Stooping pain in the asshole is accompanied by bleeding, which is considered to be caused by anal fissure and hemorrhoids. If the patient has constipation for a long time, the stool is too dry, hard, and difficult to defecate. Excessive force during defecation will tear the skin around the anal canal, resulting in a crack that causes pain and bleeding. Hemorrhoids are caused by varicose veins in the mucous membrane at the end of the anal canal and rectum, and the veins formed by sedimentation appear. When defecating, the hard stool will abrade the capillaries on the surface of the hemorrhoids, causing pain and bleeding. Once blood in stool is found, it is recommended to go to the anorectal department in time, and treat symptomatically after the cause is confirmed to avoid anemia caused by excessive bleeding.
