Firstly, if there is a history of trauma, it is possible that a foreign body may damage the rectum or the skin of the anal canal, thus leading to the rupture of local blood vessels, which can be clarified through anoscopy, and should be treated with surgery in time, and bleeding sutures can be performed. The second reason for bleeding may be mixed hemorrhoids, especially internal hemorrhoids, which usually show painless blood dripping or spraying, and are easily aggravated when constipated, and can be treated with medication, such as intra-anal hemorrhoid plugs, perianal hemorrhoid cream, and oral hemostatic drugs such as Yunnan Baiyao capsules. If the bleeding does not stop, surgical treatment should be performed in time, such as internal hemorrhoidectomy. Third, anal bleeding may be rectal polyps or rectal adenomas, long-term stimulation in the stool leads to the rupture of the blood vessels under the mucosa, resulting in bleeding, should also be timely polyps and adenomas removed, if necessary, sent for pathological examination. Therefore, the cause of anal bleeding should be clarified, and then active medication or even surgery should be carried out.
