Generally speaking, if you take too many stomach medicines, you will not lose weight. Common gastric drugs include acid-suppressing drugs, gastric mucosa-protecting drugs, gastrointestinal dynamics drugs and so on. 1. Acid-suppressing drugs: they can be divided into Hâ‚‚ receptor blockers such as ranitidine and cimetidine, and proton pump inhibitors such as lansoprazole, esomeprazole, omeprazole, rabeprazole, etc., which can inhibit the secretion of gastric acid effectively, thus alleviating the symptoms of acid reflux and stomach pain. 2. Gastric mucosal protection drugs: such as aluminum sulfate, bismuth pectin, teprenone, gefalate, etc., through the formation of a layer of protective film on the surface of the gastric mucosa, thus preventing food, gastric acid and other damage to the gastric mucosa and erosion. 3. Gastrointestinal dynamics drugs: such as Cisapride, Itopride, Domperidone, etc., can promote gastrointestinal motility to improve the symptoms of indigestion such as bloating, loss of appetite, nausea and so on. The main role of gastric drugs is to improve stomach pain, bloating, acid reflux, heartburn, nausea, vomiting, loss of appetite and other symptoms, and can not play a role in weight loss. It should be noted that all of the above medications should be taken under the guidance of a doctor, and should not be used without authorization.
