Does Caffeine Affect Blood Sugars?

It goes without saying that we’re talking about caffeine alone and not a caffeine infused hot fudge Sunday or Red Bull, which obviously have tons of calories. Caffeine does not have any calories, however it can raise the blood sugar levels through a complicated biochemistry pathway which I won’t talk about here because it would put you to sleep.

It is very important to note that caffeine affects everyone differently. In sensitive folks, too much caffeine can cause their heart rate and blood pressure to go up and cause insomnia. Others are resistant to these potential effects of caffeine, and they can drink 3 pots of coffee a day without symptoms.

Up to 400 milligrams per day should not have any noticeable effects on most people. Two 8 ounce cups of black coffee have approximately 280 milligrams of caffeine. If you love coffee like I do, you should not stop unless your health care provider has some other medical reasons why you should limit your intake.  Caffeine intake is like many things in our life, use with moderation and your symptoms should dictate how much caffeine you should have per day. If you’re concerned about how it may be affecting your blood sugars, you can remove it from your diet for a couple of weeks and see if you notice a difference. For now I am going to finish my hot fudge sundae!

    I have heard that diabetics with Type 1 Diabetes and on ACE inhibitors are at higher risk for the COVID-19 virus due to the ACE receptors in the lungs. Do you know anything about this? Are we at higher risk due to being on ACE inhibitors? Thank you!

    • This statement is absolutely not true and not substantiated. DO NOT STOP YOUR ACE INHIBITOR unless your HCP tells you to. Be careful of misinformation.
