weeks or so I have been getting dizzy and light headed nearly every time I stand up. At first I thought maybe I should eat a little more but that didn't seem to help and often even when I have just eaten I still have the same symptoms upon standing. (Believe me, I am not starving myself-I am trying to eat very healthy and have lost some weight-but have been trying to lose and am using ww which I know is healthy) It doesn't last long at all but is annoying. A couple of times I have had to sit down to get it to go away but often it will go away on its own within 20 seconds or so. I know it isn't that unusual to have dizziness upon standing but the weird thing to me is how often it has been happening. I would really prefer not to have to call a doctor about this and am thinking I need to give it more time before getting overly concerned and calling the doctor. Any thoughts?
