Stomach discomfort and nausea can be treated with drugs such as domperidone, omeprazole, bismuth in pectin, stomachic tablets and lactase. Some people experience stomach discomfort and nausea because of insufficient gastrointestinal power, which leads to food treatment. These people can use domperidone in their choice of medication. This medication can promote the restoration of gastrointestinal power and shorten the time food stays in the stomach, and also enhance the tension of the esophageal sphincter, so it can relieve nausea and vomiting. When stomach discomfort and nausea are accompanied by severe stomach pain, most of them are caused by gastric ulcer disease and should be treated with drugs that inhibit stomach acid and promote mucosal repair, such as omeprazole and pectin bismuth. Some people experience stomach discomfort after a large intake of food, which is related to indigestion, and can be treated with stomach-healthy tablets, which can not only improve the function of the spleen and stomach, but also promote the digestion of food in the stomach, thus relieving stomach discomfort and nausea symptoms. Lactase is a digestive aid, which is rich in digestive enzymes that can help the breakdown of food in the stomach, while promoting the digestion and emptying of food, reducing nausea and vomiting.
