Black Coffee

Hi

When drinking black coffee my BG raises by at least 1.5 mmol, does this happen to anyone else

Hi Caroline

Are you drinking the black coffee on an empty stomach?

Sarah

Hi Sarah

Yes, a lot of the time. Does that make a difference?

Hi Sarah

I think your right, it's just one of those things. Thank you anyway

I drink 20-30 mugs of black coffee a day, and has no effect on my BG. I did notice that waking and having a couple of mugs before checking my BG and having breakfast, my BG was elevated; I put that down to waking hormones working before I’d taken on the insulin as there was no other event in the preceding day or overnight. If I have the coffee with breakfast (or any time during the day), its just the other carbs and insulin doing their thing.

It might be worth trying coffee after a fasting lunch, and see what happens during the course of the afternoon. I’m no medical practitioner, but maybe its stimulating some hormone release that raises BG (like a stress response), but that should resolve itself when your liver takes back any glucose it released. Just a possible theory, with no clinical basis!

Thank you NottsKnots for your reply, I might just try the fasting lunch just for interest. There is no reason why black coffee should raise my BG and it doesn't always happen
