The treatment of gastric sinus atrophic gastritis with enteroepithelialization mainly includes improvement of living and dietary habits, drug therapy, and regular review. 1. Improvement of living and dietary habits: patients with focal intestinal epithelial growth are recommended to eat fewer meals and pay attention to dietary diversity; eat less nitrite-rich and nitrate-rich food as much as possible; do not eat moldy food; avoid too spicy and rough food; avoid long-term alcoholism and smoking; maintain a good psychological state and get enough sleep. 2. Medication: Helicobacter pylori is the main cause of gastric sinus atrophic gastritis with enteritis. Patients can use quadruple therapy to eradicate H. pylori, i.e. 1 proton pump inhibitor (such as omeprazole) + 1 bismuth agent (such as bismuth potassium citrate) + 2 antibiotics (such as amoxicillin, metronidazole). Antacid drugs, anti-anxiety and antidepressant drugs can also be applied appropriately according to the patient’s symptoms. 3. Regular review: It is recommended that patients with gastric sinus atrophic gastritis with intestinalization should have a review of e-gastroscopy once every six months to avoid further development of the disease. The above drugs should be used under the guidance of a professional physician. If you have gastric sinus atrophic gastritis with enterocolitis, you should go to the gastroenterology department in time, under the guidance of a professional physician for treatment, and review on time to avoid disease progression.
