Dizziness

[leulamax]

Hey all,
I have a question. I have noticed the whenever I do any heavy exercise (climbing on a bike or uphill hiking), if I have to stop, my heart feels like it is fluttering and beating heavily and I get dizzy and almost naseaous. I am not out of breath really, because I am in decent shape. If I walk around a little bit or put my head down, it will pass within 5 minutes or so. I don't notice this when I am actually doing the exercise, just when I stop. I have my blood pressure checked regularly and it is normally low around 100/65. I don't know if this is something I need to be concerned about or not. Thanks for any input.

Your symptoms sound very similar to what I experienced a few times last year. I was alarmed, but chalked it up to not being used to climbing, heatstroke, bonking, whatever. Since then I've had milder symptoms when at rest, so I'm now having tests done for a heart arrhythmia.

You may want to join in on the Atrial Flutter thread that easterbird began last week, so that we don't have multiple threads on basically the same topic.

When you're actively cycling most of your your blood flow (and therefore oxygen) is directed to your legs. When you stop cycling you need that oxygen in other places but if you stop suddenly it's still mostly in your legs so you may be getting dizzy form lack of oxygen.
That's why we cool down in spin class or before getting off a treadmill.

This should last only a brief time though. If it takes a while to go away or if there is pain involved I would certainly have some testing done.

I read this article a while ago. I'm not sure it's what you're describing, but I thought it might help.

I get dizzy sometimes when standing up, but never while exercising.

I like Dr. Gabe almost as much as Dr. Drew (Dr. Drew is kind of hot)

Well, damn, it's a good thing I didn't read that article two years ago when I had vertigo, I would've convinced myself I was having strokes.

This has been happening to me much more often over the past couple of years. I think in my case it might be migraine-related. I've been cutting down on the dosage of the daily meds I take to manage migraines during that time, and when I stopped taking them completely a couple of months ago, the lightheadedness got much worse. I went back on a low dose of the drugs and that helped.

That could be--I've had migraine issues for years.

I'm lucky that I discovered that routine chiropractor adjustments really do the trick for my migraines, but the dizziness still comes every so often, usually upon standing up in dim lighting (now that I'm thinking about it, it's probably an early warning sign I'm due for an adjustment).

I fell once and hit my head on a steel shelf (due to the dizziness--not a cause of the dizziness) and got a concussion, so that's definitely something to be concerned about if you're having dizziness. I now know to stop moving, lower my head, and hold onto something stationary. That was what led me to a chiropractor to begin with, that middle of the night fall. After a couple of treatments, I realized the migraines stopped. Back then, I was taking Imetrex, and it wasn't really helping me very well. I guess the fall was a good thing!
