Dizzy,,but weird cause?

[Marco]

ok here is the thing, its quite normal sometimes when you stand up from a long seated position, you feel dizzy for a short period of time duo the lack of oxygen in your brain for those seconds.

The problem though i am experiencing, is quite odd.
Sometimes when i just walk, and often many times when i stand up from seated position, i get dizzy and my eyesight is black for a few seconds. Though i almost never lose balance.

What i find weird is, how can it be, while simply walking not after being in seated position, i still get dizzy. I cant imagine when i am walking a long time i suddenly have no/less oxygen in my brain.

So, my question is, what is causing it? second question is: is it normal dizzyness? third question is: how come you actually lose some oxygen in your brain after standing up from a seating position?

anyways, peace, cheers.

only serious answers are appriciated,
thanks

dehydration is the short answer. the longer answer is that the dehydration causes a drop in your blood pressure with a change in position. increase your fluid intake with something that will also maintain your electrolyte balance. if this doesn't help, see a doctor.
