Intoxication causes alcohol contained in alcoholic beverages. It is absorbed into the bloodstream through the walls of the stomach and intestines. The further action of ethyl alcohol is that it promotes the adhesion of red blood cells, removing the protective layer of the red blood cells (erythrocytes) together with a charge that repelled them from each other. As a result, the blood clots, clots, plugging of small blood vessels, particularly blood vessels of the brain. To them ceases to receive oxygen that is carried by blood, occurs hypoxia (oxygen deprivation) of individual brain regions. This causes diverse changes in the physical and mental state of the person, called intoxication.
So due to intoxication from a medical point of view. The more ethyl alcohol in the blood, the stronger the intoxication and disastrous health consequences. Most unpleasant of all the fact that excessive alcohol consumption causes the addiction then becomes a way of life, and a person deliberately gets drunk in order to forget that he is an alcoholic and another way of life he ordered. Formed a vicious circle.
The mechanism of the psychotropic effects of alcohol on people is very complicated and not enough studied. Behavior and self-perception of the person at different stages of intoxication depends on many factors both mental and physiological nature, in other words, the characteristics of each individual human body and the composition of the alcoholic beverage. However, in General there are four stages of intoxication.
First degree (mild intoxication) is characterized by a pleasant feeling of warmth and muscle relaxation in self-perception observed a feeling of contentment with themselves and the world around you, there is a looseness in the movements and speech. Loss of control leads to the fact that the most shy person becomes cheeky and annoying.
In high degree of intoxication come mood swings, from extreme friendliness to aggressiveness be unpredictable and movements, the person becomes dangerous, both for themselves and for others.
A strong degree of intoxication is characterized by a fuzzy slow speech, wobbly gait, inability to comprehend a complex situation or environment. Mental excitement gives way to depression, sleepiness, which indicates the inhibition of the functions of the cortex and subcortex of a brain. At this stage, a person can fall asleep anywhere: on the street, at the table or in transport.
The fourth degree of intoxication, the most severe, occurs in those whose bodies are already deeply affected by alcohol, it manifests itself in severe disorders during sleep caused by intoxication: cardiac arrhythmias, epileptic seizures, vomiting, involuntary discharge of urine. As a rule, the entire period of intoxication falls out of memory after the return to a state of sobriety.
The cause of all these conditions, of course, is the consumption of alcoholic beverages. But if the first, second and third degree are caused by just different the amount of alcohol consumed, cause intoxication of the fourth degree - the constant alcohol abuse that causes deep mental and physical health that requires serious and comprehensive treatment.
