Nausea and vomiting after drinking is mainly related to the stimulation of the gastrointestinal mucosa by alcohol, which can be relieved by increasing water intake, adjusting diet and medication. 1. Increase drinking water: Drinking some warm water can dilute the concentration of alcohol and reduce the stimulation of the gastrointestinal mucosa, thus improving the symptoms of vomiting. In addition, timely hydration can also avoid the symptoms of dehydration caused by water loss due to vomiting. 2. Adjust the diet: moderate consumption of some alkaline fluids, such as milk, rice porridge, etc., can dilute the alcohol concentration, neutralize gastric acid, protect the gastric mucosa, but also can play a role in relieving vomiting. 3. Medication: If the vomiting is serious, you can take metoclopramide, omeprazole and other drugs for treatment. The above drugs are prohibited for those who are allergic to them, and they should be taken in accordance with medical advice. If the patient has nausea and vomiting after drinking, it is recommended to go to the regular hospital in time, after clarifying the cause of the disease, under the guidance of the doctor for targeted treatment.
