Chronic gastric sinusitis is usually cured, but its treatment is related to the classification of the disease. It is mainly divided into chronic gastric sinusitis with erosion, chronic gastric sinusitis with bile reflux, chronic gastric sinusitis caused by Helicobacter pylori, chronic gastric sinusitis caused by non-steroidal anti-inflammatory drugs, and simple gastric sinus with lamellar erythema. 1. Chronic gastric sinusitis with erosion: mainly through the inhibition of gastric acid treatment, gastric acid secretion will be reduced after the erosion will repair itself. 2. Chronic gastric sinusitis with bile reflux: need to use drugs such as domperidone, trimethoprim maleate, mosapride citrate and other drugs to regulate gastric dynamics, and use magnesium aluminum carbonate tablets to adsorb bile to reduce bile reflux. 3. Chronic sinusitis caused by Helicobacter pylori: the first step is to eradicate Helicobacter pylori, which will be cured soon after standardized treatment. 4. Chronic sinusitis caused by non-steroidal anti-inflammatory drugs: stop using the drugs. 5. Simple gastric sinus with flaky erythema: without other symptoms such as erosion and bile reflux, it can be observed and followed up. Chronic gastric sinusitis is a common disease, most can be cured, the specific treatment needs to be examined in the hospital by a professional doctor’s judgment. Drugs need to be used under the guidance of a doctor.
