Diagnosing Gastritis

Overview

Gastritis is a condition that occurs when the lining of the stomach (stomach wall) becomes inflamed. To diagnose gastritis, healthcare providers may perform several examinations, screening tests, and procedures. These include:

Physical examination: During a physical exam, a doctor will assess your symptoms and check for signs of gastritis, such as tenderness in the abdomen.
Medical history: Your doctor will ask about your medical history and any risk factors that may contribute to gastritis, such as alcohol consumption or medication use.
Endoscopy: This outpatient procedure involves a healthcare provider using a flexible tube with a camera to examine the lining of your stomach and duodenum. They may also take small tissue samples (biopsy) for further analysis during the endoscopy.
Blood tests: Blood tests can help identify markers of inflammation and possible underlying causes of gastritis, such as autoimmune disorders. These tests can also check for the presence of Helicobacter pylori bacteria or evaluate kidney and liver function.
Stool tests: Stool samples may be collected to check for traces of blood or Helicobacter pylori bacteria.
Breath test: A breath test can detect Helicobacter pylori by analyzing breath samples after ingesting a special solution.
Upper gastrointestinal series or barium swallow: In some cases, X-rays of the esophagus, stomach, and small intestine may be performed to diagnose gastritis.
Esophageal pH monitoring: This test is used to investigate whether a person has gastroesophageal reflux disease (GERD). Catheters or capsules are used to measure stomach acid levels over time.

These examinations and tests are performed by various specialists involved in diagnosing gastritis:

Gastroenterologist: A specialist in digestive disorders who typically performs endoscopies and interprets results.
Primary care physician (PCP): The first point of contact who may perform initial assessments and refer patients to specialists if needed.
Pathologist: Analyzes tissue samples taken during endoscopy to determine if there are any abnormalities.
Radiologist: Interprets X-ray images if an upper gastrointestinal series is performed.

It's important to note that while these tests can help diagnose gastritis and provide valuable information about its type, severity, or stage, it's always recommended to consult with a healthcare professional for an accurate diagnosis and personalized treatment plan.
