I've recently read many comments on this site about caffeine rasing BS levels. I've never heard that before and I've had Type 1 for 27 years. Is it a Type 2 thing? Where does it come from? How much do you have to take before it shows an effect? and how much of an effect?

I've never experienced it before and was just curious how / where this came from?

I'm type 2 and extremely sensative to caffeine. I was even before I became a diabetic. But, I started noticing that when I would have a cup of regular coffee or drink a diet soda with caffeine my sugar would go up. I thought it was just a weird quirk with me but then did some research and there are some folks who are diabetic and caffeine causes a rise in blood sugar. If there is some wird thing gonna happen it will be

I too would like to know. I was a nurse for many years and never heard it. I tried stopping caffeine to see it it made a difference and found none. I only drink soda, maybe its a coffee tea thing. Maybe bothers some folks and not others. Like some diabetics cannot eat white potatoes and others like me eat them in moderation without much problem at all…just cut out bread. Would like a good scientific exlaination for the claim…thanks for posting.

Im T1 and caffeinated coffee really spikes me to the point that I just quit drinking it. Soda and tea cause a minimal rise in my blood sugar.

I drink Coffee daily. It does not affect my blood sugars. Neither does tea or soda. I do know that Green tea lowers blood sugars and cholesterol. My A1C use to be11. It dropped to 8. My cholesterol use to be 134. It is now 90. I was not on any cholesterol lowering diet. I just drank the green tea, and my cholesterol and A1C went down. I did go on a diet after my cholesterol went down to 90. I lost 24 pounds. I went on a low fat high fiber diet. I eat low fat meat. I cut back on regular cheese. I use low fat mozzarella made with skim milk. I use 1% milk. I eat oatmeal, and high fiber cereals like all bran, bran flakes,and shredded wheat. I eat 100% whole wheat products like stone ground whole wheat bread, and flat bread. 100% whole wheat bagel thins, sandwhich thins and muffins. I eat 100% whole wheat crackers for snacks such as special K crackers and lots of fruits. I make sure the ingredients in the crackers is whole wheat flour. I do walking exercises and burn at least 300 to 500 calories a day, and I started doing yoga. It

I am wondering if you like myself use a flavored creamer. That might be something that gives a spike. Some of the liquid and powder creamers have 5-7g of sugar per serving and one serving per cup is just not enough for bold flavored coffees. Maybe you like myself need to go to a milder blend of coffee so one serving is enough. Also they do have a half caf. coffee now that is very nice. This is a good coffee if you have slightly elivated b/p also. The half caf gives you that good coffee flavor from reg coffee without the decaf coffee taste.

I'm still unclear as to the science behind this. Is there something else in your coffee? High sugar flavored cream maybe?

There is the argument that caffeine can cause dehydration (which can raise BS levels slighty) - but you'd have to have a significant amount before you would notice even a small change.

Did the spikes go away when you stopped your coffee? Did you change anything else - diet / exercise? Thanks for responding.

No its plain black coffee, absolutely nothing else in it! I would have mentioned that, if that were the case. No one knows why some of us experience a spike and others dont. A couple of schools of thought are that caffeine directly affects the insulin molecule, making it work slower. Another is that it can impact levels of adrenalin and cortisol which in turn can stimulate the release of glucose from the liver. We are all different so what happens to me may not be the case for you, but for me, the more caffeine I ingest, the more I spike. And it took me awhile to catch on to this phenomenon cause it really doesnt make sense, does it?

Dealing with morning spikes after I get up and test, I thought it was my coffee. So one morning, just had water. BS spiked anyway. And the mornings I drink it, it spikes the same amount. So I think it just depends on who you are as different things bother different people.

Interesting. Thanks for sharing. I applaud your efforts to test how/why you get the reaction you've gotten in the mornings. I typically have a caffeine pill (1/2 of one) when I get up since I exercise at 4:30 am everyday and I don't drink coffee. On the days I don't workout and I skip the pill - I really don't notice any sugar level changes.

Hi. I've never myself expirenced that. Its possiable but in my expirence it has not raised my blood sugar personally. Hopefully someone else knows about this and can answer better. I would think caffine being a stimulant speeds up a metablisim and would almost have the oppisite effect but I do not know. I do know caffine has NEVER bothered my blood sugar personally…I will follow this post because I'm curious as to what the answer will be. Sorry I couldn't help..
