Stool prolapse bleeding may be related to hemorrhoids, rectal mucosal damage, chronic diarrhea, intussusception and other factors. 1. Hemorrhoids: If you suffer from hemorrhoids, it can lead to elevated local pressure in the perianal area, impeded blood circulation, aggravated perianal stasis, and damage to the perianal mucosa, which can lead to bleeding in the fecal prolapse. 2. Rectal mucosal damage: If daily eating habits are irregular, overeating, often eat spicy stimulation, high fat, high fat food, will stimulate the intestinal mucosa, the rectal mucosal damage, causing bleeding, in defecation, it will lead to fecal prolapse with blood. 3. Chronic diarrhea: If the gastrointestinal tract peristalsis function is disturbed for a long time, or infected by bacteria, viruses and other pathogenic microorganisms, it can cause chronic diarrhea, which makes the body lose a large amount of water, and the function of perianal sphincter decreases, and when defecation occurs, there is prolapse of anus with bleeding phenomenon. 4. Intussusception: If the intestinal tract is relatively short, when eating and drinking, swallowing a lot of air for a long time, and indigestion after eating and drinking, it will lead to intussusception, causing intestinal spasm, resulting in bleeding from defecation prolapse. If the situation of defecation prolapse bleeding can not be relieved, you should go to the hospital in time for examination and early symptomatic treatment.
