Bleeding stools are not necessarily hemorrhoids, there are many other causes, and the diagnosis should be made in conjunction with the color of the bleeding, colonoscopy, stool routine, and clinical symptoms. The cause of hemorrhoids is varicose rectal plexus, which causes bleeding under the friction of stool and has a red color, so bleeding in stool may be hemorrhoids. However, colorectal adenoma, colorectal cancer, colorectal inflammation, and anal fissure can all cause bleeding in the stool, and the cause can mostly be clarified through clinical auxiliary examinations. Among them, colorectal bleeding caused by colitis is mostly pus and blood. In addition, upper gastrointestinal bleeding can also cause bleeding in the stool, which is black in color and called tarry stool. Therefore, there are many causes of bleeding stools, not only hemorrhoids. If you find yourself with bleeding stools, make sure to visit the hospital’s surgery department in a timely manner to clarify the cause before targeted treatment.
