lately all the time i feal dizzy for a few moments, most of the time its like when i stand up or sit or have just gone up the stairs
like really really dizzy and lightheaded, like makes me lose my balance alot of times and sometimes it happens when i just walking like the earth just tips to its side for a moment and makes me fall over
aney idias on whats going on?

yep, I have this all the time; it sucks.

is it hot where you are? that ca be a major factor, because I did't get dizzy any more, but now it's happening all the time cos of the hot weather; try not getting up too fast;

have you blood pressure checked; I had a very low blood pressure, which is why I alway got dizzy (I even blacked out once because of it when I was getting ready to go down the stairs, so I fell a whole flight of stairs = painful!! )
so because of that I have to eat a lot of salt

go.to.the.doctors.

It sounds like low blood pressure, but obviously non of us are doctors. If it is low blood pressure, it's usually your blood pressure not being able to correct itsself quick enough once you do what you're doing, i.e getting up out of a chair/stairs ect. ect. I'd see your GP.

It really might not be that serious.

Make sure you're eating and drinking enough water.
