Diagnosis of a Peptic Ulcer

A peptic ulcer is an open sore on the lining of the stomach, esophagus or upper small intestine. In the stomach it is called a gastric ulcer. In the small intestine it is called a duodenal ulcer. Peptic ulcers can be caused by a bacterial infection.

  1. Symptoms

    • Symptoms of peptic ulcers include burning pain between the breastbone and naval, nausea, vomiting, appetite changes, weight loss, and bloody or black stools.

    Blood Test

    • A blood test is used to diagnose peptic ulcer. The test checks for bacteria called H. pylori antibodies which are associated with peptic ulcer formation.

    Breath Test

    • A breath test can be used to test for H. pylori antibodies. The patient drinks a beverage containing radioactive carbon then breathes into a bag to reveal bacterial contamination.

    Stool Test

    • Peptic ulcers can be diagnosed with a stool antigen test which checks for bacteria and can be used to monitor success of treatment.

    Diagnostic Tests

    • An upper gastrointestinal x-ray can detect some peptic ulcers. A physician may perform an endoscopy during which a tube with a camera on the end is sent down the throat and esophagus. This will show any peptic ulcers present in the upper digestive tract.
