Rectal Pain & Bleeding Q & A

What Causes Rectal Pain?

A long list of possible problems can lead to rectal or anal pain. Inflammatory disease, infections, and minor injuries are some of the top generic causes of rectal pain, while specific conditions include:

  • Hemorrhoids
  • Anal abscess
  • Proctitis
  • Anal prolapse
  • Anal fissure
  • Constipation
  • Crohn’s disease
  • Ulcerative colitis
  • Muscle spasm


Of the possible causes of rectal pain, many can also lead to rectal bleeding, but hemorrhoids and anal fissures are the most likely culprits.

What Causes Rectal Bleeding?

Rectal bleeding causes blood in your stool that may appear bright red, maroon, or cause black, tarry stools. Additionally, you can have rectal bleeding that’s not visible, called occult blood:

  • Bright Red Blood: When you can see obvious, bright red blood, it’s typically caused by hemorrhoids or anal fissures. Internal hemorrhoids occur when veins lining the inside of your anus or lower rectum become inflamed. These veins become enlarged when they’re exposed to pressure from constipation or sitting on the toilet too long. They commonly caused red blood on the toilet paper or in the toilet bowl after a bowel movement. Anal fissures are small tear tears in the tissue lining your anus. They often occur due to hard or large stools, causing pain and bleeding during bowel movements.
  • Maroon Blood, Dark Stools, and Occult Blood: When rectal bleeding is darker in color or causes tarry stool, it originates higher up in your colon or gastrointestinal (GI) tract. Causes of maroon or dark rectal bleeding include proctitis, Crohn’s disease, ulcerative colitis, ischemic colitis, rectal trauma, and rectal ulcers. Black, tarry, foul-smelling stools, called melena, occur when blood is in the colon long enough for bacteria to break it down into chemicals that are black. Melena is a sign that the bleeding began in your upper GI tract, from the small intestine, or an ulcer in the stomach. Bleeding from your rectum or elsewhere in the GI tract can be so slow that you can’t see the tiny traces of blood in your stool. Occult bleeding is often associated with colon polyps and colon cancer.


Does Diverticulosis Cause Rectal Bleeding?

Diverticulosis can cause sudden, heavy rectal bleeding. Diverticula are small sacs in the intestine that bulge out from weak areas in the wall. They may become inflamed and bleed into the intestine. While the bleeding is painless, it can be heavy and cause serious bleeding from your rectum.
