What’s the best way to relieve a stomach ache the day after drinking?

Stomach pain the next day after drinking alcohol is considered gastric mucosal damage, which can be relieved by dietary modification and oral administration of gastric mucosal protective agents such as aluminum sulfate and acid inhibitors such as omeprazole.
Drinking alcohol can cause damage to the gastric mucosa, secrete a large amount of gastric acid, causing acute congestion, edema, or even erosion of the gastric mucosa.
If the symptoms of stomach pain are not serious, you can give warm water, rice porridge, hot milk and other liquid diet, which can play a role in diluting gastric acid, protect the gastric mucosa, and then relieve the symptoms of stomach pain.
If the symptoms are more serious, gastric mucosa protector and acid suppressant can be given for treatment.
Commonly used gastric mucosal protectants include bismuth pectin and aluminum thioglycollate, etc. Commonly used proton pump acid inhibitors include omeprazole and lansoprazole. If the symptoms of stomach pain are accompanied by reflux in addition to gastric pain symptoms, it is necessary to give drugs to promote gastric power, such as mosapride, domperidone tablets and so on. Drugs should be used under the guidance of a doctor.
In daily life, quit smoking and drinking, and do not drink strong tea and coffee and other foods that tend to irritate the gastric mucosa. Give light, warm, soft and easy-to-digest food, avoid spicy and stimulating food, and eat less and more frequent meals to promote the repair of gastric mucosa.
