Overview

Gastritis: Please check these three things first

  • Gastritis refers to inflammation of the stomach lining; endoscopic findings and the discomfort you currently feel must be viewed separately.
  • In some cases, treatment tailored to the cause, such as Helicobacter infection or the use of NSAIDs (painkillers/anti-inflammatories), is required first.
  • If feelings of fullness or epigastric pain persist after treatment, Functional Dyspepsiawe check if these occur together.

Definitions and Distinctions

What is gastritis?

Helicobacter pylori Causes vary, including infection, NSAIDs, and autoimmune conditions. The severity of gastritis findings does not always correlate with the intensity of indigestion. Gastritis is a state where inflammation occurs in the inner lining of the stomach. The diagnosis confirmed via endoscopy or biopsy and the heartburn or epigastric discomfort felt by the patient may overlap or appear separately.

Easily Confused Terms
Functional dyspepsia is a condition where post-meal fullnessearly satietyor epigastric pain recurs, even if there are no structural changes in tests that sufficiently explain the symptoms. Both diagnoses can coexist.
Why this is checked during the medical evaluation
To establish treatment goals, we must look beyond just the endoscopy results and consider current remaining symptoms, whether Helicobacter testing and treatment were performed, medications being taken, and changes after meals.
Information to prepare
Please bring your test date, result sheet, and information on whether you received Helicobacter treatment. If you experience vomiting blood, black and sticky stools, dizziness, or continuous weight loss, seek prompt medical evaluation.

Connecting gastritis to your symptoms

Endoscopic findings of gastritis do not necessarily correlate with current discomfort

You may have gastritis findings with almost no symptoms, or you may have mild findings but experience significant post-meal fullness and epigastric pain. Rather than ignoring the test results, we set treatment goals by considering Helicobacter status, medications, and remaining symptoms together.

We check for ulcers and bleeding first, then address remaining indigestion

We verify if you are taking NSAIDs or if you have completed Helicobacter treatment. If you have vomiting blood, black and sticky stools, dizziness, or weight loss, a prompt medical evaluation is the priority. After treating the cause, stuffy feelingif epigastric pain and early satiety remain, we check for coexisting functional dyspepsia.

Check the location and cause of gastritis on your endoscopy report

Rather than just remembering that 'there is gastritis,' please bring the specific findings written (such as erosive or atrophic gastritis), biopsy results, and Helicobacter results. Also, note your use of NSAIDs, alcohol consumption, and symptoms remaining after treatment. After confirming the risk of bleeding and ulcers, we check if post-meal fullness and epigastric pain overlap with functional dyspepsia.

Frequently Asked Questions

Frequently asked questions about gastritis

If endoscopy shows chronic gastritis, do I have to take medication indefinitely?

It depends on the type and cause of the endoscopic findings and your current symptoms. We check for Helicobacter infection or the influence of medications, and any bloating that persists regardless of the findings is addressed as a separate treatment goal.

I have gastritis; when should I consider herbal medicine treatment?

While continuing treatment for bleeding, ulcers, or infections, if postprandial fullness, epigastric pain, or nausea recur, we review the test results and current medications to set the primary goal of herbal medicine treatment among gastrointestinal motility, sensitivity, or dietary recovery.
