The reasons for anal fissures leading to fresh blood in the stool are varied and should be analyzed on a case-by-case basis, with specific treatment as follows: 1. The first thing you need to do is to take care of the symptoms of anal fissures, and the blood in the stool will stop. 2. Adjust your diet: you should develop good habits, eat light, easy-to-digest food, eat more fiber-rich food, eat more vegetables and fruits, don’t eat spicy, stimulating food, develop the habit of having regular bowel movements every day, keep your bowels open, and keep the area around the anus clean and dry. Blood in the stool of patients with anal fissure is caused by bleeding due to fecal stimulation of the fissure during defecation, which is manifested as blood on the stool paper or dripping blood, with little bleeding, sometimes or not, and no heavy bleeding will occur.
