Rectal cancer: mainly caused by environment, heredity, chronic colorectal inflammation and other factors, the earliest symptom is the change of defecation habit and fecal character, and the patients mostly show increased frequency of defecation, diarrhea, constipation, bloody stools, etc., and the shape of fecal matter becomes thin, flattened or leaf-shaped. The shape of stool will be different depending on the size and shape of the tumor.
3. Hemorrhoids: If the hemorrhoids are small, the shape of stool is usually no different from normal, when the hemorrhoids are large and form thrombus, it may lead to the change of stool shape; furthermore, the formation of scar tissue after hemorrhoid surgery causes anal stenosis, and the shape of stool will also be changed. In patients with anal stenosis, the stool may be thin stripes or flat, and sometimes it may be shaped like a leaf.
