Long-term excessive alcohol consumption can cause damage to the stomach or liver, where the damage to the stomach is manifested as gastric erosion and gastritis in mild cases; in more severe cases, it can cause peptic ulcers, and in especially severe cases, it can cause peptic ulcers with perforation or bleeding, which need to be clarified by electronic gastroscopy, and when electronic gastroscopy reveals damage to the gastric mucosa above gastric erosion, it is recommended to stop drinking as soon as possible. For liver damage, mainly manifested as elevated transaminases, fatty liver, alcoholic hepatitis and alcoholic cirrhosis, blood tests, liver ultrasound and liver function tests are needed to clarify. When serious elevation of transaminases in the liver is found, it is necessary to stop drinking as soon as possible. When cirrhosis is present, liver transplantation or liver protection therapy is required.
