I've noticed that if I drink coffee in the morning, I will get a low b.g.

It doesn't matter what type of coffee, it can be anything…even a blended coffee beverage.

I don't think it has to do with the caffeine because I don't experience the lows when I have a diet coke (caffeinated) in the morning.

I eat the same thing with the same amount of insulin every morning..I'm usually 85-95 after, but I go as low as 65-75 with coffee!

I had that problem for a long long long time—-I would drink black coffee in the morning, and I'd go low every time—-very very low—-down to 83, 79—-for me anything below 140 is low—-I can handle 100, but any lower than 100, I get shaky. I cured my problem—-you won't like this, but I use creamer and a little bit of sugar with my coffee, and not only do I NEVER go low anymore, I have raised WAY up—-the doctors and nurses won't like this, but I sure as heck feel a LOT better—-it's going the opposite now—too high, so, I have been working on stabilizing it down, but not too far down. I found out it was the ACID in the coffee that set me too low—it's too hard on the belly, and the acid burns off sugar at a super high rate—-that's if it is pure strong BLACK coffee—-I bet it's the acid that is doing it to you, too—-I could be wrong, but that's what happened to me. As far as caffiene goes—I have 2 cups of it a day, and it HELPS me a LOT—-however, if I go over 2 cups, I am in big trouble, it then does the OPPOSITE—it hurts me really really bad—-gives me the shakes, panic attacks…so, I never drink more than 2 cups a day anymore. What's AMAZING is if I drink under 2 cups, I cannot FUNCTION——ha, ha…amazing stuff…ANNE

Well that just shows how unique each of our metabolisms are Lindsey. If I drink a coffee I will have a rise in my glucose readings. Due to my kidney problems I drink water almost exclusively. I guess that means you ought not have more than one cup of coffee in the morning.

i read a study that just came out that says coffee lowers blood sugar so diabetics drink up. it said the more the better. I have been forcing myself to drink at least 3 cups a day ( I am a tea drinking). I found one I like it is dunkin donuts cinnimon. The study says it is just coffee, not tea or pop. who knows just watch your levels don't go down too much. Can't wait till next week when there is a new study out.

It definitely is true—-I have lowered my blood sugars a LOT with coffee—however, the downfall for me ( I have a borderline high metabolism) is that if I drink too much of it, I go WAY way way too low, then I get the shakes, then my diabetes goes WAY out of whack. I used to drink 6 cups a day of strong black coffee, and it was bad for me—-too much. I drink 2 cups a day now, and have never felt better—-I honestly believe and know coffee is a VERY beneficial drink—-ANNE

Glad you have that balance now. We are all so different aren't we? Coffee sends mine up, not much, but up.
