So earlier today I was at this pizza place with my dad, sister and uncle. I ate the pizza and was sat there a while afterwards as we weren't in any kind of rush, and then when we got up to leave I stood up and about a second later my vision blurred and I lost my balance (not visibly enough for the people around me to notice, and I was back to normal a second or two later, but I explicitly remember my vision blurring and me not feeling stable on my feet). I know it wasn't due to lack of sleep (I had a solid 8 hours last night) and as such I'm unsure as to what may have caused it. Should I be worried about this or does anyone else get this from time to time?
