Why do I feel like blacking out when getting up?

almost everything time I get up to walk somewhere everything turns black for like a minute and I get this quick rush headache what is up with that?

I dont know I just think that you should go see the docter cause it may be series.

You might need to see a doctor. It could be something as simple as not eating or being dehydrated.
It could be something as serious as a heart palpitation.

you could have low blood pressure

Yeah LBP or maybe anemia? you really should see a dr... passing out while doing something could be dangerous (like driving...)

it very well could be that you are anemic. that was happening to me and I went to the doctor. it was fixed with simply taking iron pills...
