What is the reason why stool is not formed and bleeding

Hemorrhoids

are varicose veins around the anus, which can affect the discharge of stool and cause stool not to form. In addition, when stool passes, it will also stimulate the surface mucosa of hemorrhoids, resulting in bleeding.

. Inflammatory bowel disease such

as Crohn's disease, ulcerative colitis, etc., the above inflammatory bowel disease may lead to intestinal mucosa damage, and lead to intestinal dysfunction, causing hematochezia and stool not to form.

3. Intestinal space-occupying lesions such

as intestinal polyps, leiomyomas, fibromas, etc., these intestinal space-occupying lesions will hinder the passage of stool, or rupture bleeding, resulting in stool not forming and bleeding.
