What are Gastritis and Gastropathy?

Gastritis and gastropathy are conditions that affect the stomach lining, also known as the mucosa. In gastritis, the stomach lining is inflamed. In gastropathy, the stomach lining is damaged, but little or no inflammation is present.​

Are there different types of Gastritis and Gastropathy?

Experts have identified many types of gastritis and gastropathy, which have different causes.​
Gastritis and gastropathy may be chronic, developing slowly and lasting a long time, or acute, developing suddenly and lasting a short time. Some forms are erosive, meaning that they wear away the stomach lining and cause shallow breaks, called erosions, and ulcers. Other forms are non-erosive.



Helicobacter pylori (H. pylori) gastritis is one of the most common types of gastritis. Caused by infection with H. pylori bacteria, this type of gastritis is chronic and one of the most important causes of peptic ulcer disease.

Without treatment for the bacterial infection, H. pylori gastritis can last a lifetime and increase the chance of developing stomach cancer.


Reactive gastropathy develops when the stomach lining comes into contact with irritating substances over a long period of time.
Some types of pain relief medicines called nonsteroidal anti-inflammatory drugs (NSAIDs), alcohol, and bile are among the most common irritating substances.
Reactive gastropathy is chronic and can be erosive. NSAIDs are the most common noninfectious cause of peptic ulcers and can cause life-threatening bleeding, obstruction, or perforation of the stomach or small intestine.​


Autoimmune gastritis occurs when the immune system attacks healthy cells in the stomach lining. Autoimmune gastritis is chronic and typically nonerosive.​


Acute erosive gastropathy may occur after contact with irritating substances, such as NSAIDS, alcohol, or cocaine. A form of acute erosive gastropathy called stress gastritis develops when serious health problems — such as severe injuries or burns, critical illness, or sepsis — reduce the blood flow to the stomach lining.
This reduced blood flow prevents the stomach’s protective mechanisms from working normally, which allows stomach acid to come into contact with and damage the stomach lining.​
In acute erosive gastropathy, the stomach lining quickly develops erosions, ulcers, and bleeding. The bleeding is most often mild but may be severe.​
