Alcohol dependence is a recognized illness that occurs when a person can no longer control the consumption of alcohol in everyday life. Alcohol dependence usually develops over a longer period of time and is therefore often only recognized as a problem by those affected at a late stage. There is no precise medical definition of when exactly problematic alcohol consumption occurs. However, as soon as consumption causes problems in everyday life and is noticed by family or friends, it always makes sense to take action.
In order to find out whether an alcohol dependency is present, the amount drunk, drinking behavior and downstream effects of alcohol consumption must be critically examined.
For "risky alcohol consumption", which can cause physical and psychological damage, there are limit values from the German Center for Addiction Issues (DHS) for orientation.
A risky alcohol consumption is therefore deemed to exist if
- women drink more than 12 grams of pure alcohol per day. For comparison:
0.33 liters of beer (4.8 percent alcohol) corresponds to 13 grams of pure alcohol. - Men drink more than 24 grams of pure alcohol per day. For comparison: 0.5 liters of beer (4.8 percent alcohol) plus a 2 cl shot (33 percent alcohol) already equals 25.5 grams of pure alcohol.
The DHS generally advises: You should avoid alcohol completely for at least two to three days a week.
Exceeding the above limits is not yet a sign of alcohol dependence.
An alcohol dependence is only present if at least three of the following characteristics have repeatedly occurred together within the last 12 months:
- A strong craving or a perceived compulsion to consume alcohol
- Difficulty controlling alcohol consumption
- Physical withdrawal symptoms when abstaining from alcohol
- Proven tolerance: larger and larger amounts of alcohol are required to achieve the same effect.
- Increasing neglect of other interests in favor of drinking
- Continued alcohol consumption despite clear evidence of physical or psychological consequences.
