How do I know if I have Gastritis?

Gastritis is characterized by the inflammation, irritation, or erosion of the stomach lining, often presenting as gnawing abdominal pain, nausea, or a sense of fullness in the upper abdomen. To determine if you have gastritis, you should track your symptoms and consult a gastroenterologist for diagnostic testing, such as an endoscopy or breath test, to identify the underlying cause like H. pylori infection or chronic NSAID use.

What are the early signs and symptoms of gastritis?

Gastritis symptoms can vary significantly between individuals; our 78 community members at DiseaseMaps.org report experiences ranging from mild discomfort to debilitating pain. The most common indicators of gastritis include a burning or gnawing ache in your upper abdomen that may either worsen or improve when you eat. Other early signs include frequent nausea, vomiting, a feeling of persistent fullness in your upper abdomen after eating, and unintended weight loss. It is important to distinguish gastritis from simple indigestion; while indigestion is often transient and food-related, the discomfort of gastritis tends to be more persistent and localized to the epigastric region.

When should you consult a doctor about your symptoms?

You should schedule an appointment with a primary care physician or gastroenterologist if your stomach symptoms persist for more than a week. When you speak to your doctor, be prepared to describe the frequency, duration, and intensity of your pain, as well as any triggers you have noticed. To help your clinician diagnose gastritis, consider keeping a symptom log for 7-10 days. Be specific about your use of over-the-counter medications like aspirin, ibuprofen, or naproxen, as long-term use of these non-steroidal anti-inflammatory drugs (NSAIDs) is a leading cause of gastritis.

Which diagnostic tests are used for gastritis?

If your physician suspects gastritis, they will likely order specific tests to confirm the diagnosis and identify the underlying trigger. Common diagnostic steps include:

• H. pylori testing: A breath test, stool test, or blood test to detect this common bacterium.


• Upper endoscopy: A procedure where a thin, flexible tube with a camera is passed down your throat to inspect your stomach lining.


• Biopsy: During an endoscopy, a small tissue sample may be taken to check for inflammation or infection.


• Blood tests: To check for anemia, which can be a sign of chronic blood loss from a stomach lining erosion.

What are the red flags requiring urgent medical evaluation?

While many cases of gastritis are manageable, certain symptoms indicate a potential complication, such as bleeding or a perforation, and require immediate emergency care. Seek urgent medical attention if you experience:

• Vomiting blood or material that looks like coffee grounds.


• Stools that are black, tarry, or contain visible bright red blood.


• Severe, sharp, or sudden abdominal pain that does not subside.


• Unexplained dizziness, fainting, or shortness of breath.

How do you advocate for your health?

If you feel your concerns regarding potential gastritis are being dismissed, it is vital to advocate for yourself by requesting a clear explanation of why certain tests are being declined. You have the right to request a referral to a gastroenterologist, a specialist who focuses specifically on the digestive tract. Bring your symptom log to the appointment and ask, "What specific diagnostic steps can we take to rule out gastritis or other underlying inflammatory conditions?"
