Alcoholism is a chronic disease that develops as a result of regular and long-term abuse of alcoholic beverages with the formation of mental and then physical dependence on them. In a biological sense, alcoholism is an incurable disease. This means that there is no medical remedy that would restore the patient's ability to control alcohol consumption. An alcoholic is doomed either to a progressive deterioration in health and social status, or to complete sobriety.

Alcohol abuse is an extremely pressing problem all over the world, posing a serious threat to the health and social well-being of the population. Alcohol or alcoholic beverages contain ethanol, a psychoactive and toxic substance that can cause addiction. Statistics from the World Health Organization show that about 3.3 million people die every year from the harmful effects of alcohol. More than 75% of these deaths are men. Among young people aged 25 to 39, the number of deaths due to alcohol consumption is about 25%. This figure increases every year, and the age of people suffering from alcoholism decreases. In 2020, Belarus ranked 27th in the world ranking of drinking countries. According to WHO, the average Belarusian, starting from the age of 15, drinks 11.2 liters of alcohol per year. National statistics, focusing on all groups of the population, speak of 9 liters.

There is no safe form of alcohol consumption. Even low levels of alcohol consumption are fraught with certain risks and can cause harm. A dose of alcohol in the body of 0.5 ppm is alcohol intoxication, a level above 3 ppm is considered a real threat to life.

The development of alcoholism is the result of the interaction of many factors. The risk of developing chronic alcoholism depends on:

  • depending on individual characteristics - young people, children of alcoholics, women, and people who drink alcohol to relieve emotional tension and stress are at greater risk;
  • from age – the earlier alcohol abuse begins, the faster the addiction develops;
  • from the amount of alcohol consumed.

The following signs of alcoholism are identified.

  • The first sign is a primary pathological attraction to alcohol, a desire to consume it in a certain rhythm.
  • The second sign of early alcoholism is the growth of tolerance to alcohol, the ability to tolerate a certain dose of the substance. Healthy people are usually satisfied with consuming 100-150 ml of strong alcoholic beverages, and with an alcohol overdose they experience nausea and vomiting. Alcoholics are able to consume much larger doses of alcohol without any protective reflexes.
  • And the third sign is the loss of control over the dose. A healthy person experiences a feeling of satiety during alcohol consumption. A sick person drinks a certain key dose and develops an irresistible desire to continue drinking further. Control over the dose is lost, if drinking continues after several years, any amount of alcohol will cause severe excess or binge drinking.

There is a misconception that drinking low-alcohol drinks does not cause significant harm to health. In recent years, especially among young people, so-called beer alcoholism has been gaining momentum. Beer has become a popular drink for many reasons, including its relatively inexpensive price. Many people mistakenly believe that if beer is a low-alcohol drink, then it does not have a significant effect on the body, and therefore is safe. Due to the low concentration of alcohol, it is drunk in larger quantities than vodka or wine. However, beer, like all low-alcohol drinks, is by no means a harmless thing. Alcoholism due to beer consumption develops 3-4 times faster than from strong alcoholic drinks.

Alcohol abuse is associated with a high risk of medical and social problems. First of all, alcoholism has a negative impact on human health. Alcoholic beverages affect absolutely all systems and organs without exception, weaken the immune system, and lead to frequent illnesses.

The most significant of these are:

  1. Immune system disorders: alcohol consumption leads to a decrease in the production of lymphocytes, contributes to the development of allergic reactions, and disrupts the processes of hematopoiesis;
  2. Muscular dystrophy, cramps, numbness and weakness of the limbs, paralysis of individual muscle groups,
  3. Skin diseases (boils, ulcers, pustules, allergic rashes);
  4. Cardiovascular diseases: damage to the heart muscle, enlargement of the heart; heart rhythm disturbances; arterial hypertension; ischemic heart disease; heart attacks;
  5. Respiratory diseases: tuberculosis, bronchitis, tracheobronchitis, pulmonary emphysema;
  6. Diseases of the gastrointestinal tract (gastritis, gastric ulcer and duodenal ulcer), liver (fatty degeneration, alimentary-toxic hepatitis, cirrhosis), pancreas (pancreatitis, diabetes mellitus), kidneys (impaired excretory function of the kidneys caused by malfunctions of the hypothalamic-pituitary-adrenal system and destruction of the renal epithelium). These diseases doom people to constant pain and suffering. In addition, pancreatitis can worsen even with a minor violation of the diet;
  7. Effect on the central nervous system: visual impairment (diplopia, glaucoma, optic nerve atrophy), degradation of the cerebral cortex (failures in the functioning of the vestibular apparatus, degeneration of neurons, damage to the centers responsible for memory and human behavior), epilepsy, psychosis due to alcohol withdrawal, dementia/senility, encephalopathy;
  8. Patients with chronic alcoholism may be diagnosed with a wide variety of mental disorders: hallucinations, depression, aggression;
  9. Reproductive system failures: both potency in men and fertility in women are reduced. Alcohol consumption by a woman expecting a child can lead to the development of fetal alcohol syndrome and complicated premature birth. Children are born with mental retardation and various chronic diseases.

Recently, causal links have been established between alcohol consumption and the incidence of infectious diseases such as tuberculosis, as well as the course of HIV/AIDS.

Alcoholism entails unfavorable psychological and social consequences. The main meaning of life for a person with this addiction is to satisfy an irresistible craving for alcohol. As a result of alcohol abuse, the range of interests narrows, labor productivity decreases, and moral, ethical and mental degradation of the individual occurs.

Ultimately, alcoholism leads to early disability, premature aging and a significant reduction in life expectancy by an average of 15-20 years compared to the life expectancy of a non-drinker.

Alcohol abuse causes deterioration of the general health of the country's population and has a negative impact on family relationships. The consequences of such influence include: a decline in material well-being as a result of a decrease in the ability to work of a family member suffering from alcoholism, family breakdown, neurotic state of wives and husbands (in 70%); deep neurosis of family members, which can only be relieved by medical intervention (50%); the birth of unhealthy offspring; psychopathization and developmental delays in children; children whose parents suffer from alcoholism ending up in antisocial youth groups; the phenomenon of alcoholism infecting the immediate environment (one alcoholic "infects" 5-7 people with alcoholism during his or her lifetime).

When intoxicated, a person loses control over himself, which can lead to injuries at home and at work, accidents, and mishaps.

The consequences of alcohol abuse also include an impact on crime rates – 25% of illegal actions (theft, robbery, particularly serious crimes) are committed while intoxicated.

The fight against drunkenness and alcoholism is an important area of ​​state policy in the Republic of Belarus. Belarus has the State Program "Public Health and Demographic Security" for 2021-2025, which includes subprogram 3 "Prevention of Drunkenness and Alcoholism, Protection of Mental Health", which regulates the prevention of alcoholism and the fight against it. The expected results of this program are: reduction of alcohol consumption to 9.8 liters per capita per year; reduction of mortality from alcoholism; increase in the coverage of rehabilitated persons (up to 10%); reduction of mortality from suicides.

To implement this program, a set of measures is being carried out aimed at:

  • bringing the structure of alcohol consumption in the country to the level recommended by WHO (the “southern model” of consumption with a predominance of beer and natural grape wines);
  • improving the culture of alcohol consumption (including through information and educational events);
  • a gradual transition to drinks with lower levels of harmful substances;
  • the transition of some consumers to non-alcoholic beverages (non-alcoholic beer and wine are a global trend of intensive consumption growth);
  • the growing importance of public health in the national value system of Belarusians (86.9% of Belarusians consider health to be one of the five most important values);
  • growth of the population’s well-being: the higher it is, the greater the attention to one’s own health;
  • limiting the availability of strong alcoholic beverages in particular;
  • promotion of a healthy lifestyle.

Alcoholism is a serious problem that has a negative impact on the physical and mental health of a person and society. In our country, a number of measures are being taken to help prevent drunkenness and alcoholism - providing accessible treatment programs, regular information campaigns in the media, regulating the availability of alcohol to various categories of citizens, etc. However, only a conscious refusal of alcohol will help maintain your own health and the health of the nation. Sobriety is the key to health and longevity. Our health is in our hands.
