Chronic atrophic gastritis may be caused by poor dietary habits, autoimmune factors, Helicobacter pylori infection, bile reflux and other reasons.
1. Bad dietary habits: due to irregular diet, often overeating, heavy drinking or eating too much spicy and irritating food, may cause chronic damage to the gastric mucosa, which leads to the occurrence of chronic atrophic gastritis.
2. Autoimmune factors: If the autoimmune low, such as the elderly, the gastric mucosa degenerative changes, mucosal repair ability is weak, and ultimately lead to chronic changes in the inflammation of the stomach, chronic atrophic gastritis.
3. Helicobacter pylori infection: Due to autoimmune abnormalities, the intestinal mucosal epithelium may be infected by Helicobacter pylori, resulting in recurrent inflammation of the intestinal mucosal epithelium, thus triggering chronic atrophic gastritis.
4. Bile reflux: Due to the reflux of bile or duodenal fluid into the stomach, the gastric mucosal barrier is damaged, which may trigger inflammation and glandular atrophy.
There are other causes of chronic atrophic gastritis, you should go to the hospital in time to clarify the cause of the disease, and under the guidance of the doctor for targeted treatment.
