Peptic Ulcer Diagnosis: Symptoms, Causes & Testing

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.

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.
