You need to continue taking medication for nausea, regurgitation, and vomiting, but you need to change the way you take the medication. Many medications can cause irritation to the mucous membrane of the digestive system and therefore cause digestive symptoms such as nausea, vomiting, and regurgitation after taking them. Although medications can cause side effects, these side effects are mild compared to the therapeutic effects of the medication and can be alleviated in a number of ways. Drugs that are irritating to the gastric mucosa should be taken after a meal, for example, about half an hour after a meal, as the food protects the drug from directly irritating the gastric mucosa, the resulting digestive reaction will be relatively mild and the ingredients of the drug will be digested and absorbed by the body. It is also necessary to drink more water after taking the drug to help dilute the ingredients of the drug and avoid damage to the gastric mucosa, as well as to promote the metabolism of the drug ingredients in the body and reduce the side effects caused by the drug. In case of vomiting, bloating and abdominal pain, it is best to go to the hospital for gastroscopy.
