Alcohol stimulates the stomach lining, causing it to secrete more digestive acid. As both alcohol and acid build up in your stomach, you may experience nausea and vomiting.|When alcohol enters the body it is quickly absorbed with 20% absorbed in the stomach and 80% in the small intestine, after 30-60 minutes all alcohol is absorbed. After that, alcohol is metabolized mainly in the liver (90%). During this process, the liver is subjected to an attack of many toxins.|At that time, the function of preventing various toxins carried by the blood from the intestines or outside to the liver is impaired, leading to fatty liver, cirrhosis, and more seriously, it can cause liver cancer.|Normally, the pancreas is the site of insulin production, which helps regulate blood sugar levels and a host of other hormones that help the intestines digest food.|When you drink a lot of alcohol, the production of these hormones is disrupted or slowed down. Along with that, toxins that accumulate into the pancreas can cause pancreatitis, which gradually leads to more serious damage.
