Chronic gastritis

By Medically reviewed by hellodoktor


What is chronic gastritis?

Chronic gastritis is a condition occurs when your stomach lining becomes inflamed. The signs and symptoms of this disease can be painless or cause dull, persistent stomach pain.

The most common type of chronic gastritis is caused by Helicobacter pylori bacteria. Chronic gastritis usually gets better with treatment, but may require ongoing monitoring.

Bacteria, consuming too much alcohol, certain medications, chronic stress, or other immune system problems can lead to inflammation. When inflammation occurs, your stomach lining changes and loses some of its protective cells. It may also cause early satiety. This is where your stomach feels full after eating just a few bites of food.

Because chronic gastritis occurs over a long period of time it gradually wears away at your stomach lining. And it can cause metaplasia or dysplasia. These are precancerous changes in your cells that can lead to cancer if untreated.
