Hypoglycaemia Coma?
An extremely healthy 26 year old friend of mine who doesn't have any serious health issues nor diabetes... Fainted a few hours ago and when we brought him to the hospital the doctors said he went to coma from hypoglycaemia... He hasn't got any brain damage luckily!
Will he be able to wake up in 2-5 days?

If the docs are saying so it is likely that his coma might be partially induced for medical reasons. So there is no reason not to believe them. It seems clear that psychological therapy will have to be brough to bear to reverse the eating disorder that has been starving him of adequate blood sugar. That of some serious dietary or substance "Issue."
