feeling lightheaded

So I just recently started working out with a trainer and I am frustrated because for the last few weeks I feel lightheaded when working out with him and I have to slow down. I'm curious as to what could be causing this. I have a call into my doctor but I figured I would ask on peertrainer in the meantime.

My background is... I'm a relatively healthy person. Eat well rounded healthy meals, take a multivitamin, I'm 26, and I exercise often, mostly running.

Any thoughts?

You should be eating carbs an hour or two before you work out really intensely. Are you doing that?

No I haven't been doing that. I've got a protein/carb bar i'm going to try today.
150 cal
23 g carbs
13 g protein

It could be that...
- you've undereaten
- you're not breathing right for the exercises you're doing
- your blood pressure fluctuates a lot

I have high blood pressure (but it is controlled w/ medication-and i am now normal) and when my blood pressure gets low and tries to correct itself I get dizzy/lightheaded (sometimes happens in yoga when I go from a low position to standing up fast, or after lying down for a while and getting up too fast, but some exercises cause this to happen to me also).

It may be a medical issue, or you may just not be eating enough to sustain you before hand.

Is the blood pressure medication a beta blocker? Those kinds prevent your heart rate from increasing in response to exercise and posture changes. It's a good thing you will be seeing your doctor. There are lots of other bp meds out there that don't have that effect. If you are on something other than a beta blocker, then maybe your doc might want to adjust the dose.

To the OP - do you take any other vitamins or fat burners or anything?
I had gotten some "vitamins" with Billy Blanks Boot camp dvds. They say to take before exercise, but when I did I got lightheaded and almost nauseous.
I think they had caffeine of some sort. Anyway, I stopped taking them and the problem went away.
