What is a duodenum ulcer?

Intestinal ulcer: The duodenum is the first portion of the small intestine where the stomach empties. It is exposed to stomach acid and is at significant risk of ulcer formation. The 2 most common causes of stomach or duodenal ulcers are infection with the helicobacter pylori bacteria and the use of non-steroidal anti-inflammatory (NSAID) drugs such as aspirin, ibuprofen, naproxen, meloxicam, etc.

A Duodenal Ulcer: is an ulceration not in the stomach (as most are), but rather in the first portion of the small intestine. Although less common than peptic or gastric ulcers, duodenal ulcers are also painful and do carry a risk of bleeding and perforation, just like gastric ulcers. Hope this helps!
