What could cause blackouts for a teenage boy?

A 16 year old boy has blackouts, that to him seem to last seconds but he can be like this for up to half an hour. Of course he doesnt remember it... He just blinks and he's in a different place. What could this possibly be?What could cause blackouts for a teenage boy?
The questions you need to find out are:


When do these blackouts happen?


Are they:


a. first thing in the morning when he gets out of bed


b. when he's been sitting or laying for awhile and he stands up


c. In the morning when he's taking a hot shower


d. after he's been active and sweating quite a bit


e. right after he's eaten a big meal


f. all/some of above


g. none of the above





Does he every lose control of his bowels or bladder?


How many glasses of water, sports drinks, milk does he drink every day? Carbonated drinks and juice don't count.


When did these ';blackouts'; start? Does he have any other symptoms... i.e feeling his heart racing? feeling dizzy? does it start with his vision going black and then he passes out? Since you didn't mention it, I'm assuming he's never had a shaking or jerking movements when he's passed out?





What could cause blackouts for a teenage boy?
It is hard to say what it could be. There is any number of things that it could be. Some things that it could be: not enough sugar, or too much sugar as in diabetics, a congenital problem, too high or too low of blood pressure, too high or too low of heart rate, if he had been hurt, used drugs or something like that.
Low blood sugar-he could possibly be a diabetic.


I know a guy who used to black out all the time and not remember a thing, sometimes for an hour or so, because he didn't have his diabetes under control.



You might also have him checked for Epilepsy. Myself, I usually have the other type of episode, but have had stuff like he's having happen a few times.
This sounds very strange, but it could be either narcolepsy (where one suddenly becomes unconscious, then wakes up like your describing) or maybe an epileptic??
GET to a doctor/Neurosurgeon, asap!!!!!!!!!!!!!!!!!!!
