Bleeding caused by hemorrhoids often does not mix with the feces, and the blood is bright red. There may also be blood in the stool, blood dripping, and blood stains on the toilet paper. But we cannot conclude based on these circumstances that blood in the stool is bleeding hemorrhoids. In addition to hemorrhoids, the following diseases can cause blood in the stool

1. Colorectal cancer can cause blood in the stool. Blood in the stool that occurs in the early stages of colorectal cancer may appear as a small amount of blood covering the surface of the stool. As the disease progresses, the amount of blood in the stool will gradually increase, and phenomena such as thinning of the stool and intestinal obstruction may also occur. According to statistics, colorectal cancer is the most common disease causing blood in the stool.

2. Ulcerative colitis can cause blood in the stool. The blood in the stool caused by this disease may be bright or dark in color and is mostly mixed with the feces. There may also be mucus and pus in the stool. Patients with this disease often have symptoms such as abdominal pain and diarrhea.

3. Colorectal polyps can cause blood in the stool. Colorectal polyps can be single or multiple. The characteristics of this disease are that the blood in the stool occurs intermittently, is bright red in color, is not large in quantity, and does not mix with the feces. Some patients have small fleshy masses (polyps) that protrude from the anus during defecation, and then retract into the rectum after defecation.

4. Anal fissure and anal canal mucosal damage can cause blood in the stool. Anal fissure is the most common cause of bloody stools in children. Children with blood in their stools also have symptoms of pain after defecation. Anal fissures in adults are mostly caused by long-term constipation.
