Hello and welcome to Healthcare Magic. Thanks for your query.
I understand that you must have gone through a very difficult time during your son's major health set back and it's quite natural to try to make sense of what had happened.
Considering the facts that he had taken excessive alcohol, was in an altered state of consciousness, had 'rattling' of the body and was foaming in the mouth, it appears that he could have had a seizure
(fit). Seizures are associated with alcohol withdrawal
as well as in acute toxicity. So the foaming could have been a sign of a preceding seizure, rather a 'sign of death'. However, it could have lead to fatal consequences, if immediate medical attention had not been given.
Since a major probable cause of your son's problem was his alcohol consumption, I would suggest that you encourage him to seek help for his drinking problem. There are effective ways to help him overcome this, by means of counselling
) or medication.
