Others have discussed this medical issue on the forum, who also have diabetes and have been vaping for around a year just fine. Some think it is the nicotine level that can also be a factor (so is smoking), not the PG or VG. Here are a few threads for you to read:

My husband (non vapor/smoker) struggles with his blood sugars... He was fine until last year, and now he's pre-diabetic. It is frustrating. Targeting the things that spike sugars is hard sometimes. We did some research and discovered that he was taking too much fish oil and had an odd reaction to it (we think, it reacts differently with some people impairing sugar control). Flour, caffeine, processed foods and alcohol also play havoc with blood sugar. He's bad about limiting those (well, not the alcohol, but he still has a beer once in a while). He's still trying to manage it a year later with diet and a prescription. He cheats on the diet, LOL. Bottom line is getting older sucks and having to study and understand how food is metabolized isn't his thing, but he's getting better at making choices.
Good luck to ya!
