Not sure about this exactly, but from a pharmacological and physiological perspective it may have something to do with the fact that PG is used to treat Ketosis Lypolosis in livestock. That's not the same thing, mind you, as diabetic-ketoacidosis. Ketosis results in your brain sort of chopping up fat cells and going through a few different changes to utilize ketones as fuel. Now one might be inclined to think that if PG prevents or reverses this in animals it would also do it for us. If so, one might hypothesize, it could make it difficult for your body to use fat as energy and more inclined to use the glucose floating in your blood, which as you probably know should lower your serum-glucose levels. However, nicotine, a CNS stimulant, along with caffeine and other "uppers" has been observed to cause spikes in serum-glucose.
I'm new to
vaping myself, but I know that since I've quit smoking analogs I'm nearly chain-vaping. I am assuming and hoping that this will taper naturally as I've read many others have experienced. What strength of nicotine are you using? Perhaps try a lower strength for a day or two and test your sugar to see if there is a difference. Or alternate carts 0mg strength with whatever you're using now. This is of course only speculation and not intended to replace or supplement the advice of your Physician... just some thoughts. Also, of course I'm sure you've heard more times than you care to recount, exercise lowers blood-sugar too.
