Not all atrophic gastritis can be cured, but it can be treated and relieved by medication such as aluminum thioglycollate and mosapride, surgery and endoscopic treatment. 1. Drug treatment: such as gastric mucosa protection drugs and gastrointestinal power drugs. (1) Gastric mucosal protective drugs: such as aluminum sulfate, which can neutralize gastric acid and cover the surface of gastric mucosa to protect gastric mucosa. Renal insufficiency is prohibited. Adverse reactions include constipation, lethargy, dry mouth and so on. (2) Gastrointestinal dynamics drugs: with the development of atrophic gastritis, there will be a lack of gastric acid or a decline in gastric acid secretion, which will further increase the damage to the patient’s digestive function and lead to indigestion. Mosapride is commonly used and is contraindicated in patients with intestinal obstruction, gastrointestinal bleeding, and electrolyte disorders. Adverse reactions such as diarrhea, abdominal pain and skin rash may occur after taking the drug. 2. Surgical treatment: when drug treatment is ineffective, atrophic gastritis is easy to become cancerous in some patients. If there are symptoms such as atrophy, intestinalization, atypical hyperplasia, etc., patients should carry out pathological examination and closely monitor their vital signs, and once there is cancerous phenomenon, they should be treated with surgery in time, such as gastric colectomy. 3. Endoscopic treatment: endoscopic minimally invasive techniques are often used for treatment, such as argon ion coagulation and endoscopic resection. Patients with atrophic gastritis should go to the hospital in time, follow the doctor’s instructions and actively treat to prevent the gastric mucosa lesions continue to develop.
