Thank you! Really appreciate this information!

@PistolI don't know what is happening when I stand up because I haven't been tested. My former PCP just told me it was likely blood pressure dropping, but she never tested to see what was actually happening. I do often feel like my heart is racing but I don't know what the actual HR is because I can't measure it.

Can a PCP test this with a blood pressure cuff or would i have to do the tilt table test? Thank you so much. 

Is there anything else that can be done besides those things (fluid, salt, compression stockings)? The dizziness has been getting worse and more frequent lately and I'm not sure what to do. Thanks so much for the quick response. 

Hello, I'm new here and stumbled on this forum. 
I've had issues with getting dizzy every time I stand up since I've been a teenager and it's been getting a lot worse lately (I'm 30 now) where I end up on the floor for a few minutes until I feel okay enough to stand. It's much worse in the summer/when I'm hot. I've had a Primary Care Physician a few years ago tell me that it's orthostatic hypotension and that I should make sure to drink enough water/add salt/maybe wear compression salt, but she told me that based off my symptoms and I think she gave me that diagnosis because my resting BP is relatively low. (usually about 100/60). She didn't test my BP when sitting/standing or anything like that. A friend of mine who is a doctor in another state recently asked me if I've ever done a tilt table test and I said no, what's that? and she said she's surprised I haven't. 
So I guess my questions are (1) should I? and (2) if yes, how does one go about getting one? I don't have a regular primary care physician right now. my last one sadly left my city and I haven't found a new once since.
