Clinically there is no such thing as the three major hazards of alcohol consumption, but long-term, heavy drinking is detrimental to the health of the organism and should be taken seriously. The general population can drink alcohol in moderation, but there is no special benefit or effect. If people drink a large amount of alcohol over a long period of time, it may affect their health, increase the burden on the liver, kidneys, heart and other organs, and even increase the risk of alcoholic hepatitis, fatty liver, cirrhosis of the liver, nephritis, coronary heart disease, myocardial infarction, etc., which should be taken seriously. Some people may also suffer from gastritis, gastric ulcer, esophagitis, gastroenteritis, gastric cancer, esophageal cancer, intestinal cancer and other diseases due to the long-term stimulation of the digestive tract by alcohol, which increases the risk of gastritis, gastric ulcer, esophagitis, gastroenteritis and other diseases. In addition to the above hazards, alcohol has a greater impact on the nervous system, easily increasing the risk of cerebral hemorrhage, cerebral infarction and other diseases. It is recommended to drink alcohol in moderation and avoid prolonged and heavy drinking in order to minimize the damage caused by alcohol to the body. If you feel unwell after drinking alcohol, you should consult a doctor in time.
