Inflammatory bowel disease

Inflammatory bowel disease is a group of inflammatory ailments involving the bowel such as Crohn’s disease and ulcerative colitis.

Ulcerative colitis is a non-specific inflammatory response that affects the mucosa and submucosa of the colon. As for Crohn’s disease, it is a granulomatous inflammatory response affecting the entire thickness of the bowel wall. Bleeding diarrhea is likely to occur in ulcerative colitis but can also be an indication of Crohn’s disease.

Ischemic colitis

Individuals older than 60 with bleeding diarrhea might have ischemic colitis. This develops if the flow of blood to a section of the colon is limited or blocked.

The lack of blood to the tissues results to poor oxygen and potential damage and even tissue death. Once the tissues are damaged, they start to leak blood. The contributing factors include congestive heart failure, dehydration, recent surgery and infections.

Polyps or cancer

In uncommon but serious instances, bleeding diarrhea might be a sign of a polyp or colon cancer. A polyp is a mass that form on the colon lining and might oftentimes become cancerous.

Colon cancer is likely to develop among individuals older than 40 especially those who have a family history of the disease.
