Small amounts of alcohol generally have a relaxing and exhilarating effect, a general feeling of well-being spreads, fears are reduced and sociability increases. The consumption of larger amounts can lead to balance and speech disorders, visual disturbances (double vision or tunnel vision), stomach pain, nausea to vomiting, headaches (hangover) due to dehydration, loss of control and blackouts. There is a risk of accidents due to overestimation of one's own abilities and reduced ability to react. High doses can lead to hypothermia or overheating, deep sleep and coma. Very high doses (blood alcohol concentration of 3-4‰) can be life-threatening.
Attention binge drinking:
Binge drinking, i.e. the consumption of a large amount of alcohol in a very short time, causes the blood alcohol content to rise particularly quickly and strongly. This can quickly lead to alcohol poisoning. Consequences can be: comatose state, memory lapses (film tears), deactivation of important reflexes (danger of choking when vomiting, danger of freezing to death when cold) as well as epileptic seizures. There is also an increased risk of thrombosis, high or low blood pressure, respiratory depression and sudden cardiac death.
Since alcohol is a cytotoxin, regular heavy consumption can have consequences such as damage to all bodily organs, deficiency symptoms, disorders of the nervous system, coordination of movement and memory functions, and even alcohol-induced dementia. Alcohol is a co-carcinogen, i.e. it significantly increases the carcinogenic effect of other substances (e.g. nicotine).
Alcohol can produce a dependence with psychological and physical symptoms. Typical withdrawal symptoms are trembling, sweating, nausea and vomiting up to epileptic seizures. On a psychological level, irritability, anxiety disorders, depressive moods and hallucinations may occur. Tolerance develops with regular consumption.
