The doctor will ask about your signs and symptoms and examine you. You may need tests to confirm that you have an H. pylori
infection. You may also need any of the following:
- Endoscopy is used to look for problems in your stomach or duodenum. The doctor will use an endoscope (a tube with a light and a camera on the end) during the procedure and may take a sample from your duodenum to be tested.
- Blood tests may be used to show an infection.
- A breath test may show if H. pylori is causing duodenitis. You will be given a liquid to drink. Then you will breathe into a bag. The doctor will measure the amount of carbon dioxide in your breath. Extra amounts may mean you have an H. pylori infection.
