Why Does Caffeine Cause Blood Sugar Spikes

Does Caffeine Raise Blood Sugar? – by Dr Sam Robbins

Caffeine spikes blood sugars in a number of ways, including:

  • Naturally raising levels of certain stress hormones, epinephrine, and adrenaline, making you more insulin resistant when you drink it
  • Blocking the protein adenosine, tamping down the amount of insulin your body produces , making it more difficult for the body to process carbohydrates as quickly, spiking your blood sugar levels.
  • Inhibiting sleep, when consumed later on in the day. Lack of sleep for even a few days has proven to lower insulin sensitivity and increase insulin resistance, keeping blood sugars stubbornly high

And it isnt only the caffeine found in coffee affecting blood sugars. A 2004 study showed that taking a caffeine pill before eating resulted in higher post-meal blood sugars and insulin resistance for people with type 2 diabetes. The same can be inferred for caffeinated sodas, chocolate, tea, energy drinks, and even protein bars.

Upswing: Steroids And Water Pills

Steroids, commonly used to treat rashes, arthritis, asthma, and other medical conditions, can cause blood sugar levels to rise. Corticosteroids such as prednisone may trigger the development of diabetes in people with a tendency toward diabetes. Diuretics may raise blood sugar levels, while antidepressants may either raise or lower them. If you need to take these medications and have diabetes, carefully monitor your blood glucose levels to see how these medications affect you.

The Long Term: Drinking Coffee Lowers Type 2 Diabetes Risk

If caffeines negative short-term effect on glucose metabolism is well established, so is coffees desirable impact on the risk of Type 2 diabetes. That coffee lowers ones risk of developing diabetes has been confirmed in multiplereviews, as well as in large population studies.

One study, which followed nearly 1900 adult men and women for a median duration of 5.8 years, found that adults who consumed at least one cup of coffee per week had a 22% lower risk for prediabetes and 34% risk reduction for Type 2 diabetes compared to people who didnt drink coffee. Another study, which followed around 88,000 women in the US with no history of diabetes, found that both regular and decaf coffee consumption for eight years seemed to lower the risk of developing Type 2 diabetes, with regular coffee offering a slight edge over decaf. Drinking more cups was associated with lower riskwomen who drank one cup per day saw a 13% reduction in relative risk, while women who drank four or more cups saw a 47% reduction.

That decaf demonstrates nearly the same benefits as regular coffee suggests that something other than caffeine is driving the protective effect. The most likely candidate is chlorogenic acids, members of a group of antioxidant-rich micronutrients called polyphenols, abundant in plant-based foods.

Chlorogenic acids may improve glucose metabolism in several ways, according to studies in animals and cell lines:

Important Conclusion On The Effect Of Coffee On Diabetics

An important study initiated by the Harvard School of Public Health has shown that people who drink one cup of coffee per day have an 11-per cent less chance of having type 2 diabetics. At the same time, people who have decreased the consumption of coffee to one cup have an increased chance of developing type 2 diabetics by 17-per cent. Out of the 1109272 people subjected to the study, 45335 had diabetes. However, with the end of the study, which included participants from 20-years to 10-months, the conclusion was that caffeinated and decaffeinated coffee lowered the risk of type2 diabetics. However, there is one thing you should know, coffee has a negative effect on an overweight person.

Caffeine Blood Sugar And Insulin

Does Drinking Black Coffee Raise Your Blood Pressure ...

One research study exhibited that consumption of a caffeine capsule prior to consuming food resulted in greater levels of post-meal sugar in type 2 diabetic patients. It also demonstrated an upsurge in insulin resistance. As per a recent research study, a genetic supporter might be involved. Genes might play a key role in the metabolism of caffeine and how it influences blood glucose. In this study, people who metabolized caffeine at a slow speed depicted greater blood glucose levels in comparison to people who genetically metabolized caffeine at a fast rate.

Certainly, theres a lot more in coffee excluding caffeine. These other things might be whats accountable for the defensive effect seen in the research study. Intake of caffeinated coffee over a long-time duration might also alter its effect on insulin and glucose sensitivity. Tolerance from chronic intake might be what causes the defensive effect. Another study demonstrated that chronic effects of coffee and caffeine might be associated with reduced risk of prediabetes as well as diabetes.

Caffeine And Glucose Metabolism

Hypoglycemia is a common side effect of caffeine, according to Drugs.com. However, the mechanism responsible is poorly understood. Researchers found that caffeine impairs glucose sensitivity in a dose-dependent manner, starting at a very low dose, according to a study found in the February 2013 issue of “Applied Physiology, Nutrition and Metabolism.” In the study, caffeine caused impaired glucose metabolism in healthy men and women. This data suggests that those with diabetes are not the only ones at risk for this side effect.

Typical Intake Of Black Coffee

Theres a clear variance in how diabetic people and non-diabetic people react to coffee and caffeine. A recent study consumed typical coffee drinkers with type 2 diabetes constantly monitor their blood glucose while performing every day activities. Throughout the day, it was found that right after they consumed black coffee, their level of blood glucose would ascend. Blood glucose was seen to be greater on days that they took coffee as compared to on days they didnt.

Why Caffeine Exerts These Effects

Studies think caffeine affects a persons insulin and blood glucose levels in the following ways:

  • Caffeine increases the levels of various stress hormones, such as epinephrine . Epinephrine helps in preventing the body cells from processing as much glucose. Also, it might keep a persons body from producing as much insulin.
  • It inhibits a protein named adenosine. This protein plays a huge role in how much insulin a persons body produces. Moreover, it helps in regulating how the body cells react to it. Caffeine keeps adenosine which is responsible for producing insulin in a persons body.
  • It takes a toll on the sleep patterns. An excess of caffeine keeps a person awake. Lack of sleep might reduce his or her insulin sensitivity.

The Diabetes Coffee Effect

Black Coffee Blood Sugar Response

Maybe its a symptom of my longtime type 1, but Ive never enjoyed polluting my coffee with cream, milk, sugar, or artificial sweetener. Uck no, thanks! Im a guy who likes his coffee black, which is fortunate in that Im not tempted to add anything in my coffee that may boost my blood sugars unnecessarily.

A few years ago when I was going through a diligent diabetes monitoring phase, I wondered about coffee. So I paid a bit more attention and noticed that it seemed to raising my blood sugars some in the morning hours. But that may have been caused also by Dawn Phenomenon, making my glucose numbers rise anyhow, and/or by inaccurate carb-counting the night before.

Doing some basal testing, it eventually became clear that my sugars were rising on a typical day, which always included mass coffee consumption. I wasnt sure if caffeine was causing the problem, but decided to increase my basal rates by about 50% for two or three hours in the mornings, and got to the point where I could maintain a flat line if all else was in line . There were also times Id take a a couple extra units and spread them out over a few hours, and that also seemed to work.

But what if I wasnt using my insulin pump?

During one of my insulin pump hiatuses was actually the first time I noticed my blood sugars were definitely going up more when I consumed black coffee but didnt compensate with insulin. A couple of units of insulin mid-morning would usually do the trick.

What Exactly Is Diabetes

With diabetes, your body is either not producing enough insulin or not using it efficiently . Insulin is a hormone that is normally released by your pancreas to help you take the sugar you eat and move it into your cells where its converted into energy.

If you cant make insulin or your body cant use it, your cells wont be able to absorb sugarand it builds up in your blood instead. This can lead to hallmark symptoms of diabetes like excessive thirst and urination, tiredness, and dizziness. Diabetes can also increase your risk for serious complications like kidney disease, vision loss, nerve damage, and heart disease.

What Are You Adding To Your Coffee

Even though those flavored creamers are a mere tablespoon of liquid, they are very high in sugar. Enough sugar to definitely cause an even larger spike in your blood sugar.

One of the most useful things you could do for yourself as a coffee drinker with diabetes is to gradually adjust your tastebuds to appreciate the taste of black coffee.

Try removing the sweetener and milk from your coffee for two weeks. Just two weeks! And see how you start to like the taste of black coffee! You might be surprised to find that you eventually find sweetened coffee to taste overwhelmingly sweet.

Other Factors That Contribute To Higher Blood Sugars

The caffeine content in coffee is not the only thing to blame for higher blood sugar levels, however. Many people prefer coffee first thing in the morning, right when theyre often already experiencing the higher blood sugars associated with the dawn phenomenon, and combining the two can make it harder to get levels back under control.

Additionally, beware of added sugars, syrups, and sweetened-dairy products that can quickly add empty calories to your morning brew. The difference in carbohydrate counts between one cup of black coffee and a Grande Frappuccino from Starbucks is stark and can make all the difference between a good blood sugar day and a difficult one. Having coffee beverages that are high in saturated fat and sugar on a regular basis can contribute to both insulin resistance and the development of type 2 diabetes.

Even an innocuous latte can still have anywhere between 12-25 grams of carbohydrates, simply from the sugars found in milk.

Does Coffee Raise Blood Pressure And Blood Sugar

One question that bothers quite a lot of people is whether coffee does raise blood pressure or not. If you drink coffee, this is something youd like to know the truth about.

This is very important because millions of people drink coffee everyday. And millions of people all over the world have high blood pressure. In fact, high blood pressure is leading cause of health problems in a lot of countries.

Is it possible that habitual coffee drinking may be contributing to the problem we have regarding high blood pressure worldwide? It is not impossible to think along those lines.

But I suspect such reasoning might lead us the wrong path.

Yes, millions of people drink coffee habitually. Yes, millions of people have high blood pressure. But so do non-coffee drinkers too. Occassional coffeee drinkers or those who do not drink coffeee at all for whatever reason also do suffer from high blood pressure.

Oh, lets not forget. There are those who do not drink coffee but drink lots of tea with caffeine in them. Caffeine is not only present in coffee beans but also in a lot of tea leaves too.

With many people turning to natural remedies for their health problems, it is not surprising that herbal teas like green tea and black tea have become a staple in many homes.

How Much Caffeine Is Too Much

It only takes about 200 milligrams of caffeine to affect your blood sugar. Thatâs the amount in about one or two cups of brewed coffee or three or four cups of black tea.

You may be able to handle more or less caffeine. People can have different reactions to the drug. Your response depends on things like your age and weight.

How much caffeine you usually get may also play a role. People with diabetes who are regular coffee drinkers donât have higher blood sugar levels than those who arenât. Some experts think your body gets used to that amount of caffeine over time. But other research shows that caffeine could still cause a spike, even if you always start your day with a cup of joe.

To find out if caffeine raises your blood sugar, talk to your doctor or a dietitian. You might test your blood sugar throughout the morning after you have your usual cup of coffee or tea. Then youâll test after you skip the drink for a few days. When you compare these results, youâll know if caffeine has an impact.

Cups Of Coffee A Day For Type 2 Diabetes

Coffee With Added Ingredients

If you dont have diabetes but are concerned about developing it, be careful before increasing your coffee intake. There may be a positive effect from coffee in its pure form. However, the benefits arent the same for coffee drinks with added sweeteners or dairy products.

Creamy, sugary drinks found at cafe chains are often loaded with unhealthy carbs. Theyre also very high in calories.

The impact of the sugar and fat in a lot of coffee and espresso drinks can outweigh the good from any protective effects of the coffee.

The same can be said about sugar-sweetened and even artificially sweetened coffee and other beverages. Once sweetener is added, it increases your risk of developing type 2 diabetes. Consuming too many added sugars is directly linked to diabetes and obesity.

Having coffee drinks that are high in saturated fat or sugar on a regular basis can add to insulin resistance. It can eventually contribute to type 2 diabetes.

Most big coffee chains offer drink options with fewer carbs and fat. Skinny coffee drinks allow you the morning wake-up or afternoon pick-me-up without the sugar rush.

Even for healthy individuals, the caffeine in coffee can have some side effects.

Caffeines common side effects include:
