Rectal Bleeding


Rectal bleeding can be caused by constipation, hemorrhoids, or anal fissures. It may also be caused by polyps, tumors, or medical conditions, such as colitis or diverticulitis.



  • Pain medicine: You may be given medicine to take away or decrease pain. Do not wait until the pain is severe before you take your medicine.
  • Iron supplement: Iron helps your body make more red blood cells.
  • Steroids: This medicine decreases inflammation in your rectum. It may be applied as a cream, ointment, or lotion.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him of her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your doctor as directed:

Write down your questions so you remember to ask them during your visits.
