Physiological factors: improper diet, mental stress and other conditions may cause increased secretion of gastric acid, causing physiological acid reflux. It can be relieved by adjusting the diet and maintaining a good mood, and usually does not require medication. 2. Gastroesophageal Reflux Disease (GERD): Elevate the head of the bed when sleeping, do not eat before going to bed, avoid eating coffee, strong tea, chocolate and other foods that will cause the lower esophageal sphincter to relax, and also use gastric motivation medication such as domperidone and moxapride, as well as acid inhibiting medication such as omeprazole, etc. to reduce the stimulation of gastric acid. 3. Peptic ulcer: Lansoprazole, pantoprazole and other acid-suppressing drugs can be used to treat, but also use aluminum thioglycollate and other gastric mucous membrane protective agent treatment, daily life should maintain a regular diet, eat small meals, avoid overeating.
