Question: how do you find out if you have a stomach ulcer?
Answer: The only way your doctor can tell for sure if you have an ulcer is to look. She may use a series of X-rays or a test called an endoscopy. This test allows her to pass a thin, bendy tube down your throat and into your stomach and small intestine. The tube has a camera at the end so she can check the lining for ulcers.
