"The first choice for treating stomach diseases is to use acid inhibitors in combination with gastric mucosal protective agents. Commonly used acid inhibitors are proton pump inhibitors ppi, including omeprazole, lansoprazole, pantoprazole, rabeprazole and esomeprazole. Commonly used gastric mucosal protectants are bismuth, including bismuth potassium citrate, colloidal pectin bismuth, bismuth magnesium in the stomach and so on. It is necessary to give corresponding treatment according to specific diseases. The total course of treatment for chronic gastritis and peptic ulcer is 4-8 weeks. If there is Helicobacter pylori infection in the stomach, it is recommended to give Helicobacter pylori eradication treatment as appropriate. The recommended therapy is quadruple therapy, ppi plus bismuth plus two antibiotics. The course of HP eradication is 10- 14 days. In addition, we must pay attention to changing lifestyles and eating habits to avoid fatigue, overeating, and taking non-steroidal anti-inflammatory drugs. "
