Has anyone noticed a correlation between low blood pressure and high blood sugar? I’ve been outdoors all day for the past 4 days. It’s been very hot and for the past two days I’ve had low blood pressure. Last night (after a day full of walking around a festival) and not eating terribly (not great but nothing excessive) my blood sugar was 440. I couldn’t figure out why it would be so high but then it donned on me that maybe the low blood pressure had something to do with it.
