Hello,
Excessively drinking alcohol will cause you to urinate quite a bit and lose large water volumes over a short amount of time.
This could contribute to blacking out spells. Of course, blacking out from drinking excessively can simply be from how the
CENTRAL NERVOUS SYSTEM (CNS) behaves under the influence of ALCOHOL which is a DEPRESSANT type of chemical.
In other words, maintaining a state of alertness after having drunk excessively is difficult and people can just pass out from overly concentrated the chemical in the bloodstream.
Stating that you are in "premium shape physically" but drinking excessive amounts of alcohol is non-sequitur.
Excessive alcohol intake over time will weaken the heart and lead to early congestive failure weakening of the
cardiac muscle which cannot be reversed and damages the central nervous system which in the long run can lead to dementing illnesses and alterations in behaviour and personality.
Working out above average amounts does not confer any degree of protection to the organ systems I've mentioned.
Therefore, my suggestion is that you seek assistance in overcoming your habit of excessively drinking otherwise, you are at high risk of losing your premium physical shape.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Dariush Saghafi, Neurologist
