Rectal Bleeding

Rectal bleeding refers to any blood that passes from your anus, but can also refer to bleeding from your lower colon or rectum. Your rectum makes up the last few inches of your large intestine. Rectal bleeding may show up as blood in your stool, on the toilet paper or in the toilet bowl. Blood that results from rectal bleeding is usually bright red in color, but occasionally can be dark maroon.

Causes of Rectal Bleeding

Common causes of rectal bleeding include the following. But serious causes such as colon cancer can also lead to blood in your stool.

  • Anal fissure (a small tear in the lining of the anal canal)
  • Constipation
  • Hard stools
  • Hemorrhoids (swollen and inflamed veins in your anus or rectum)
  • Diverticulosis

If you have rectal bleeding that lasts more than a day or two, or earlier if the bleeding worries you, request an appointment at San Bernardino Gastroenterology Associates.
