Bright red blood in stool: possible causes

  1. Hemorrhoids: One of the most common causes of bright red blood in stool is hemorrhoids. These swollen blood vessels in the rectum or anus can bleed, especially during bowel movements, resulting in blood appearing on toilet tissue or in the toilet bowl.
  2. Anal Fissures: Anal fissures are small tears or cuts in the lining of the anus, often caused by passing hard stools. They can lead to bleeding during bowel movements.
  3. Diverticulosis: In this condition, small pouches form in the colon wall. If these pouches become inflamed or infected, they may bleed, resulting in blood in the stool.
  4. Gastrointestinal Bleeding: Bleeding can occur anywhere in the gastrointestinal tract, from the esophagus to the rectum. Causes include peptic ulcers, gastritis, esophagitis, inflammatory bowel disease, or tumors.
  5. Colon Polyps: These are growths on the inner lining of the colon or rectum. While most polyps are benign, some may bleed and cause bright red blood in stool.
  6. Colon Cancer: Colorectal cancer can cause bleeding from tumors in the colon or rectum, leading to blood in the stool. Early detection through screening tests is crucial for effective treatment.
  7. Inflammatory Bowel Disease: Conditions such as Crohn’s disease and ulcerative colitis can cause inflammation and ulcers in the digestive tract, leading to bleeding and bloody stools.
  8. Anal Cancer: Although rare, cancer of the anus can cause bleeding and may present as bright red blood in stool.
  9. Rectal Prolapse: This occurs when the rectum protrudes from the anus. It can cause bleeding and may be associated with other symptoms such as constipation or straining during bowel movements.
  10. Intestinal Infections: Certain bacterial, viral, or parasitic infections can lead to inflammation and bleeding in the intestines, resulting in bloody stools.
  11. Medication Side Effects: Some medications, such as aspirin, nonsteroidal anti-inflammatory drugs or blood thinners, can irritate the digestive tract and increase the risk of bleeding.
  12. Trauma: Injury or trauma to the rectal area, such as from vigorous wiping or insertion of objects into the anus, can cause bleeding.
  13. Vascular Malformations: Abnormalities in blood vessels in the digestive tract, such as arteriovenous malformations, may bleed and result in bright red blood in stool.
  14. Coagulation Disorders: Conditions that affect blood clotting, such as hemophilia or von Willebrand disease, can lead to increased bleeding throughout the body, including the gastrointestinal tract.
