Flatulence after drinking may be caused by alcohol damage to the gastric mucosa, causing indigestion, or it may be caused by gastrointestinal dysfunction, gastritis, gastric ulcers and so on. It can be treated by drinking warm water, taking omeprazole, thioglycollate and other drugs. 1. General treatment: It is recommended to drink more warm water to dilute the alcohol concentration, promote alcohol metabolism, and reduce the damage of alcohol on the gastric mucosa, and at the same time, attention should be paid to warmth, and consume easy-to-digest foods such as milk and rice porridge. 2. Medication: If the patient’s symptoms are obvious, drugs that inhibit the secretion of gastric acid and protect the gastric mucosa can be used, such as rabeprazole, omeprazole and aluminum sulfate. The above drugs are prohibited for those who are allergic to them and should be taken in accordance with medical advice. If the patient’s symptoms of abdominal distension are serious, or persist without improvement, it is recommended to go to the regular hospital in time, after clarifying the cause of the disease, under the guidance of the doctor to carry out targeted treatment.
