The effect of alcohol on the human body

When there is another broadcast on TV about the problems of alcoholism, we are in a hurry to switch the channel - after all, this does not concern us. Is a couple of liters of beer on a Saturday night with friends - is it alcoholism? Or a gram of three hundred vodka for a good snack? Of course, it's hard to call it alcoholism. The effect of alcohol on the human body

Nevertheless, the negative impact of alcohol on health is impossible only if a person does not drink alcohol at all. All others to one degree or another experience the consequences of drinking alcohol. The saddest thing is that practically no system of the human body remains "indifferent" to even the most harmless, at first glance, doses of alcohol. And reacts to it not in the best way.

Stomach and pancreas

First of all, alcohol has a negative effect on the digestive organs: esophagus, stomach, pancreas. Here, the effect of alcohol on the human body is manifested in damage and destruction of cells of the inner surface of the digestive organs, burns and necrosis of their tissues; atrophy of the glands secreting gastric juice; death of cells producing insulin. This, in turn, leads to disruption of the absorption of nutrients, inhibition of the secretion of digestive enzymes, stagnation of food in the stomach.

Thus, the effect of alcohol on health can respond to severe abdominal pain, digestive problems, gastritis, diabetes, pancreatitis, and stomach cancer.

The cardiovascular system

From the stomach and intestines, alcohol enters the bloodstream - and here the negative effect of alcohol on the human body continues.

Firstly, alcohol contributes to the destruction of red blood cells - human blood cells. As a result, deformed red blood cells are not able to carry oxygen from the lungs to the tissues (and carbon dioxide back), as well as perform a number of other functions. As a result, even a moderately drinking person aged 35-40 years will inevitably encounter diseases of the cardiovascular system: coronary artery disease, atherosclerosis, arrhythmias.

Secondly, the effect of alcohol on health is also manifested in a violation of the regulation of blood sugar. This, in turn, can lead to an increase or decrease in its level. Both of these can lead to irreversible consequences: diabetic conditions, problems with blood vessels, impaired functioning of the nervous system, and the brain.

Thirdly, it is dangerous for the cardiovascular system to absorb a large amount of beer - a seemingly harmless drink, so popular among young people. This leads to the formation of a bull heart - it is also called a beer heart - increased in volume, prone to more frequent contractions. Hence - all kinds of arrhythmias, increased pressure.

Brain and nervous system

Perhaps it is they who suffer most from alcohol. And if the effect of alcohol on the human body for the time being is imperceptible in relation to other organs, then in this case it is more than obvious.

First of all, alcohol is dangerous for the brain because here its concentration is much higher than in other organs. It is for brain tissue that alcohol is particularly toxic - and that is why the state of intoxication with alcohol is so obvious. We are used to calling it harmless, sometimes even poetic, with the words: “relax”, “forget”, “get drunk”, “alcohol dizzy”. In fact, everything is much more prosaic and sad - alcohol leads to the destruction of the cerebral cortex, numbness and the subsequent death of its parts.

The photo of the brain of people who drink is amazing: it is wrinkled, reduced in volume, covered with scars, ulcers, edema, with many dilated (often torn) vessels, cysts in places of necrosis of brain areas.

The effect of alcohol on health is also reflected in the functioning of the nervous system, due to paralysis of the centers of mental functions: problems with memory and attention, perception of the world, mental development, thinking, psyche, drug addiction, personality degradation.

In the end, a large dose of alcohol (1 -1.25 liters for an adult) can lead to a coma, death.

Liver

The liver is also particularly vulnerable to alcohol, since the negative effect of alcohol on the human body in it is enhanced by the oxidation of ethanol to acetaldehyde - a substance that is quite dangerous and highly toxic. Further “cleavage” of acetaldehyde also adversely affects the condition of the liver.

Under the influence of alcohol, liver cells die - a scar forms in their place, which does not fulfill the functions of the liver, which leads to all kinds of metabolic disorders.

The most famous liver disease as a result of the effect of alcohol on health is cirrhosis. What is it like? Over time, under the influence of alcohol, the liver shrinks, decreases in size, which leads to vasoconstriction, blood stasis and increased pressure in them. Natural in this case, rupture of blood vessels leads to bleeding. In most cases, they die from him.

Can alcohol be good?

In the course of numerous studies, the positive effect of alcohol on the human body was proved. Of course, it is possible only in the case of alcohol in small quantities.

So, red wine strengthens the immune system, serves as a good prevention of atherosclerosis, normalizes the metabolism in the body, removes toxins and toxins from it. White wine and champagne are good for a weakened heart system. Mulled wine will support the body with colds, bronchitis, pneumonia. Drinking beer will help reduce the risk of diseases of the cardiovascular system, cancer, Parkinson's and Alzheimer's diseases, slows down the aging process. And even vodka can be useful - it lowers blood cholesterol.

Under what conditions will the effect of alcohol on health be positive? Scientists have deduced the norms, adhering to which, alcohol can be consumed without harm (and even vice versa - with benefit) for health. For men, this norm is 20 g of pure alcohol, for women - exactly half. For example, such a dose is contained in 30 g of vodka, 100 g of wine, 300 g of beer.

Do not forget about the dangers of alcohol and drink only on health!
