How Drinking Coffee First Thing After Night Of Poor Sleep Impacts Blood Sugar
Physiologists at Bath examined 29 men and women after each of them experienced three distinctly different nights of sleep. In one experiment, the participants enjoyed a normal night of rest. This was followed by a sugary drink which roughly equals the calories eaten during breakfast.
During the next two experiments, each volunteer was woken up every hour throughout the night to create a disrupted sleep. In one instance, the participants were given the same sugary drink after waking up. After the other bad sleep, researchers gave the group a strong black coffee 30 minutes before having their sugar. A blood test was then taken following each night of sleep and the drinks each person consumed.
The results show that one good or bad night of sleep makes little difference in a persons blood sugar/insulin responses. Researchers note that previous studies link several nights of insomnia to metabolic issues, but add a single incident where you cant fall asleep doesnt carry the same weight.
When coffee enters the picture, thats when the body sees a drastic change. Study authors report participants drinking coffee right after a bad night of sleep increased the blood glucose response to breakfast by around 50 percent.
We know that nearly half of us will wake in the morning and, before doing anything else, drink coffee intuitively the more tired we feel, the stronger the coffee, Prof. Betts explains.
Coffee Before Breakfast Increased Blood Sugar Levels By 50 Per Cent
Past research suggests that losing many hours of sleep over one and/or multiple nights can have negative metabolic effects, so it is reassuring to learn that a single night of fragmented sleep does not have the same effect. However, strong black coffee consumed before breakfast substantially increased the blood glucose response to breakfast by around 50 per cent. This new study reveals that the common remedy of drinking coffee after a bad nights sleep may solve the problem of feeling sleepy but could create another by limiting your bodys ability to tolerate the sugar in your breakfast.

So What Are My Options
I would suggest switching to coffee or green tea because some studies have shown that they can actually help improve your blood sugar levels.
But if you just cant seem to live without your daily caffeine fix, you should definitely consider what my private clients have done.
First, dont drink your calories.

What About The Glycemic Index
The glycemic index of foods is a rating of how individual foods raise blood sugar. The daily carbohydrate total is one way to manage blood glucose levels. Consequently, eating beans and whole grains that have a lower glycemic index than white bread or pasta can help keep blood sugars lower. So, if you want a small amount of high glycemic index foods , it would be better to have the rest of the daily carbohydrate total made from low glycemic index foods. The ADA has glycemic index ratings and offers diet suggestions for people with diabetes.

Drink Decaffeinated Coffee Instead
If you have diabetes, just having about 200 milligrams of caffeine can affect your blood sugar. This is the amount of caffeine you get in about one or two cups of brewed coffee or three or four cups of black tea. This means black coffee is a better option for people with diabetes.
However, different people may react to it differently, depending on certain factors like age, weight and how much caffeine one usually takes.
If you have diabetes but can’t do without a cup of coffee in the morning, experts suggest drinking . This will help you get the benefits of other compounds in coffee such as magnesium, chromium and polyphenols without affecting insulin sensitivity.
Some studies suggest that the antioxidants in coffee can help reduce inflammation in your system and lower your odds of getting type 2 diabetes in the first place.

Surprising Things That Can Spike Your Blood Sugar
When you first found out you had diabetes, you tested your blood sugar often to understand how food, activity, stress, and illness could affect your blood sugar levels. By now, youve got it figured out for the most part. But thenbam! Something makes your blood sugar zoom up. You try to adjust it with food or activity or insulin, and it dips really low. Youre on a rollercoaster no one with diabetes wants to ride.
Do you know all of these blood sugar triggers?
Knowledge is power! Look out for these surprising triggers that can send your blood sugar soaring:
Common Types Of Coffee And Your Blood Glucose
There are many types of coffee, and so, caffeine content can vary. But let’s start with a simple baseline. The average American will drink two cups of coffee per day, which is around 280 milligrams of caffeine in total. And the way your body responds can depend not just on the amount, but also on what type of coffee you’re drinking. Here’s a little more information about the different types and variations of America’s favorite beverage.

Coffee And Diabetes: How Coffee Affect Blood Sugar
Ah, that alluring smell of newly brewed coffee can make any coffee drinker yearn for a cup! But have you also noticed that sometimes , your coffee and diabetes doesnt seem to agree?
You might see your blood sugar shoot up after that first cup of coffee in the morning or maybe you find that you need extra insulin for your meal when you have a coffee on the side. And maybe thats making you question should or can people with diabetes have coffee?
In this post, I will explain everything you need to know about caffeinated beverages: How it impacts blood sugar, its effect on insulin sensitivity, and if coffee is good for people with diabetes.
Caffeine And Insulin Resistance
A study consisting of 10 people with type 2 diabetes set out to determine the impact of regular caffeine consumption on overall insulin levels.
All participants were regular coffee drinkers, consuming about 4 cups of coffee per day, but they all stopped drinking coffee during the study. Then half of them were given capsules containing 250 mg of caffeine, and the other half were given placebo pills containing zero caffeine.
The result, according to the study: On the days the patients took caffeine, their bloodsugar levels were 8% higher. And after every meal including dinner their blood sugar spiked higher than it did on the day they had no caffeine.
Does this mean people with diabetes shouldnt drink coffee and other caffeinated beverages? Not necessarily. It means we should look closely at our caffeine consumption and moderate it just like we would with other things that impact our blood sugar levels.
Just because black coffee and green tea contain zero calories doesnt mean we should drink them without limits. Instead, caffeine should ideally be something we consume carefully and set personal limits around for the sake of our overall diabetes health.

Does Caffeine Raise Your Blood Sugar
For a normal and healthy human being, drinking caffeine doesnt have any notable change on the levels of blood sugar.If you try an experiment of constantly monitoring your blood sugar level while maintaining your daily consumption of caffeine, you will find very slight or no change at all.
However, for those people who have diabetes especially type 2 diabetes, drinking caffeine may have an impact on your blood sugar.
This is because it has been found to be very effective when it comes to raising your blood sugar levels substantially.
Some research indicates that for caffeine to affect a healthy adult, he or she should take a considerably high amount of caffeine.
This, however, doesnt mean that it will have an impact on everyone who does that.
There are some people who will just feel fine even if they take a high dose of caffeine in their coffee.
What this indicates is that different people require different amounts of caffeine intake before their blood sugar levels spike.
You should, however, ensure that you gauge the amount of caffeine you intake on a daily basis to prevent any sudden shifts in your blood sugar.
Patients with diabetes should always be monitored in this case.
What About The Caffeine In Coffee
Thereâs another twist to the story. Studies show that coffee may lower your odds of getting type 2 diabetes in the first place. Experts think thatâs because the drink is high in antioxidants. These compounds reduce inflammation in your system, which can raise your chance of having the disease.
If you already have type 2 diabetes, this may not hold true. The caffeine in a cup of java makes it tougher to control your blood sugar. If yours spikes after your morning cup, you may want to switch to decaf. Even though this drink has a tiny amount of caffeine, it doesnât have the same effect on your blood sugar or insulin.

Coffee Does Not Seem To Raise My Blood
The graphs below show my blood-glucose levels over a 4-hour period for three separate experiments. The blue line is the blood glucose on a morning I drank coffee. The red line is on a morning without coffee.
Experiment one
The first experiment indicated that coffee may raise my blood sugar. But only slightly:
The graph above could suggest that drinking coffee prevents my blood-sugar levels from dropping to the same levels as the morning when I didnt drink coffee.
Experiment two
The second experiment indicates that coffee does NOT noticeably raise my blood sugar. Theres a lot of variety in my blood-glucose levels on these two days, but to us it seems that coffee does not raise my blood sugar relative to not drinking coffee .
Experiment three
The third experiment also suggests that coffee does not raise my blood sugar much. My blood-sugar levels are quite flat, both on the morning when I drank coffee and the morning I didnt, indicating that the coffee didnt impact my blood-sugar levels much.

How Coffee Affects Blood Glucose Levels
If you’re an avid coffee drinker, chances are you’ve thought about whether that morning cup has any effect on your blood glucose levels. If so, you’re not alone. Some studies show that drinking coffee might cause some people to experience blood glucose spikes or crashes. Still, the effects of caffeine on your blood sugar are a little more complex than that.
If you want to understand what happens to your blood sugar when you drink coffee, it’s crucial to know all of the factors that come into play when youâre drinking it. Even with all the information weâre about to give you, remember that everyone has different responses to different food and drink. To track how your body responds to coffee in real-time, consider getting yourself a continuous glucose monitor!
Research Design And Methods
The studies were approved by the TNO Nutrition and Food Research Medical Ethics Committee, and all participants gave informed consent. The trials were originally designed to study the effects of coffee and caffeine on plasma concentrations of homocysteine, and the study designs have been reported in detail previously . Participants were regular coffee consumers and did not have known diabetes.
In study 1, treatment responses were compared using paired t tests. In study 2, we tested for overall treatment effects using ANOVA. All reported P values were two sided, and P values < 0.05 were considered statistically significant.

Cutting Coffee Could Help Control Diabetes
New research suggests that daily consumption of caffeine in coffee, tea or soft drinks increases blood sugar levels for people with Type 2 diabetes and could undermine efforts to control the condition.
Researchers at the Duke University Medical Center in North Carolina, USA, monitored the glucose levels of ten people with diabetes, who drank at least two cups of coffee a day and who were trying to manage their condition through diet, exercise and oral medication.
They were monitored for 72 hours and the study found that when they consumed caffeine their glucose levels went up by 8 per cent.
Caffeine And Blood Sugar Levels
Regular high caffeine consumptio, over a 4 week period, has been shown to impair insulin sensitivity in people with type 2 diabetes.
Whilst the researchers found a relationship between higher coffee consumption and lower sensitivity to insulin, they recognised that the rapid transition to having more coffee may have produced an atypical or emphasised response by the body.

Caffeine Raises Blood Sugar In Patients With Type 2 Diabetes
US Pharm. 2008 33:HS-16. Researchers at Duke University have discovered that caffeine taken in even moderate doses could impair glucose control in patients with type 2 diabetes. According to James D. Lane, PhD, of Duke University, a small study showed that when patients with type 2 diabetes drank the equivalent of four cups of coffee a day, their blood glucose levels were 8% higher on average. His results were published in Diabetes Care. Dr. Lane suggests that patients with type 2 diabetes cut coffee out of their diet to see if this better controls their blood sugar levels. “Caffeine is so widely consumed in our society that we tend to forget or ignore the fact that it is a drug that does have widespread effects in the body,” said Dr. Lane. Dr. Lane and his colleagues hypothesize that the caffeine may affect blood glucose in patients with type 2 diabetes in two ways. The first theory is that caffeine impairs the transport of glucose out of the bloodstream and into the cell. A second theory is that, because it promotes the release of adrenaline, caffeine stimulates the liver to continue to release glucose even after a meal. To comment on this article, contact .
Coffee And Diabetes Prevention
According to research done and facts gathered it is appropriate to say that caffeine doesnt have any significant impact on a healthy adult even if he or she takes as much as 400miligrams of coffee.
This limit, however, is different from one adult to another. But for those people with diabetes, it is would be safe to ensure that they take the least amount of coffee or better yet avoid coffee altogether.
So that they dont end up altering their insulin levels which may lead to the spiking of their blood sugar level something that is much more dangerous when you have diabetes, or you are prediabetes.
If you are a coffee lover and you are diabetic at the same time, it would be much better to seek a doctors guidance on the amount of coffee that is appropriate for your health.

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.
