I tried to figure out why I get what seem like hyper when I drink coffee. The effect doesn’t last long; maybe 15 minutes. As a test I did a fasting reading first on a morning of 4.7 then 15 minute after drinking a coffee (no sugar) got reading of 5.6 which doesn’t sound a lot and is still in 4-7 mmol range but I suspect it’s the rate of change that gives me a hyper symptom.

What are your experiences of coffee or any other drink with caffeine?

Hi RMZ, beautiful duck photo !
I feel a bit buzzy after the first cuppa of the day. I think it is the caffeine that does it.
Also caffeine is known to stimulate some release of sugar stored up the liver. When having a cappuccino at home ( I am in learner mode there) or out at a cafe I allow about 25 g of carbs for the coffee, milk, caffeine etc and bolus in the insulin from the calculation my insulin pump makes.

See what happens if you do everything the same without the coffee. It could very well be that your bg acts the same and the rise has nothing to do with the coffee but is just your liver dumping glucose in your bloodstream because you got out of bed.
 
Caffeine is a di-phospho-esterase inihibitor that increases the cellular levels of cyclic-AMP ( big ON signal ).

Think of an adrenaline boost as turning on the tap - and caffeine as blocking the plug-hole.

The hyper symptoms may well be a response to the Caffeine.
 
I drink quite a lot of coffee but can't say there is any significant affect on my sugar levels.. Maybe accept when I have a flat white..
 
Caffeine stimulates release of cortisol, which will produce a rise in BG due to release of liver glycogen. Stress response.
Could also be liver dumping Its not a massive rise, either, 1 mmol? An off the wall question....did you test each time with the same meter? Different meter may have variation of +/- 20%.
 

Try decaffeinbated coffee!
