Alcohol is harmful to human body, which may cause damage to many organs such as brain, liver, pancreas, heart and stomach, and may also cause malnutrition and alcoholism. The main way to obtain alcohol is drinking, so it is recommended to drink as little as possible in life, and avoid contact with alcoholic products as much as possible unless it is necessary to ensure good health.

First, damaged organs:

1, brain: Alcohol can stimulate the nerves of the brain, which easily leads to excitement, restlessness, irritability and other mental states in a short period of time, which will have an impact on normal life and others. Long-term intake of alcohol can easily lead to alcoholic encephalopathy, and hand tremor caused by chronic alcoholism can also lead to a decline in the ability to take things, which can endanger life safety in severe cases;

2. Liver: The liver is the largest metabolic organ of the human body and bears the metabolism of alcohol. For example, long-term drinking will easily lead to the aggravation of the metabolic burden of the liver and the formation of fatty liver, and it will also easily lead to alcoholic hepatitis under the stimulation of alcohol. If not treated and controlled in time, it will easily lead to cirrhosis and liver cancer;

3. Pancreas: The pancreas is also one of the metabolic organs of alcohol. Alcohol can cause damage to pancreatic cells. A large amount of drinking may induce acute pancreatitis. Long-term drinking is prone to pancreatic fibrosis, which in turn leads to pancreatitis and even pancreatic cancer;

4. Heart: Alcohol can accelerate the contraction and expansion of blood vessels, and the brain and heart are particularly important blood supply parts. In the case of drinking a lot, it is easy to induce palpitations, chest tightness, shortness of breath and so on. Long-term drinkers can induce coronary heart disease, myocardial infarction, cerebral hemorrhage and other diseases;

5, stomach: alcohol will stimulate the gastric mucosa, patients are more prone to stomach pain, stomach cramps, diarrhea, vomiting, indigestion and other symptoms, but also prone to gastritis, gastric ulcer, gastric bleeding, gastric mucosal erosion and other diseases.
