Whether blood in the toilet can heal itself needs to be judged according to its cause, because there are many causes of bleeding in the stool, such as the most common hemorrhoids, anal fissures, enteritis, rectal polyps, etc., of which only a small number of patients with mild cases can heal themselves. If the bleeding in the toilet is clearly caused by hemorrhoids, it can heal on its own after improving lifestyle in mild cases without anal swelling prolapse, while patients with more severe hemorrhoids usually need to be treated with external hemorrhoid cream or surgery and cannot heal on their own. The ability of patients with anal fissures to heal on their own depends on the patient’s condition, and some people can heal on their own. Both types of patients often have bright red blood in their stools. Blood from enteritis is usually pus and blood or mucus, etc. Viral enteritis may heal on its own, but bacterial enteritis does not usually heal on its own. Therefore, whether or not blood in the toilet can heal on its own cannot be generalized, but needs to be analyzed on a case-by-case basis, and it is recommended to visit the gastroenterology or anorectal department of a hospital for examination. In daily life, it is recommended that patients with blood in the stool eat more foods rich in fiber and promote defecation, such as bananas and honey water, pay attention to nutritional balance, avoid eating spicy, greasy and rough food.
