Why do I see total black after standing up from a sqauting position ?

Every time I squat down and then stand up again,I see black ,almost resembling a blackout but I don't faint to the floor. Could it be elevated blood pressure? I'm 24 and the only times I can remember seeing black similar to that was during my olden three pregnancies,and I know for sure that I'm not pregnant now! It's really strange .

Rising against the clock can cause you to go past out or even see "black" and yes it's due to the sudden rise of BP. Try rising slower if this still persist consequently I would call your doctor a short time ago to make sure your BP is within check not to high or to low. It's middle-of-the-road for our BP to drop or lower during different circumstances however, if it's causing problems afterwards I would get it checked out.

It sounds approaching orthostasis, that's low blood pressure on standing. You need to check your blood pressure seated and standing. If at hand is a 15 point difference in the top number or your heart rate increases by 15 points you have the condition. See your doctor to discuss treatment.
