1) Eat regularly and eat less cold food and snacks. 2) Take some stomach health care drugs and drugs that increase gastric motility, such as Yangwei Granules (improving gastric motility) and Jianwei Xiaoshi Tablets (promoting digestion). The commonly used gastric motility drugs in clinic include metoclopramide, motilium and cisapride. It is mainly used to treat gastric distension, nausea, vomiting, fever and other symptoms caused by decreased gastric motility, delayed gastric emptying and esophageal reflux. (1) metoclopramide: Also known as metoclopramide, metoclopramide has an exciting effect on gastrointestinal tract, which can strengthen gastric antrum peristalsis and relax pyloric sphincter. Promote the emptying of food in the stomach, so that it can be used to treat fever, loss of appetite, bloating, gastroptosis and other symptoms. In addition, it is also used to treat cholecystitis and gallstones, because it can relax the sphincter of bile duct and regulate bile duct movement and bile secretion. However, when the drug is used repeatedly or the dose is too large, there will be extrapyramidal reactions, such as muscle tremor, convulsions and other adverse reactions. (2) Domperidone, also known as Domperidone, is a peripheral dopamine receptor blocker, which can enhance gastric peristalsis, promote gastric emptying, inhibit nausea and vomiting, and effectively prevent bile reflux. It is not easy to cross the blood-brain barrier. So there are few side effects of central nervous system and extrapyramidal system, so it is more widely used than metoclopramide. Because there is no injection at present, patients who can't take it orally should choose metoclopramide injection for treatment. (3) Cisapride, also known as Prebos, is a new generation of gastrointestinal motility drugs. Acting on the myenteric plexus, it can release acetylcholine physiologically, directly promote gastrointestinal movement, and does not block dopamine receptors and directly stimulate cholinergic receptors, so the side effects are small. It can be used for treating gastroparesis, gastroesophageal reflux, insufficient propulsive peristalsis caused by pseudo intestinal obstruction, stagnation of gastrointestinal contents, chronic constipation, etc.
