Your doctor will likely review your signs and symptoms and perform a physical examination. A number of diagnostic tests may help your doctor determine the cause of your discomfort. These may include:

  • Blood tests. Blood tests may help rule out other diseases that can cause signs and symptoms similar to those of nonulcer stomach pain.
  • Tests for a bacterium. Your doctor may recommend a test to look for a bacterium called Helicobacter pylori (H. pylori) that can cause stomach problems. H. pylori testing may use your blood, stool or breath.
  • Using a scope to examine your digestive system. A thin, flexible, lighted instrument (endoscope) is passed down your throat so that your doctor can view your esophagus, stomach and the first part of your small intestine (duodenum).
