Vagal Nerve Problems: Yes, an exaggerate vagal nerve response can contribute to dizziness. Probably, this happens when the vagal nerve causes the heart rate to slow down. If this happens any more often than rarely, go see your doctor. You need to exclude irregular heart rate rate, fluctuation in blood pressure, and sudden rising or falling blood sugar - three reasons for dizziness around meals.
