Blood on toilet paper after defecation may be caused by hemorrhoids, but it cannot be ruled out that it is caused by anal fissure, rectal polyps, and other diseases. It is recommended that patients seek medical attention promptly and receive targeted treatment after clarifying the cause. 1. Hemorrhoids: If patients consume spicy and stimulating foods for a long time or sit for a long time, it may lead to varicose veins in the anus, thereby inducing hemorrhoids. During the illness, patients may experience pain during bowel movements, anal itching, and even bleeding. At this time, patients can use musk hemorrhoid ointment, compound carrageenate ointment, and other drugs for treatment under the guidance of a doctor. Surgical removal can also be used to improve the condition. 2. Anal Fissure: If one does not pay attention to dietary health and often eats spicy foods like chili, it can damage the anal canal skin, causing difficulty in bowel movements. With the progression of the disease, pain symptoms may also occur. At this time, patients can use warm water sitz baths for treatment and also use nitroglycerin ointment, erythromycin ointment, and other drugs for treatment under the guidance of a doctor. 3. Rectal Polyps: It may be caused by familial inheritance or repeated irritation of intestinal inflammation. It can compress the surrounding tissues and organs to a certain extent, causing abdominal pain. If not treated promptly and effectively, it can also be accompanied by bleeding in the stool. In this case, treatment methods such as endoscopic electrocoagulation can be used. In addition, it cannot be ruled out that it is related to colitis, ulcerative colitis, and other reasons. If the patient's symptoms are severe, it is recommended to seek medical attention promptly.
