Do High Blood Sugars Increase the Death Rate of COVID-19?

With more COVID-19 data coming in, we’re starting to see different symptoms, different severity, and different mortality among groups of people. One group is those with high blood sugars and/or Diabetes. As researchers look at the numbers, they are asking “Do high blood sugars increase the death rate of COVID-19?”

Unfortunately, it stands to reason that they would.

In fact, other infections and diseases show higher death rates in people with Diabetes and high blood sugars.

A recent study, published in the Journal of Diabetes Science and Technology shows us how high blood sugars are affecting those with COVID-19.

Do High Blood Sugars Increase Death Rate of COVID-19?

The Study

The study, which was published online earlier this month, looked at more than 1000 patients who were hospitalized with COVID-19 between March 1 and April 6 of 2020 (1).

The researchers found that patients with hyperglycemia in the hospital, who had a history of Diabetes before admission, were four times as likely to die from COVID-19 than those with normal blood sugars or without Diabetes.

What’s more, the patients who developed high blood sugars after admission, but did not have a prior diabetes diagnosis beforehand, were 7 times as likely to die.

The Numbers

The researchers observed 1122 total patients.

Of those, there were 194 patients with diabetes (A1c > 6.5%) at the time of admission.

There were 257 patients with “uncontrolled hyperglycemia (high blood sugars)” after admission. These patients did not have a known diagnosis of diabetes.

This left 671 patients that did not have diabetes nor uncontrolled hyperglycemia. Interestingly, these patients were more likely to be female and were slightly younger (average of 61 years vs. 65 years old).

The Discussion

Why would those with hyperglycemia fair the worst? Why do blood sugars matter?
High blood sugars are often seen as a complication, or contributing factor, of infection. The more the infection proliferates, the more difficult it can be to control blood sugars.
Some of the patients with high blood sugars may also have had undiagnosed diabetes going into their hospital. If this was the case, they may not have been monitored for blood sugars as soon or as intensely as those with known diabetes. Then, blood sugars may have gotten out of hand before the doctors could more easily control them.
High blood sugars can cause a cycle of destruction in the body when an infection is involved. Scientists believe, based on new lab studies and previous human studies, that high blood sugars may unleash destructive molecules that hamper the immune system.  The molecules attach to proteins causing a decreased immune response (2).

Our Fight Against High Blood Sugars

High blood sugars, dysglycemia, and obesity are at the center of many deadly diseases, and many poor outcomes from outside infections.

But, we can do something about it.

Eating in the Keto Zone can drastically reduce and normalize blood sugars, and promote fat loss. If you would like to get started with Keto Zone, try our Keto Zone 21-Day-Challenge today. It’s free. You can make a huge difference in your health by making sure blood sugars are healthy.

Bottom Line

The COVID-19 pandemic has shed even more light on the dangers of high blood sugars and infections. As you work to be your healthiest at this time, make sure you’re learning about blood sugars and how to keep them normalized. Start with working towards a healthy weight, and eat in the Keto Zone!
