When you drink cold beer and have stomach pain, you can apply heat and massage to the abdomen, and some people need to use lansoprazole and aluminum thioglycollate for treatment. Cold beer will cause irritation to the gastric mucosa when drinking it because of its lower temperature, and many people will suffer from stomach pain due to spasmodic contraction of the stomach wall. For people who have relatively mild pain, they can be relieved by means of abdominal heat compresses and massage. Hot compresses and massage can not only promote the dissipation of the cold in the stomach, but also promote blood circulation in the stomach wall and release the smooth muscle spasm, so it can help improve the stomach pain. Some people who experience stomach pain when drinking cold beer are suffering from gastritis, gastric ulcer and other diseases, which need to be treated in order to get better. Lansoprazole is a drug that inhibits the secretion of gastric acid, which can prevent the gastric acid secretion from infringing on the gastric mucosa and facilitate the recovery of gastritis and gastric ulcer diseases. Aluminum thioglycollate is a mucosal protective agent that can isolate gastric acid from gastric mucosa, reduce the irritation of gastric acid, and also touch the repair of mucosal cells of gastric wall.
