I am 12 years old perfectly healthy, i drink lots of water,I am not overweight, and I play many sports, so why do I pass out randomly? So far since summer I have only passed out three times but each time was out of the blue and completely random. The first time was when I was babysitting (but thankfully my older brother was there and he knew what to do), the second time was when I was sitting down and I tilted my head back a little then passed out and the third time was yesterday at a party with my friends and they were able to help me but it was scary. If it helps I get dizzy when I stand up a lot of the time and I have to sit back down. Can anyone tell me what's happening?
Sounds like blood pressure problems possibly, you need to speak to a doctor about this because honestly if you were perfectly healthy you wouldn't be having blackout spells in the first place.
passing out means either blood circulation problems or oxygen intake problems
both very concerning, you should see a doctor about this :O
What are your parents doing about it? Are you telling them what's going on?
