Rectal bleeding is a common problem, often caused by constipation, anal fissures or hemorrhoids. It can be an indication of serious occult disease and should be evaluated by a physician.

Diagnosis and Treatments

A comprehensive evaluation by a physician is necessary to determine the cause of rectal bleeding. Treatment will depend on accompanying symptoms and the diagnosis. Diagnostic studies might include colonoscopy, stool culture, x-rays, blood tests, barium studies, fecal occult blood testing and flexible sigmoidoscopy.

The American Cancer Society recommends the following screening tests after age 50 for colon cancer. Screening should begin at an earlier age if there is a family history of colon cancer:

  • Fecal occult blood testing annually
  • Flexible sigmoidoscopy or barium enema every 5 years
  • Colonoscopy every 10 years

Maintain intestinal health by eating a healthy diet, high in fiber and fresh fruits and vegetables. Drink plenty of fluids and get regular exercise to prevent constipation, hemorrhoids and diverticula.
