The course of treatment for non-atrophic gastritis is often 10 to 14 days. Gastritis is often associated with Helicobacter pylori infection, gastroduodenal reflux, drugs and toxins, and autoimmune conditions, and its clinical manifestations are mainly conditions such as discomfort in the upper and middle abdomen, fullness, dull ache, loss of appetite, acid reflux, and belching. The disease, if accompanied by Helicobacter pylori infection, is mainly treated with anti-Helicobacter pylori therapy (clarithromycin, amoxicillin, omeprazole, and bismuth), improvement of gastrointestinal dynamics (domperidone, etc.), and supplementation with multivitamins (vitamin B12, etc.). The course of treatment is often 10-14 days, and the prognosis of the disease is favorable. All of the above drugs should be administered under the supervision of a specialized doctor. If any of the above conditions occur, please consult a doctor in time for rational and standardized treatment.
