Nausea and regurgitation after drinking are directly related to the direct stimulation of the gastric mucosa by alcohol, which interferes with the peristalsis and emptying of the stomach. If this situation occurs after drinking, you can drink a glass of milk or honey water after drinking, which has the effect of nourishing the stomach and can dilute the concentration of alcohol to avoid damage to the gastric mucosa. If the above practices do not work, you can use drugs such as Gastrofacial or VU Belladonna Aluminum Magnesium Tablets to stop the vomiting. If the patient has a previous history of gastritis, gastric erosion, peptic ulcer and other underlying diseases, drinking alcohol can cause aggravation of the above diseases. After drinking, pay special attention to diet and rest, and do not eat greasy food, but eat more light food.
