Hi
@copey399 yes, I get these same symptoms occasionally plus blurred vision, usually when my blood levels have been showing marked rises and drops for a couple of days ( owing to me eating higher carb than usual) it doesn't usually last for long once I resume eating properly. The dizziness and photophobia for me was caused by low blood pressure- often after exercise and was easily fixed by stopping my meds. Maybe you need a general medication review ? especially since you've lost a lot of weight and the dosage of pain meds etc may need to be adjusted. As you know, dizziness can be caused by high blood sugar too, anyway, good luck with it all. Take care
