Hello. I am a teenager and have been having quite bad dizzy spells nearly everytime I stand up. I am healthy and have no other problems. I don t believe that I am standing up too fast but maybe I am. My vision blacks out when I stand up as well and I am forced to lean heavily on something. I am just wondering if there is any other besides being anemic that might explain this. This has been going on for several months now. Thank you.
Hello. I have been through your question and understand your concern. The complaints you are experiencing are quite common and are reported when standing up very fast. This happens because for that short moment there is less blood going to your head causing these symptoms. Generally you should not worry.  Chat Doctor.  But, if it persists and becomes troublesome then you should consider orthostatic hypotension. Basically, you should get your blood pressure measured by your GP while being fitted and once you stand up. This would just confirm such an eventuality. Still, I don't see anything to be worried about.
