Tests

Safe and effective tests are available to help your physician diagnose whether or not you have an ulcer. These include:

1. Endoscopy

During an endoscopy, a flexible tube with a light and video camera on the end is gently inserted into your mouth and passed into the stomach and duodenum (upper portion of the intestine). Ulcers in the stomach or duodenum can be seen in real time with the camera during the procedure. Biopsies (tissue samples) can be taken during the endoscopy. This is the most accurate test for ulcers.  

2. Upper Gastrointestinal X-ray

This is a special type of X-ray. To prepare for it, you will be asked to drink barium or a similar substance that outlines the inside of your esophagus (the tube that connects your mouth to your stomach), stomach and duodenum. Ulcers appear as defects in the barium that coats the lining of the stomach or duodenum. This test is not always accurate in showing ulcers, especially in children.
