Could be many things: There can be many causes, such as low blood pressure or variations in the blood pressure when one changes position from sitting to standing (orthostatic hypotension), or low pulse rate (bradycardia). If symptoms are bothersome enough and don't resolve with simple maneuvers such as hydration and standing up slowly, i would recommend a physical exam ad blood pressure/ pulse check by our doctor.
