Should I be worried? I've recently (the last 6 months) found that when my blood sugars reach 200+, usually in the mornings, and my blood pressure drops to 95 over 55. My blood pressure is normally 120 over 70. When my blood pressure drops I feel terrible: no energy; hard to breathe; light headedness; piercing pain in my forehead, which only happens when standing or walking and immediately subsides if I bend down. I'm a 47 yr old type 1 diabetic. I've had diabetes since the age of 7.
I would not say that you should be worried, but you should have these symptoms evaluated by your doctor. You mention that the symptoms come on when your blood glucose is high. Hyperglycemia can cause dehydration. Dehydration can cause a drop in blood pressure when standing. This is called orthostatic hypotension. Orthostatic hypotension may also be caused by diabetic neuropathy. It is important to determine the cause of your symptoms so that cause can be addressed and you can start feeling better.
