maybe u have low blood pressure caused by lower calorie intake..

Just low blood pressure- it's called Orthostatic Hypotension, and could have many causes, most are harmless. If you ever pass out, go to a doc What happens is, there are little pressure receptors, Baroreceptors, in your arteries, and when you stand they don't function normally, so they don't tell your heart to beat faster right away. Instead, the blood begins to pool in your legs as it leaves your head (Gravity) and you get that blindness. Then the baroreceptors realise what's happening, tell your heart to work harder to get the blood up to your brain, and you're fine! In normal people, this sensing of pressure and making the heart work harder happen upon standing, not afterward.

ok this happens to me al the time. when your sitting or lieing down the blood going to your brain slows down. but when you sat up really fast then the blood has to speed up and your light headed for a sec or two. so try not to get up so fast sit up before standing up also before walking after you get up stand for a sec so the blood can reach your brain.

I have that same thing too - I call it the Momentary Loss of Vision. Don't worry, it happens to me all the time, like now, I looked away for a moment while answering you, and it happened



I'm not sure what makes it happens, but my friends thinks its cool like 'matrix-vision'

Do you live in a house designed for midgets? Are you banging your head on the ceiling, what's wrong you a giant or something?



Just kidding.

This is exactly what happens to me. Although I can't quite remember why it happens, you should defiantly up your water and sodium intake.

You're standing up too fast.

There's a large blood rush in people when this happens and they temporarily lose sight, it happens to me sometimes.

Just, stand up a little slower.

you probably have Low blood pressure. try getting up slower and if it gets realy bad sit with your head btwn your knees.

or ask a docter.
