How are duodenal ulcers diagnosed?


If a doctor thinks you might have a duodenal ulcer, they will make that diagnosis in one (or more) of four ways.

  • Treatment. In some cases, a doctor will diagnose an ulcer by treating it to see if the symptoms go away.
  • Endoscopy. In this procedure, a doctor will thread a long tube with a camera down a persons throat in order to look into the duodenum and identify any ulcers.
  • X-Ray. Doctors can examine your stomach and duodenum with an x-ray after you have swallowed a barium liquid that coats your stomach to make identifying the ulcer easier.
  • Bacteria Tests. There are a variety of tests that can be done in order to determine whether the bacteria that causes duodenal ulcers is present in the system stool, blood, and breath tests may all be given.
