inactivity cause dizziness?

I don't think the lack of excercise would be the cause.  I do think that a body that is in good physical fitness probably is able to cope better with certain underlying conditions.  So maybe a fit body wouldn't show symptoms of an underlying condition.

Definatley see your doctor and discuss all your symptoms with him/her.  I'm no expert but a good place to start researching would be hypotension, postural or orthostatic.  Get your blood pressure checked and talk to your doctor about those symptoms.  If your doctor also suspects hypotension then a tilt table test would be used to confirm the condition.

Again, I'm no expert so make an appointment and see your doctor.
