After drinking a lot of alcohol, alcohol enters the gastrointestinal tract to the duodenum, stimulating the pancreatic cells to secrete digestive enzymes on a large scale, causing the pancreatic ducts to become unobstructed and blocked, at which time large quantities of digestive enzymes gather in the pancreatic ducts and pancreatic cells, causing the pancreatic glandular vesicles to rupture. Therefore, when drinking alcohol, you must pay attention to not drink or drink as little as possible, and eat a small amount of carbohydrates before drinking or take gastric mucosa-protective drugs, which can reduce alcohol absorption, play a protective role and reduce the onset of pancreatitis.
