I guess everything is relative. My standing blood pressure is usually 80/50, sitting is 90/55. Unless I'm in the doctor's office, then it's 180/85 and they're trying to give me blood pressure pills. I think in my case the problem is autonomic neuropathy, which was not caused by diabetes but was a result of an autoimmune attack that also caused diabetes. My A1C has not been over 5.4 for 5 years but the blood pressure anomalies have not changed. I think I've just adjusted to them, it's not very often I can't function, a couple of times when my BP has been 65/40 or something. Then I try to sit and have a couple of cups of coffee or tea until it's higher. When I worked I'd call in and tell them I needed to be a couple of hours late. Now that I'm retired it doesn't matter, I just stay in bed a while longer. The bottom line is, unless your blood sugar has been very, very high I doubt that's the cause.
