Assuming the two coffee's contained less than 15 carbs (the equivalent of about 4 sugars total or a total of 1/2 cup of milk/cream - think a "latte") then since you rose above 126 (7.0 mmols) on an otherwise empty stomach, that "would be" considered a spike

BUT too many variables to specifically point to the Coffee as the Culprit

What would your blood sugar have risen to if you didn't drink it?

Until we "break the fast" after sleeping there are a number of hormones that are still causing the Liver to handle our sugar needs

And we are all "metabolically" a little different

To "sorta/kinda Know" if the coffee is what effected you, you would have to do your own unscientific/unblinded mini study

For a few days/week wake up and eat/drink nothing for the first hour or two and see what your sugar levels do

Then compare in the second week where you wake up and have your 2 coffee's to get kick started

You could find that the coffee has great effect "in comparison", does "nothing at all" or may even prevent your BG from climbing higher than it would have

T2 is metabolic and there is just so many variables that we need to be careful when we point a finger based on a single observation

But again to your base question - yes, over 126/7.0 "without" eating enough carbs to break the fasting cycle would be considered a "spike" - not even close to dangerous at 135, but certainly not something that "should" happen if everything internally was working properly

I'm 76 ,still drink coffee.Only time I stopped was in renal ward of specialist hospital last October when the staff refused to serve coffee " because it harms kidneys" but eventually I got my coffee!!!!!!

Hi Jimmers...a very good question. I'm going to research it. I research the same thing about coffee, but for chronic kidney disease and its ok to drink coffee. It's up to the person drinking coffee or tea...swettener or sugar; well both are bad but swettener is worst. Have a blessed day.

Thank you Graham and Pandapat for your answers to my question. The reason that I asked the question was that talking to fellow type II people we got into a discussion about coffee and I wasn’t certain if my one or two cups daily was affecting me. My A1C for the past three years has been under six. I am 75 years old.

Depends on the range you're using If standard range 4-10/72-180.then your level after coffee is not a spike( higher than your top of range).If your top range level is 7.8/134( like @A DiabetesTeam Member) then you have just about gone over the top.
As Graham says- many variables....me- I'd drink the coffee and not worry.
