Minor Rectal Bleeding

Tears that occur in the lining of the anus are called anal fissures. This condition is most commonly caused by constipation and passing hard stools, although it may also result from diarrhea or inflammation in the anus. In addition to causing bleeding from the rectum, anal fissures may also cause a lot of pain during and immediately after bowel movements. Most fissures are treated successfully with simple remedies such as fiber supplements, stool softeners (if constipation is the cause) and warm baths. Your doctor may also prescribe a cream to soothe the inflamed area. Other options for fissures that do not heal with medication include treatment to relax the muscles around the anus (sphincters) or surgery.

Proctitis refers to inflammation of the lining of the rectum. It can be caused by previous radiation therapy for various cancers, medications, infections or a limited form of inflammatory bowel disease (IBD). It may cause the sensation that you didn’t completely empty your bowels after a bowel movement, and may give you the frequent urge to have a bowel movement. Other symptoms include passing mucus through the rectum, rectal bleeding and pain in the area of the anus and rectum. Treatment for proctitis depends on the cause. Your doctor will discuss the appropriate course of action with you.

Polyps are benign growths within the lining of the large bowel. Although most do not cause symptoms, some polyps located in the lower colon and rectum may cause minor bleeding. It is important to remove these polyps because some of them may later turn into colon cancer if left untreated.

Colon cancer refers to cancer that starts in the large intestine. It can affect both men and women of all ethnic backgrounds and is the second most common cause of cancer deaths in the United States. Fortunately, it is generally a slow-growing cancer that can be cured if detected early. Most colon cancers develop from colon polyps over a period of several years. Therefore, removing colon polyps reduces the risk for colon cancer. Anal cancer is less common but curable when diagnosed early.

Solitary rectal ulcer syndrome is an uncommon condition that can affect both men and women, and is associated with long-standing constipation and prolonged straining during bowel movement. In this condition, an area in the rectum (typically in the form of a single ulcer) leads to passing blood and mucus from the rectum. Treatment involves fiber supplements to relieve constipation. For those with significant symptoms, surgery may be required.
