What is an ulcer?

An ulcer is a hole in the wall of the esophagus, stomach, small bowel, or colon; the hole goes all the way through the lining tissue layer of the organ and possibly deeper. If the hole is shallower than that and only goes part of the way through the lining tissue layer, it is called an erosion. Erosions and ulcers may bleed. Ulcers may cause pain and may even burrow through the entire wall of the organ, but erosions do not. Erosions and ulcers may occur singly or in groups.
