No: Sounds like you are may be pushing yourself too hard. Be sure to be checked by your primary care physican before embarking on an exercise program to rule out heart or other problems. The dizziness and temporary vision loss usually means your brain isn't receiving enough blood - best to find out why!

This is not normal : But certainly could be attributed to dehydration and electrolyte imbalance. Any eye cause would have to be ruled out by examination.

A 47-year-old member asked:

Does having a slow heart beat cause dizziness?

Poor blood flow: The balance centers of the brain depend on good blood flow to the brain. If the heart is beating slowly or is not pumping enough blood into the brain, you will feel dizzy. First is to lie down so that the blood flow does not have to go uphill. Next is to lift the legs to be sure enough blood is getting into the heart. If the brain does not get enough blood flow, you can pass out and fall.

Can be other causes: Dizziness with exercise doesn't just happen with inadequate hydration. If a person is well hydrated, and still gets dizzy, her doctor can evaluate. Sometimes there are circulation problems, such as not enough blood flow to the brain under certain conditions or activities. There can be heart problems, or not enough red blood cells (anemia), etc...
