The patient has hyperacidity, which is directly related to the high secretion of stomach acid or after eating irritating food, which causes high secretion of stomach acid. It can be neutralized first by drugs that neutralize stomach acid, such as sodium bicarbonate, aluminum hydroxide and other drugs. To treat the cause of stomach acid, if there is excessive stomach acid after eating irritating food, it is necessary to avoid eating such food, and at the same time, it is necessary to use drugs to inhibit stomach acid, such as using omeprazole, lansoprazole and other drugs to treat. In addition, if there is Helicobacter pylori infection in the stomach, it can also cause excessive stomach acid, and this bacterium needs to be killed with quadruple therapy. Omeprazole plus amoxicillin, clarithromycin and colloidal bismuth pectin are commonly used to kill it. Only after the bacterium is eliminated will the symptoms of hyperacidity be cured.
