Drinking beer often is harmful to the body, not only will the chances of suffering from stomach diseases increase, some people will also induce alcoholic liver and gout attacks. Beer contains a large amount of ethanol, which, when it enters the stomach, dissolves the mucus secreted by the gastric mucosa. This damages the protective barrier of the stomach and therefore makes it more susceptible to the stimulation of stomach acid and alcohol. Regular beer drinking can lead to long-term damage to the gastric mucosa, so the likelihood of these people suffering from gastritis, gastric ulcers, and duodenal ulcers increases. After entering the stomach, beer is rapidly absorbed and enters the body’s blood circulation. Alcohol is metabolized mainly by the liver, so drinking beer for a long time can lead to an increased burden on the liver and even trigger an attack of alcoholic liver. When beer enters the body, it will be metabolized into lactic acid, and when the body excretes lactic acid, the excretion of uric acid will be affected, and some people may even be triggered by gout attacks.
