Drinking alcohol is harmful to human body, especially on an empty stomach. First of all, drinking directly hurts the liver. After alcoholic hepatitis, hepatitis, cirrhosis and liver injury, vision will inevitably decline, and the body's ability to detoxify will also decline, leading to decreased immunity and easy infection with other diseases and tumors. Secondly, drinking alcohol hurts the stomach, has poor digestion and poor physique, and is prone to other diseases. Third, drinking alcohol can also damage the heart, spleen and pancreas, and easily lead to hypertension, cardiovascular disease, stroke and pancreatitis. Fourth, drinking alcohol will damage the kidneys, cause prostatitis and affect sexual function. Fifth, drinking alcohol is harmful to the nerves. People who often drink too much will become dependent on alcohol and have a bad temper. Sixth, drinking is bad for your appearance. People who drink a lot are haggard and their skin is prone to aging. Drinking and smoking, adding poison to poison, will also damage the lungs. So please ask your father to give up drinking, but don't suddenly brake, and slowly reduce the amount of drinking. In addition, you can also make medicinal liquor, such as medlar. You can have a drink every day, not only for health, but also for drinking. One. Drinking too much will cause the following disadvantages: 1. Death: Alcohol can inhibit the respiratory center of medulla oblongata, causing respiratory arrest, and the drop of blood sugar may also be a fatal factor. 2. Malabsorption syndrome causes various vitamin deficiencies, which indirectly leads to various nervous system injuries. Two. Effect of long-term heavy drinking 1. Liver injury: fatty liver caused by accumulation of liver fat. 2. Gastric ulcer: It can cause gastric bleeding and endanger life. 3. Nervous system damage: such as peripheral neuropathy. 4. Cerebral cortex atrophy: It is reported that some chronic alcoholics have cerebral cortex atrophy, and some patients have signs of mental decline. 5. Alcohol fetal syndrome group: the metabolism and excretion of alcohol in the fetus are slow, which causes various injuries to the developing fetus, including fetal malformation, stillbirth, growth retardation and behavioral defects. Three. The influence of alcoholism on family life is 1. Emotional excitability, temper tantrums, poor judgment control, easy to conflict with people, sensitive to external stimuli, and high crime rate. 2. Spouses and children are often the targets of violence. 3. Mental trance affects work efficiency. 4. The alienation of relatives and friends makes alcoholics suffer more frustration and pressure and become more self-destructive. Four. Alcohol has different effects on different people. Most people think that alcohol is a stimulant, however, from a medical point of view, alcohol is a sedative: it will slow down your reaction time and confuse your ability to judge exercise and distance. Even drunk, even walking and talking is a problem. Five. It is important to know that alcohol is a drug and addictive. The more you drink, the more you want to drink, and the more you need to drink to get instant pleasure and happiness from wine. However, this is a vicious circle; Because after drinking it, you will have a hangover and a bad headache. The main reason is dehydration: alcohol allows water to leave your body cells and enter the blood and urine. Not only that, after a few years, alcohol will lead to cirrhosis, and some results will be like brain injury, stomach disease, vitamin deficiency, hypertension, depression and so on. It is very dangerous for pregnant women to drink alcohol. Even if the mother's blood contains a small amount of alcohol, it may lead to mental retardation or other birth defects. Six. The social cost of alcoholism is staggering. Alcohol has caused the loss of millions of working days, which is directly related to many industrial accidents and is usually a factor of suicide. The victims of alcohol are often other innocent people, not the drinkers themselves. For example, drunk driving shows indifference to human life, not only to the driver and his passengers, but also to the lives of innocent people. There are different opinions about whether alcohol is beneficial or harmful to the cardiovascular system. Some alcoholics drink more and more on the grounds that alcohol can pass through blood vessels, and their addiction to alcohol is growing. There is a qualitative and quantitative problem of not knowing the benefits of alcohol on cardiovascular system, that is, drinking a small amount of low-alcohol is beneficial to the prevention of cardiovascular diseases, while drinking a large amount is harmful to health. Some experts believe that the prevalence and mortality of coronary heart disease in a small number of drinkers are lower than those in non-drinkers, which is related to the fact that a small amount of drinking can increase HDL-C in blood and inhibit platelet aggregation. Among many liquors, red wine is superior to white wine and other liquors in preventing cardiovascular diseases. As for the amount of alcohol consumed, it is best not to exceed 50 ml per day. It is reversible that the systolic function of healthy people can be reduced after drinking alcohol. In addition, drinking alcohol can also accelerate the heart rate and dilate peripheral blood vessels, which is unfavorable to some patients with cardiovascular diseases. Some healthy people may have supraventricular or ventricular arrhythmia after drinking a lot. Because it mostly happens after drinking heavily on holidays, this syndrome is called "holiday heart disease", which is caused by alcohol and sympathetic nerve excitement, and can gradually return to normal after abstinence. Long-term heavy drinking will lead to heart failure, which is characterized by enlarged ventricles and low left ventricular systolic function. The appearance and regression of pathological changes are related to drinking. After stopping drinking, heart failure can be improved or at least not further deteriorated, and it will recur after drinking again. If this happens repeatedly, it will cause irreversible damage to the myocardium, even after abstinence, there will be progressive deterioration of heart function, which will lead to "semen cardiomyopathy". In addition, the incidence of atrial fibrillation in alcoholics is also high. This kind of atrial fibrillation caused by alcoholism can be reversed or stabilized if alcohol can be stopped early. Alcohol is a food with pure heat energy. Long-term heavy drinking will increase weight, affect the process of glucose metabolism in the body and increase the production of triglycerides. Obesity and hyperlipidemia are both risk factors for coronary heart disease. Therefore, long-term heavy drinking will increase the prevalence and mortality of coronary heart disease in heavy drinkers. It is not difficult to see that drinking a small amount of low-alcohol wine has positive significance for preventing cardiovascular diseases; Drinking a lot of hard liquor for a long time is extremely harmful to health. In view of the harm of drinking to digestive system, central nervous system and reproductive system, and a series of traffic and social problems that may be caused by drinking, relevant experts suggest not to take moderate drinking as one of the measures to prevent cardiovascular diseases. Advise you not to drink too much, and middle-aged people with drinking habits should limit and reduce drinking; On holidays or when friends and relatives get together, it is advisable to drink low-alcohol wine. Patients with cardiovascular diseases must abstain from drinking alcohol, and children and adolescents should not drink alcohol. In addition to the immediate impact of one-time excessive drinking (commonly known as drunkenness), repeated heavy drinking will also cause a variety of serious long-term diseases. We summarize the effects of drinking on various organs of the human body as follows. A small amount of alcohol in the brain can make people feel excited, alert and focused, but the actual results show that this is not the case. Drinking a small amount of alcohol has a sedative effect, while drinking more alcohol has serious harm to memory, attention, judgment, function of municipalities directly under the central government and emotional response. Drinking too much can lead to slurred speech, blurred vision and loss of balance. Long-term heavy drinking in the liver will inevitably lead to cirrhosis. The diseased liver can no longer handle nutrients from the digestive tract and drugs ingested by the human body. There are many symptoms of cirrhosis, and they are diffuse. These symptoms include edema (fluid stagnation, bloating) and stomach jaundice (yellow skin and white eyes). Skin alcohol is a vasodilator, which can dilate blood vessels on the body surface. In addition to making you look flushed, it will also make your body tissues radiate heat excessively, which will cause you to feel cold (hypothermia) in cold weather. People who drink heavily in the heart will develop cardiomyopathy, which means that the muscle tissue of the heart becomes weak and damaged. One-time heavy drinking in the stomach will make you feel uncomfortable with acute gastritis, and continuous heavy drinking will lead to more serious chronic gastritis. Alcohol in reproductive organs can lead to male impotence. For pregnant women, even a small amount of alcohol will increase the risk of physical defects of unborn babies. How much is drinking too much? The question should be: how much wine is enough to drink? The influence of alcohol on the body and mind depends on its concentration in the blood. Alcohol enters the blood through the digestive system and stays in the blood until it is decomposed by the liver or excreted with urine. The decline rate of alcohol concentration in blood is quite stable. In any case, no matter how long you are affected, as long as alcohol reaches a peak in your blood, it will be excreted from your body as long as alcohol leaves those affected people slower or faster than you. However, the rising speed of alcohol concentration in blood varies from case to case. Therefore, if you want to prevent the excessive increase of alcohol content in blood, you should think of the following factors when drinking. People with big bodies have more blood than people with small bodies. In the case of drinking the same amount, the alcohol concentration in the blood of people with large bodies rises slowly, and its total concentration is relatively low. Eating food in the stomach while drinking will slow down the speed at which alcohol is inhaled into the blood. If you eat while drinking (or eat some food before attending a social gathering), you can temporarily slow down the speed of alcohol absorption. Of course, you also eat more calories. Types and drinking speed of alcohol The slower you drink, the less intense the influence of alcohol. If you drink whiskey, a lot of alcohol will increase the alcohol concentration in your blood, which is much faster than drinking beer. If you take a swig of whisky, its alcohol will be quickly absorbed by your system. If you sip a glass of beer slowly, the alcohol in the beer may have dissipated by the time you finish it. The body's tolerance for frequent drinking will make you gradually "adapt" to the situation that there is a lot of alcohol in your blood, and your brain will "get used to" soaking in alcohol all day. As a result, if you have been drinking for many years, you may be able to drink normally and behave normally on the outside, but if someone who drinks less than you drinks your blood, he will definitely look drunk. The appearance is unreliable. Alcoholics may speak neatly and clearly, but their driving ability will still be impaired and their brains and bodies will continue to suffer. The unfortunate consequence of increasing tolerance is that you must maintain the alcohol concentration in your blood. Moreover, you will gradually need more alcohol to achieve the effect of drinking. It is precisely because of this dependence that some people gradually degenerate into alcoholics (drinking addiction). Another thing to remember is that the alcohol content in the blood is accumulated over a period of time. Eating while drinking, eating food while drinking, and even eating snacks when attending social gatherings can slow down the speed of alcohol absorption, so that the amount of alcohol in the blood gradually increases, and its peak value is lower than that when drinking on an empty stomach.
