Diagnosing Atrophic Gastritis

Overview

To diagnose atrophic gastritis, several examinations, screening tests, and procedures may be done. These tests help confirm the diagnosis and determine the type, severity, or stage of the condition. Here's what you need to know:

Medical history and physical exam: Your healthcare provider will ask about your symptoms and medical history. During the physical exam, they will look for signs of a medical problem such as pain or tenderness in your abdomen.
Laboratory (lab) tests: Blood tests can be ordered to check for markers of inflammation and possible underlying causes, such as autoimmune disorders. Stool samples may also be collected to check for traces of blood or the presence of Helicobacter pylori bacteria.
Endoscopy: This outpatient procedure involves a healthcare professional using a flexible tube with a camera to examine the lining of your stomach and duodenum. During an endoscopy, small tissue samples (biopsies) may be taken for further analysis. Examination of tissue biopsies under a microscope can identify changes associated with atrophic gastritis. In some cases, specialized types of endoscopies may be used to assess the severity of atrophic gastritis.
Imaging studies: Your doctor may recommend imaging studies like X-rays or magnetic resonance imaging (MRI) scans to get a closer look at your stomach and surrounding organs.

These examinations and tests help confirm the diagnosis of atrophic gastritis by identifying signs of inflammation in the stomach lining and ruling out other possible causes of your symptoms.

Specialists involved in diagnosing atrophic gastritis may include:

Gastroenterologists: These doctors specialize in diagnosing and treating conditions related to the digestive system, including atrophic gastritis.
Primary care physicians (PCPs): PCPs may initially evaluate your symptoms and refer you to specialists if necessary.
Nurses, physician's assistants, and lab technicians: These healthcare professionals may perform clinical procedures and assist in collecting samples for testing before results are reviewed by your doctor.

Remember that it's important to consult with a doctor regarding any concerns or symptoms you may have related to atrophic gastritis. They can provide personalized advice based on your specific situation.
