Hello and welcome to Healthcare Magic. Thanks for your query.
A sudden loss of consciousness
followed by a period of confusion may indicate a serious problem. It could be indicative of a neurological problem like a transient ichaemic attack (TIA
) or a seizure
. Alcohol can be the cause of such problems - either due to an acute intoxiation or during a withdrawal state also.
Since heavy smoking
and drinking are major risk factors for many serious diseases, I would advise you to take him for a proper medical evaluation, to be on the safer side. In case his symptoms are indicative of a serious problem, then further preventive measures can be started immediately.
Wish you all the best.
