Excessive drinking has a great inhibitory effect on appetite, and many people who drink well eat less vegetables is the best example. Although wine is rich in nutrition, its content is not high after all, so it is unrealistic to regard drinking as a nutritional supplement. So drinking more and eating less can only lead to malnutrition.

2, vision loss

If the methanol contained in wine continues to decompose in human body, it will be converted into formaldehyde. This substance is very toxic to human retina. Long-term alcoholism will cause continuous damage to the retina, leading to rapid decline in vision and even blindness.

3. The liver injury is the most serious.

Alcohol contains alcohol, which has a direct toxic effect on human tissues and organs, and the most harmful part is the liver. When wine enters the human body, it first enters the stomach, about 20% is absorbed by the stomach, and about 80% is absorbed by the intestine. In any case, it can only be decomposed and processed through the liver.

About 95% of alcohol is detoxified by liver, but the ability of liver to decompose alcohol is limited, and a considerable part of alcohol is converted into acetaldehyde harmful to human body under the action of alcohol dehydrogenase in liver cells, which interferes with the normal metabolism of liver. A person who gets drunk once can cause millions of liver cells to die. So the earliest symptom of a person's body is fatty liver, which then leads to fibrosis, and then alcoholic hepatitis. The situation will get worse in the future, forming cirrhosis.

The liver involves many organs in the whole body, with 500 functions. If the function is not good, many organs will also be affected, including immune function will also be reduced. Therefore, the only way is to give up drinking, and some liver injuries (hyperplasia of external fibers) will repair themselves, the changes will get better, and the survival time of patients will be prolonged.

4, digestive tract injury

Most alcoholics like to drink hard liquor. The more hard liquor, the greater the stimulation to the digestive tract. If the digestive tract is stimulated by alcohol for a long time, it may lead to a variety of digestive organ diseases, such as gastrorrhagia, gastritis, gastric ulcer, esophagitis, pancreatitis and so on.

5, respiratory tract injury

Studies have found that excessive drinking will greatly reduce the antiviral ability of the human respiratory system. Compared with people who don't drink, the incidence of tuberculosis in alcoholics is nine times higher. Excessive drinking such as tuberculosis and bronchiectasis can also lead to hemoptysis due to the stimulation of alcohol.

6, induce cancer

Excessive drinking is most likely to cause nutritional deficiency in the body and dissolve mucin on the surface of digestive tract mucosa, so that carcinogenic pollutants, such as residual pesticides, arsenic, nitrosamines and mycotoxins, are more and more absorbed by the human body. Coupled with the reduced detoxification function of the liver, carcinogens play a role. In this way, more and more acetaldehyde is produced in the body, which increases the chance of cancer, and finally makes more and more cancer cells in the human body, and promotes the spread of cancer cells throughout the human body.

7. Cardiovascular damage

Although a small amount of drinking can protect the cardiovascular system, long-term drinking can easily lead to cardiovascular damage and cause heart disease. Fatty degeneration will occur in the heart under the long-term stimulation of alcohol, which will weaken the elasticity and contractility of the heart, thus inducing various heart diseases. In addition, if you drink a lot of beer for a long time, it may also lead to an enlarged heart, which is called "beer heart" by the medical community.

8. mental illness

Long-term alcoholism will lead to serious damage to human brain cells, which may lead to mental disorders such as alcoholic psychosis and toxic hallucinations, especially for long-term alcoholics over 50 years old.

9. Hypofunction of blood

After alcohol enters the human body, it can be directly absorbed by the stomach without going through the digestive system. When passing through the mouth, a small amount of alcohol is heated and colored, and enters the blood through the trachea and lungs for systemic circulation. Over time, the function of blood will gradually decline. , can cause hyperlipidemia, alcohol oxidation can also cause hyperlactemia. Therefore, it is easy to make people anemic and increase the chance of being infected with the virus. People who drink too much for a long time are prone to cyanosis or bleeding, which will also increase the risk of hypertension and stroke.

10, leading to osteoporosis.

Excessive drinking for a long time will lead to abnormal metabolism of nutrients, unbalanced metabolism of calcium, decreased absorption capacity of calcium in food, "migration" of a large amount of bone calcium and a significant increase in urinary excretion of calcium, which will lead to serious calcium deficiency in bones and eventually lead to osteoporosis. Many documents show that long-term overdose will make the femoral head "brittle", that is, alcoholic femoral head necrosis. The damage of alcohol to bones often varies from person to person, and there is a process and degree.
