What are the causes and treatments for atrophic gastritis?

Atrophic gastritis is mainly related to factors such as infection, taking nonsteroidal anti-inflammatory drugs, and bile reflux.

Atrophic gastritis is mostly caused by Helicobacter pylori infection and can be treated with oral antibiotics under the guidance of a doctor, such as metronidazole tablets, amoxicillin capsules, clarithromycin tablets, etc.

Long-term use of NSAIDs can lead to gastric mucosal congestion and eventually atrophic gastritis. You should stop taking NSAIDs.

Pyloric sphincter dysfunction can lead to a large amount of bile reflux, damage the gastric mucosa, and cause atrophic gastritis. You can follow the doctor's instructions for oral treatment with drugs that inhibit gastric acid secretion, such as ranitidine hydrochloride tablets, cimetidine tablets, nizatidine tablets, etc.
