What Are The Causes of Black Stool?

Constipation & Colitis

Constipation is the term for infrequent bowel movements. It causes stool to harden in the gut before you pass them. The stool is often devoid of water and may appear black [3] with a hard, pebbly feel. Other signs you have constipation include difficulty executing bowel movements and bloating. Drinking plenty of water, and good nutrition containing fiber can help prevent this condition.

Ulcerative colitis [4] is a type of inflammatory bowel disease that causes ulcers to form in the large intestine. This causes blood to mix with a person’s stool and darken the color. It also causes symptoms like abdominal pain and diarrhea. The cause of this condition is not known, but researchers believe the immune system plays a role. There is no cure for colitis, but treatments can help ease the condition and induce long-term remission.
