Bloody stools (usually having red, dark maroon, or black color), blood in the toilet bowl, and blood on the toilet paper are signs of rectal bleeding. The bleeding can be caused by various problems affecting the GI tract, from gastroesophageal reflux disease to anal cancer. More often than not, the cause of rectal bleeding is benign. But rectal bleeding should never be shrugged off as something unimportant, as it may also be a sign of cancer affecting some part of the GI tract.

Below, we list a few possible causes of rectal bleeding and some symptoms that can accompany it.

Causes of rectal bleeding

Possible causes of rectal bleeding include the following:

1. Hemorrhoids

Hemorrhoids are among the most common causes of rectal bleeding. The term describes enlarged blood vessels in the rectum and/or anus which can bleed. Common causes of hemorrhoids include straining when defecating, chronic constipation, and work strain. In some cases, surgery is needed to treat hemorrhoids.

2. Anal fissures

Anal fissures are tears in the lining of the anus. Anal fissures can cause bleeding and severe pain when pooping. The fissures often heal on their own, but, in some cases, medicines (in the form of rectal suppositories or other forms) or surgery is needed to treat them.

3. Gastroesophageal reflux

Gastroesophageal reflux, or simply acid reflux, can also cause blood to appear in stool. Stomach acid that spills into the esophagus can irritate it and cause bleeding.

4. Stomach ulcers

Stomach ulcers can grow and bleed, and the blood will show up in the stool. People with chronic gastritis often develop stomach ulcers.

5. Inflammatory bowel disease

The two types of inflammatory bowel disease (IBD), ulcerative colitis and Crohn's disease, can lead to rectal bleeding. In this conditions, the lining of the GI tract is inflamed and may bleed.

6. Colon polyps

Colon polyps are benign growths that form on the lining of the colon. Polyps that grow large can bleed, causing bloody stools. Benign polyps can become cancerous, this is why they should be removed.
