What causes blood in men’s stool?

1. Internal hemorrhoids: Blood in the stool is the main symptom of internal hemorrhoids. The blood is bright red and appears in dripping or spurting form. It often occurs during defecation, mainly due to rupture of varicose veins.

2. Anal fissure: The blood is bright red and can be seen by dripping or wiping with toilet paper. Fresh anal fissures will cause severe anal pain after defecation.

3. Rectal polyps: Rectal polyps are more common in children with bloody stools. The blood is fresh and covers the surface of the stool without mixing with it. It is often accompanied by symptoms such as prolapse and tenesmus.

4. Chronic proctitis or ulcerative proctitis: The main symptoms of the patient are anal bloating, incomplete defecation, unformed stool, accompanied by dark red bloody stool or mucous bloody stool. Microscopic examination may reveal pus cells. If it is amebic or bacillary dysentery, trophozoites or Shigella dysenteriae can be found to confirm the diagnosis.

5. Rectal cancer: The bloody stool caused by rectal cancer is characterized by dark red blood, often mixed with mucus attached to the surface of the stool, and often accompanied by symptoms such as increased frequency of bowel movements and a feeling of anal prolapse. Therefore, male patients with bloody stools should first rule out rectal cancer.
