Diseases of the Colon and Rectum

Visit our Colon and Rectum page.

Anal Stenosis

Anal stenosis is when the anal opening is too small, or that it does not relax or open properly. This may need to be treated with surgery that brings a flap of skin down to enlarge the anal opening. Read more

Colonic Inertia

Colonic inertia is where the muscles or nerves in the colon fail to operate normally. This prevents feces from exiting through the rectum and can lead to constipation. Read more

Colorectal Cancer

Colorectal cancer forms in the mucosa lining of the bowel and can cause a number of bowel symptoms depending on the position of the cancer. A physician will need to perform a number of tests to determine the appropriate diagnosis. Read more

Crohn's Disease/Ulcerative Colitis

Crohn's Disease is a form of colitis that affects the gastrointestinal tract from the mouth to the anus. It occurs most commonly in the lower part of the small intestine and colon. Ulcerative Colitis causes inflammation only in the mucosal lining of the colon and does not affect the small intestine or the stomach. Read more


Diverticulosis is when small sacs or pouches form in the wall of the colon. The sacs are caused by high pressures within the colon and can occur when there is enough fiber in the bowel movement. Diverticulitis is an inflammation of these sacs due to infection that causes pain or tenderness to the touch. Read more
