How do you detect ulcers?

1. Endoscopy

- Upper endoscopy: A thin, flexible tube with a camera on the end is inserted into the esophagus to look for ulcers and other irregularities.

2. Biopsy

- This procedure is performed during an endoscopy. Small pieces of tissue are collected from the ulcers and examined under a microscope

3. Upper GI series

- The patient drinks a liquid called barium. This shows up on X-rays so any ulcer craters will not have any of the liquid in there and appear as spots with no barium present..

4. Capsule endoscopy:

- The patient swallows a tiny capsule which has two attached microcameras to provide real-time images as it moves

through the upper gastrointestinal tract.

5. Stool antigen tests

- This blood stool test helps check for small amounts of ulcer blood if there's visible bleeding but isn't conclusive to

confirm or refute ulcers.
