What causes a person to get dizzy spells during exercise ?

I had a stress test and passed in November, my BP when checked on Aug. 16 was 164/90. My doctor recommended either 1 hour exercise of walking or equivalent 5 days per week, or go on meds. I chose the exercise, and I found that I get dizzy after about 1/2 hour, and when mowing grass behind a push mower, I get dizzy and started to get nausea. These things went away after I rested. Can high blood pressure alone cause this or is there other factors?

High bp can cause the symptoms you're describing, but an underlying heart condition can also. Ask your doctor to do an EKG if he hasn't already. http://www.webmd.com/heart-disease/Exercise-Electrocardiogram
