Whether or not bright red blood in the toilet can heal on its own needs to be judged on a patient-by-patient basis, where only some patients with mild cases can heal on their own, but most patients cannot. The most common causes of red blood in the toilet are hemorrhoids, anal fissures and polyps. If hemorrhoids are the cause of bright blood in the stool, it usually manifests as blood on paper wipes, dripping blood or jet bleeding after the stool. Some of these patients with mild hemorrhoids who only have symptoms of blood in the stool and no swelling prolapsing around the anus are able to heal themselves after improving their lifestyle habits and resolving constipation, but other patients with more severe hemorrhoids usually cannot heal themselves and require medication or surgery. Some of the patients with anal fissures can heal on their own, but others must be treated to heal. Among patients with rectal polyps, some children with rectal polyps can heal on their own during adolescence, but most patients cannot heal on their own, and there is even the possibility of malignancy if they are not treated for a long time. Therefore, not all bright red toilet stools can be self-healing, it is recommended to go to the anorectal department of the hospital to identify the cause of the blood in order to treat it properly. It is advisable to eat more vegetables and fruits, eat less spicy and stimulating food, and prevent constipation.
