (twisting of the intestines) or inflammatory bowel disease.
