I have a suggestion. Bear in mind I’m not someone with Diabetes, but how about instead of telling them or asking them, because it makes it seem having this illness is a chesoron and you’re asking permission, you make a comment- “Oh I have to go inject myself with insulin now” (even if you use the pump), or “You know, I try to stay away from candy, cakes, whatever (if you do), because I have to watch my blood sugar- so the next time I take it, it shouldn’t be too high”.
