Standing up too fast

[banana87]

Over the past week, everytime I go from sitting to standing I see black stars (not completely over my vision, just at the top and bottom) and go all hot. I've taken my BP and its on the low side of normal, but not worryingly low. Do I have a brain tumor???

Brain tumour unlikely. Try postural hypotension instead.

It probably is to do with your lowish BP. I have low BP and have had this all my life.

But, if it's new to you and it's happening every single time you stand up, I would see the GP. It really, really doesn't sound like a brain tumour :)
