Chronic gastritis is a condition that emerges from the inflammation in the lining of the stomach. The inflammation of gastritis mostly occurs due to the infection with the same bacteria, which is linked to stomach ulcers. The excess consumption of pain relievers, stress, immune system disorders, and binge alcohol consumption can also relate to the risk of gastritis.

The stomach lining or mucosa has glands that generate acid in the stomach and other important substances, such as the enzyme pepsin. While the acid in your stomach breaks the food and protects you from infection, pepsin breaks down protein. The acid is so dangerous that it can also damage your stomach. To protect you from this damage, the stomach lining secretes mucus.

Gastritis occurs when there is inflammation in the lining of the stomach. Gastritis may occur promptly (acute) or slowly over time (chronic).

Chronic gastritis occurs when your stomach lining changes and breaks off its protective cells. It may also lead to early satisfaction, which makes you fuller after eating just a few bites of food.
