What are the main causes of chronic gastritis?

Chronic gastritis is mainly related to infection, immune abnormalities, bad eating habits and other factors.

1.

Helicobacter pylori infection is the most common cause of chronic gastritis, and its metabolic waste and toxins can lead to inflammatory damage to the gastric mucosa.

2. Immune abnormalities.

Inflammatory reactions caused by abnormal autoimmune function can lead to a decrease in the total number of parietal cells, atrophy of acid glands, and decreased gastric acid secretion, thus causing chronic gastritis.

3. Bad eating

habits.
