Caffeine Diabetes And Insulin
A study examining the relationship between caffeine, insulin, and blood sugar found that diabetic people who consumed approximately the same amount of caffeine as you would get from drinking two cups of coffee had more variability in their blood sugar levels.
Specifically, the study broke diabetic subjects up into two groups, one taking two 250 milligram caffeine pills per day and the other a placebo. The caffeine pill group had 8% higher blood sugar levels than the placebo group on days when they did not take the caffeine pills.
The reason for this effect is how caffeine affects your bodys natural insulin sensitivity. Consuming caffeine kicks off a domino-like chain of chemical reactions in your body that ultimately means it doesnt process sugar as effectively. Caffeine intake raises epinephrine levels, and epinephrine reduces your bodys insulin production.
Caffeine also blocks adenosine, a molecule that helps regulate insulin production. In combination, these two effects mean that caffeine reduces your bodys ability to produce and regulate insulin levels, which indirectly raises blood sugar. If you only drink coffee occasionally, the ups and downs of insulin sensitivity on days you dont drink coffee causes blood sugar levels to fluctuate, making it difficult to monitor and treat diabetes.

The Short Term: Caffeine Reduces Insulin Sensitivity
Since coffee on its own doesnt contain carbohydrates, simply drinking a cup shouldnt raise glucose levels. To test its effect on glucose metabolism, researchers typically ask study participants to consume either caffeine or coffee with a meal or an oral glucose tolerance test and then monitor their insulin and glucose levels. What theyve found is that insulin and glucose levels tend to rise. That suggests that caffeine causes a decrease in insulin sensitivity since the elevated insulin isnt bringing down the glucose increase from the ingested carbs. In other words, caffeine seems to impair insulins effectiveness. Research has shown that insulin sensitivity drops in response to a single dose of caffeine following 72 hours of caffeine avoidance. It also drops after high coffee consumption over four weeks, suggesting the body does not build a tolerance to caffeines effect on insulin over time.
Research shows the same effects in people with Type 2 diabetes, but the impact may last longer given their existing metabolic impairment. One study at Duke University looked at how consuming the caffeine equivalent of about five cups of coffeehalf at breakfast, half at lunchimpacted participants glucose levels throughout the day. It found that caffeine raised their glucose responses to breakfast, lunch, and dinner, as well as causing an increase in their overall average glucose for the day.

Estrogen in birth control pills can affect the way a person with diabetes may respond to insulin. The American Diabetes Association advises women with diabetes to use a birth control pill containing norgestimate and a synthetic estrogen.

Women with diabetes should discuss their birth control options with their doctor.

What Is It About Coffee That Affects Blood Sugar
The majority of people with diabetes see a spike in their blood sugar when drinking coffee, and its not a mystery that a lot of the cause can be attributed to the caffeine content in your morning cup.
According to the Mayo Clinic, for people with diabetes, about 200 milligrams of caffeine can cause a spike. Caffeine causes insulin resistanceand can negatively affect postprandial blood sugar levels, essentially requiring you to take more insulin for foods eaten when you drink caffeinated beverages. Some people even need to bolus for drinking plain, unsweetened, black coffee that has no carbohydrates.
Ironically, long-term coffee consumption is associated with higher insulin sensitivity and lower rates of type 2 diabetes, but in the short term, the caffeine content causes a spike in blood sugars and lower insulin sensitivity. Caffeine is also an appetite suppressant, so its overall effect is sometimes balanced out.
The best option for people with diabetes who are struggling with blood sugar spikes post cup, however, may be to opt for decaf: drinking decaffeinated coffee seems to curb blood sugar spikes in individuals.

High Blood Pressure And Coffee
Now, let me say a word about coffee and people with high blood pressure. Should you drink coffee if you have high blood pressure?
Of course, you can drink coffee if you have high blood pressure. But you need to be careful.
When your blood pressure rises with coffee use, the effect is not responsive to high blood pressure medications. It is a sustained effect that is not easily reversed with high blood pressure pills.
Secondly, the effect of coffee or caffeine on people with high blood pressure is much more dramatic compared to people without high blood pressure .
So, whereas, you may have a rise of 6 mmHg systolic in someone without high blood pressure, you who has high blood pressure may experience a systolic rise of 12 mmHg or higher.
Now remember, I said earlier on that BP increase with coffee does last up to 3 hours. Imagine, if you are one of those people who drinks several cups of coffee a day.
Imagine a situation where youre constantly topping up your coffee fix when you are experiencing a caffeine crash every 4 hours or so. What do you think will happen?
Your elevated blood pressure reading will be sustained. Because whenever your blood pressure is beginning to settle, you spike it again with your top-up coffee.
Can you see how you can sabotage your blood pressure control efforts by your coffee drinking habits?
