Generally speaking, gastric distension may be caused by acute and chronic gastritis, peptic ulcer, gastric cancer, functional dyspepsia, etc. At present, oral medication rather than infusion is often used in clinical treatment, such as oral magnesium aluminum carbonate, domperidone, omeprazole, etc. 1. Gastric mucosal protectants: such as aluminum sulfate, bismuth potassium citrate, bismuth pectin, teprenone, etc., which can form a layer of protective coating on the gastric mucosa, protect the gastric mucosa from gastric acid, food and other stimuli, improve gastric mucosal blood flow, thus relieving symptoms such as bloating. 2. Drugs that inhibit gastric acid secretion: such as ranitidine, famotidine, rabeprazole, lansoprazole, omeprazole, epprazole, etc., can inhibit the secretion of gastric acid, so as to alleviate the further corrosion and damage of the gastric mucous membrane by gastric acid, and improve the symptoms of gastric pain, acid reflux, nausea, gastric distension and so on. 3. Gastric stimulants: such as domperidone, mosapride, cisapride, itopride, etc., can promote gastrointestinal peristalsis and improve symptoms of indigestion such as bloating, early satiety, nausea and loss of appetite. Stomach bloating is recommended to consult a doctor in time to clarify the diagnosis and carry out targeted treatment. It should be noted that all of the above drugs should be used under the guidance of a doctor, not unauthorized use of drugs.
