low blood pressure

Like Eden, I've noticed a big connection between hydration and light headedness. I, too, have low BP. I only get faint when I'm dehydrated. I've had some scary the-room-is-spinning moments.

+1 for hydration being a factor. I'm a 100/60 person, and I am susceptible to tunnel-vision and dizzy spells, but I really do not think my BP is the culprit. I notice a direct correlation w/ my hydration level and the dizzy spells. The more hydrated I am, the less likely I am to see black when i stand up. I also try to keep up on my iron intake and B12. It seems like the additional iron helps as well, but I can't know for sure. But I do know i *really* have to keep up with my hydration to keep the dizzy spells at bay.

+1 for electrolytes. Hydration is obviously the key but too much water will only make it worse. We are the lucky few who don't have to worry about sodium intake. My BP runs 80-90's/40-50's. Freaks my co-workers out. I have to increase my sodium intake in the summer and before long rides. Orthostatic hypotension is a daily thing for me. I've learned to switch positions slowly and I cannot ride if it is near 90 or above because then I just get dizzy no matter what my position. There are medications you can take. Your doctor may want to do a "tilt-table" test to determine if you need them.

My BP runs about 90/60...and I only get the dizzy spells in the summer when I am dehydrated from training. That is probably the connection.

So I was at the doctor yesterday for my migraines...
I had 4 espressos in the morning, a large energy beverage at 10am, and a diet dr pepper around 1pm.

My pulse was 60 and my bp was 104/70. I feel out of shape!
