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.

After Diabetes: Can Coffee Raise Your Blood Sugar Levels

If you are a regular coffee drinker and have been recently diagnosed with diabetes, you may notice a spike in your blood sugar levels after you down your morning latte. For some people with diabetes, caffeine can simulate a stress response that releases sugar from the liver, raising blood sugar levels. But that doesnt necessarily mean you have to give up your cuppa brew. First of all, caffeine can affect people differently, so just because it sends your friends blood sugar skyrocketing doesnt mean it will do the same to yours.

If there is a question about the coffees relationship to a rise in blood glucose, I have patients wear a continuous glucose monitoring device and we can watch the glucose response to the coffee, says Stuart Weiss, MD, clinical assistant professor of endocrinology at NYU Langone Health.

If you dont have a continuous glucose monitor, test blood sugar levels before and after you drink coffee and keep a record to show your doctor. Before you take your first sip in the morning, Dr. Weiss recommends you drink a glass of water first. Being well hydrated helps to modulate the rise seen in glucose.

Only Diabetics Get High Glucose Values

While a high glucose value can indicate diabetes, nondiabetics can also have higher values than normal. When researchers studied people wearing a continuous glucose monitor who did not have a diabetes diagnosis, they found 93% of individuals reached glucose levels that are considered dangerous, with 10% spending over 2 hours per day in these dangerous levels. Traditional glucose measurements, like a single point in time blood glucose value, are unable to capture these abnormalities.

There are actually several causes of high blood sugar unrelated to diabetes that the CDC recognizes. These include certain foods, like artificial sweeteners and coffee. Other factors like stress can do it, too. If you live with an endocrine or pancreatic condition, had surgery recently, or are experiencing intense physical stress , you may also see your glucose value rise.

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.

Why Does Coffee Affect Diabetic Patients Differently

Does Drinking Black Coffee Raise Your Blood Pressure ...

Some people complain that their blood sugar spikes up after drinking only one cup of coffee. But that does not happen to everybody. The answer to this problem is metabolism. Metabolism refers to the processes that occur in the body once the food is eaten.; If you metabolize the coffee fast, your body will be able to tolerate more and it will not spike your blood sugar. But if you are a slow metabolizer, the coffee intake will raise your blood glucose level.

Bottom line

If your blood sugar spikes after drinking coffee then you have to be careful. Always consume a balanced diet and avoid products that contain saturated fat. Try reducing the amount of sugar and creamers in your coffee. Add exercise to your daily routine. Exercise increases insulin sensitivity and reduces blood glucose.

Ways In Which Coffee Impacts Diabetes

Research has shown that people with high levels of SHBG hormone do not tend to develop diabetes. This conclusive research proves the protective benefits of coffee, but only if you already do not have the disease.

If you have diabetes or you are prediabetic, then coffee is undoubtedly bad for you. Here are three upsetting ways in which drinking coffee impacts diabetes.

  • Spike in blood sugar and insulin levels: Coffee increases bothblood sugar levelsand insulin levels in the body. The caffeine present in coffee is responsible for this rise. This means that coffee will boost sugar levels that are already high in people with diabetes. In diabetes, the body is unable to manage high sugar levels. The cells cannot absorb the glucose required for their functioning. The glucose levels in the bloodstream increase rapidly after meals, and the liver is unable to store this excess blood glucose.
  • High levels of insulin can damage the kidneys, nervous system, and even vision.

    Before Diabetes: Can Coffee Reduce Your Risk

    Perhaps the best news for coffee drinkers worried about their diabetes risk is this 2005 JAMA review: After researchers analyzed data from nine separate studies on more than 193,000 participants, they concluded that regular coffee drinking was associated with a lower risk of developing type 2 diabetes. But was the coffee itself or the caffeine responsible for the benefits?

    In various studies, as coffee and tea consumption increases, the risk of diabetes decreases, says Caroline Messer, MD, an endocrinologist at Lenox Hill Hospital. Subjects who drank six cups of coffee daily were at lower risk for diabetes than those who drank less than two cups of coffee per day. This phenomenon was observed for both caffeinated and decaffeinated beverages. This suggests that caffeine may not be the only driver behind the improvement in blood sugar levels among java lovers.

    Drinking coffee was associated with a lower risk of developing type 2 diabetes.

    A 2016 study published in the International Journal of Pharmacy and Pharmaceutical Sciences concluded that caffeine along with chlorogenic acid, a strong antioxidant found in coffee, improves insulin sensitivity and lowers levels of uric acid and sugar in the body. Too much uric acid in the blood can lead to insulin resistance and increased risk of diabetes. The study only included coffee, not tea, which implies there are certain components of coffee beyond caffeine that improve insulin sensitivity.
