Gastritis is classified according to various criteria.
The most important distinction is based on clinical progression. There are two main types:
-
Acute gastritis
-
Chronic gastritis
Acute gastritis develops rapidly and is accompanied by pronounced symptoms. It usually occurs due to aggressive effects on the stomach lining by certain foods, drinks, medications, etc.
Chronic gastritis develops following acute gastritis. It is characterized by alternating periods of exacerbation and remission. The symptoms are less pronounced.
Depending on the level of acidity, gastritis is divided into normal-acid, high-acid, and low-acid gastritis.
By the type of mucosal lesion, the following are distinguished:
- superficial gastritis — an initial lesion in which inflammation affects only the upper layers of the mucous membrane without deep structural changes;
- erosive gastritis — is characterized by the formation of superficial defects (erosions) that can cause pain and discomfort;
- atrophic gastritis — is accompanied by gradual thinning of the mucous membrane and a decrease in its function;
- hypertrophic gastritis — is associated with thickening of the mucous membrane and changes in its structure;
This classification makes it possible to assess more accurately the nature of changes in the gastric mucosa and to choose the appropriate treatment tactics.
