Where is a duodenal ulcer located?

Generally, duodenal ulcer refers to the presence of an ulcer on the inner lining of the duodenum. A detailed analysis is as follows:

The duodenum is located between the stomach and the small intestine, serving as the entry point where food passes from the stomach into the small intestine during digestion. It is situated in the upper abdomen, primarily below the stomach and in front of the spine. Specifically, the duodenum lies in the right upper quadrant of the abdomen. You can place your hand slightly inward on the upper right side of the abdomen; that area roughly corresponds to the location of the duodenum. However, please note that simply touching this area cannot confirm whether a duodenal ulcer is present—medical examinations are required for accurate diagnosis.

If you suspect you may have a duodenal ulcer, it is recommended to consult a doctor for further evaluation and diagnosis. Physicians can determine the presence of a duodenal ulcer through clinical symptoms, physical examination, laboratory tests, and imaging studies.
