Dr. Li Jingxiang
Pain and bleeding during bowel movements may be caused by various factors. Anal fissures are a common cause; when the skin around the anus tears due to various reasons—such as chronic constipation or hard, dry stools—severe pain and bright red blood may occur during defecation. Hemorrhoids can also lead to these symptoms, especially external or mixed hemorrhoids, which may cause pain along with bright red bleeding. Other conditions such as rectal polyps, colorectal cancer, and ulcerative colitis may also result in anal pain and bleeding. These diseases differ in both symptoms and underlying causes, and timely medical evaluation is necessary for accurate diagnosis and treatment. Maintaining healthy dietary and bowel habits in daily life can help prevent the development of these conditions. Individuals with concerns should seek prompt medical advice.
