This blog mainly discusses on the conditions with minor rectal bleeding that occurs intermittently. Rectal bleeding can be caused by various conditions, but even the slightest amount of bleeding should be taken seriously. Common causes of minor bleeding are internal hemorrhoids, ruptured thrombosed external hemorrhoids, fissures, fistula, diverticulosis, colon cancer, colitis, and polyps. Patients of older age or with significant family history of bowel disease or cancer should consider further examination. In addition, patients who were previously treated for rectal bleeding but continued to experience bleeding must be further examined.

The source of minor rectal bleeding is determined by history, physical examination and endoscopies. In the initial office visit, your doctor may inspect the anus visually to look for anal warts, anal fissures, cancer or external hemorrhoids, and followed by the digital examination with a gloved, lubricated finger and then anoscopy to look for abnormalities and sources of bleeding in the lower rectum and anal canal. If indicated, your doctor may also perform endoscopies, either sigmoidoscopy or colonoscopy.
