Passing blood during bowel movements accompanied by a tearing pain may be caused by the following conditions: 1. Anal fissure: This is one of the most common causes. An anal fissure occurs when hard stools or excessive straining leads to a partial or full-thickness tear in the skin lining the anal canal. During defecation, this crack may worsen, causing sharp, tearing pain and damaging underlying blood vessels, resulting in rectal bleeding. 2. Hemorrhoids: Especially external or mixed hemorrhoids. When hemorrhoids become aggravated and the surface skin of the hemorrhoidal tissue ruptures, pain and bleeding may occur. 3. Intestinal diseases: Such as colorectal tumors or rectal polyps. Although these conditions rarely cause a tearing sensation directly, they may lead to bleeding due to damage to the intestinal mucosa. 4. Hard stools: Excessively dry stools and excessive straining during bowel movements can aggravate both anal fissures and hemorrhoids, leading to pain and bleeding. Blood in the stool accompanied by a tearing pain during defecation may indicate anorectal conditions such as anal fissures or hemorrhoids. It is recommended to seek timely medical evaluation to determine the exact cause and receive appropriate treatment.
