Today we will talk about the effects of alcohol on the human body, what harm it does to health, and you will learn some interesting facts about alcoholic beverages.

Using alcoholic beverages has become a tradition. So people fight bad moods, have fun, celebrate joys and drown out sorrows. But only a few people think about the devastating effects of ethanol on the body.

It is necessary to take alcoholic drinks in moderation and watch your state of health during meals. Alcohol-containing products are addictive and hard to fight.

The harm of alcohol on the human body: health consequences

Alcohol contains, in its composition, harmful impurities - ethers, liquor oils, aldehydes, free acids. These components adversely affect human health.

Alcoholic beverages gradually destroy cells and tissues, causing dependence. Under attack are almost all systems of the body. So, about the harm of alcohol in brief, the most important.

Cardiovascular system

According to statistics from cardiologists, every second person diagnosed with alcoholism has a damaged cardiovascular system. Alcohol from the stomach enters the bloodstream, where it begins with its destructive effect.

When alcohol-containing drinks are consumed regularly, the red blood cells are gradually destroyed. Deformed red blood cells are less able to transport oxygen from the lungs to the tissues.

Even a moderate drinker can experience cardiovascular disease by the age of 35-40. Common diagnoses are arrhythmia, vascular atherosclerosis, and coronary artery disease.

Regular consumption of alcohol leads to dysregulation of blood sugar. Increased or decreased blood sugar levels can lead to diabetes, vascular problems, nervous system malfunction, and brain cell destruction.

The brain and the nervous system

In the brain, the concentration of alcohol is higher than in the other organs and systems. The cerebral cortex gradually breaks down.

Regular excessive alcohol consumption affects the nervous system. Problems with memory and concentration of attention appear, mental development slows down, perception of the world around is distorted.

The psyche is broken: the person gradually loses the ability to adequately respond to what is happening.

The liver

The liver is the most vulnerable to alcohol. It is in it that the process of oxidation of ethanol to acetaldehyde occurs - a toxic and dangerous substance. Under the influence of ethanol liver cells die, in their place there are scars. This leads to further disruption of the metabolism.

Regular consumption of alcohol-containing drinks leads to cirrhosis of the liver. This is a disease in which the liver shrinks in size, blood vessels are compressed, and blood pressure rises. If the numbers are too high, they can rupture vessels and cause bleeding that leads to death.

Respiratory system

People diagnosed with first stage alcoholism have impaired respiratory-exhalation cycles. The minute the volume of breathing increases, breathing becomes more frequent. As the disease progresses, bronchitis, pulmonary emphysema, tracheobronchitis appear.

Gastrointestinal tract

People with chronic alcoholism develop diseases related to the gastrointestinal tract.

Gastritis, stomach and duodenal ulcers, pancreatitis, disorders of salivary gland secretion are consequences of alcohol abuse.

The harm of alcohol to women

The female body reacts differently to alcohol than the male body does. Women’s body weight is usually less than men’s, so the dose of alcohol that causes poisoning is less. If a girl drinks regularly, irreversible, dangerous changes occur in her body.

1. Hormonal malfunctions

The work of the human body is regulated by the hormonal background. Alcohol also affects the production of hormones: in high doses, it has a detrimental effect on the adrenal glands. Because of the toxic influence, male hormones are actively synthesized. The result is a predominance of masculine outlines:

  • the timbre of the voice becomes coarse and hoarse;
  • the movements become harsh and angular;
  • The body becomes unattractive, stooped, sometimes with signs of obesity.

In women with alcoholism, menopause occurs 10-15 years earlier than expected.

2. External changes

A girl who drinks regularly can be recognized by her face. Because of the constant swelling and hangover, hyperemia progresses: the blood rush to certain areas becomes greater, and to the rest decreases. Vascular lattice appears on the skin, redness, the whites of the eyes become dark because of burst capillaries.

A hangover can lead to dehydration. Because of this, dark circles appear under the eyes, and liver damage leads to yellowing of the skin. Because of the predominance of male hormones in the body fat is deposited in the abdominal area. Often a noticeable dark down appears above the lip.

Veins lose their elasticity prematurely. Vascular spider veins appear, and you feel pain and heaviness in your legs.

Women who abuse alcohol impair the assimilation of nutrients. Signs of avitaminosis appear - hair becomes dull and brittle, nails break. Girls feel constantly tired for no apparent reason.

3. Infertility

Alcohol abuse leads to infertility. Alcohol causes fatty degeneration of ovarian tissue, which causes problems with ovulation or anovulation. Even if fertilization of an egg has occurred, the toxic effects of alcohol can change genetic information.

Ethyl alcohol changes the structure of the endometrium, the inner layer of the uterine wall. Because of this, a woman cannot bear a fetus normally, the risk of miscarriage increases.

The harm of alcohol for men

The body of men from alcoholic beverages suffers no less than that of women. The major blow falls on the reproductive system. So how does alcohol affect the male body?

1. The male hormone, testosterone, is secreted worse

In the chest and hips forms a layer of fat, which is characteristic of the female type of figure. The muscles become flabby and bags form under the eyes.

2. Potency problems

Men who regularly abuse alcoholic beverages have problems with libido. Alcohol works insidiously: at first it helps to loosen up with a woman, arousal increases, the intercourse lasts longer. But over time, impotence develops, the guy can not satisfy his woman.

3. The activity of sperm decreases

With regular consumption of alcohol in large quantities, men develop another problem - they can not conceive a child. This is because of the gradual shrinkage of the testes, due to which the sperm does not mature. Even if an alcoholic man conceives, doctors give a tiny percentage that the baby will be born without abnormalities.

The sperm cells are renewed every 3 months. It is not recommended to drink alcohol for 4 months before conception. Beer, even in small quantities, is also forbidden.

The effects of alcohol on adolescents

It is forbidden for teenagers to drink alcohol. Their body is developing, and the detrimental effects of ethanol can lead to serious disorders.

1. Impact on learning

The child stops doing lessons, his concentration decreases. At school, he does not assimilate the information, does not do his homework, does not develop his memory.

The teenager lags his peers into development and eventually degrades.

2. Changes in the psyche

When children regularly drink alcoholic beverages, their mental health deteriorates. Teenagers show unreasonable aggression, react inadequately to the remarks of teachers or peers.

3. High probability of developing alcoholism

If a person is addicted to alcohol at school age, he or she has a 70% greater chance of becoming an alcoholic. Not only strong drinks but also low-alcohol drinks lead to dangerous consequences.

The adolescent body is more susceptible to the harmful effects of alcoholic beverages. It needs small doses of ethyl alcohol for intoxication or intoxication to occur.

The harm of alcohol to others or to society

Alcohol use also takes a significant toll on society. Manifestations of abuse reach those who lead healthy lifestyles as well.

1. Domestic Violence

One of the worst consequences of consuming alcoholic beverages. A family with at least one alcoholic suffers from his or her addiction.

Unmotivated outbursts of aggression, an unfavorable environment, and scandals lead to discord. Such families often fall apart. If the relationship is tried to maintain, the non-drinking party usually suffers from it.

2. Crimes

Theft, murder, rape, and trespassing on private property often occur under the influence of alcohol.

3. Conflicts on the street.

Fights, which can end in death, occur because of large amounts of alcohol.

A person under the influence of alcohol is out of control: he or she can severely injure the other party to a conflict who may not even have been drinking hard liquor.

4. Demographic problems

Alcohol affects the reproductive system of women and men. Among alcoholics, there is a large percentage of infertility. Even if such a couple gives birth to a child, in most cases, he will be distinguished by problems in development.

How much alcohol you can drink without harming your health

Let us immediately disappoint all lovers of alcoholic beverages. Dr. Lars Moller, Program Manager of the WHO Regional Office for Europe for Alcohol and Illicit Drugs, states that there is no safe dose of alcohol.

Lars Moller also says that there is a level of consumption at which the harm is minimal, but the WHO does not give clear values, as alcohol is associated with many diseases and it is better to give it up altogether.

For women, the permitted daily dose is equal to a glass of wine or 0.3 liters of beer. While men can afford only two glasses of wine or a shot of spirits (cognac or vodka), or only 0.6 liters of beer per day.

Despite all the recommendations, remember one simple rule: the less alcohol you drink, the better.


Excessive alcohol consumption is dangerous for the human body. The gastrointestinal organs, cardiovascular system, liver, respiratory organs, and reproductive system are all subject to the harmful effects of alcoholic beverages. It is strictly forbidden for teenagers to drink alcohol.

Alcoholism leads to negative consequences for society: crime rate grows, demographic background worsens. Alcoholic beverages can be drunk in moderation, only in this case they can bring benefit to the body, but this issue has not been enough studied by researchers so far.
