I just blacked out/fainted! What could this be from? Dizziness. HELPP!!?!


Question: I just blacked out/fainted! What could this be from.? Dizziness. HELPP!!.?
So I woke up and had a 90 cal granola bar (so I did eat)
and i layed down and stuff. and then i stood up to go to the bathroom (everytime i stand up i always feel dizzy), and i felt a little dizzy like always. and the next thing i knew i was on the floor. i blacked out!

im so scared now. thats never happened before. and now my mom is freakin out that it has to do with me not eating enough/going back to my old ways ( i was hospitalized 1.5 years ago for eating disorder)

but i eat 1200 calories a day, ALL healthy. no fast foods, no oils, no grease/fried. all veggies, fruits, salads, grilled chicken, whole grains, whole wheat bread, everything good.

and i exercise 6 times a week.
will i be able to exercise later.? i NEED to run 3 miles, crunches, pilates. and its 10:30 am now, ill do this at like 2pm.
will it be fine then.?


but the main thing is, WHY did I pass out.?.?.?.?
when I was in middle school i had hypoglycemia..could it be that.? and how would i check my own blood pressure.?

thanks!

Answers:
Low blood sugar, low blood pressure, or something more serious that could be developing. You may actually need a little fat in your diet, or more likely have a vitamin deficiency. Time to get it checked out by a doctor.Health Question & Answer

It may be your blood pressure, when it drops to fast or even over a period of time then it can cause this. I also had hypoglycemia when I was younger and you have to make sure that you get some kind of sugar(since it also may have to do with your blood sugar) in you.Lots of luck and I hope you feel better fast!Health Question & Answer
