What you need to know about COVID-19 if you have diabetes

by Fitcoachion | Last Updated: April 17, 2020



Preliminary data from China suggest that people with diabetes and other preexisting conditions are more likely to experience serious complications and death from COVID-19 than people without diabetes and other conditions.

But COVID-19 and the coronavirus that causes it are new, and researchers are still investigating how they impact immunity. We also know that if a person has diabetes and gets influenza or another infection, they can experience worse health outcomes. The question is why.

High blood sugars can interfere with white blood cells’ ability to fight infection. So there’s a possibility that people with high blood sugars may have a suppressed immune system, leaving them more susceptible to lung complications. There’s not enough data yet to know if there is a link between blood sugar control and COVID-19 outcomes.

Preparation and precautions are the best protection

Fortunately, we can still help protect people with diabetes with the information we do know. If you have type 1 or type 2 diabetes, take the following steps to prepare and reduce your risk of infection:

If you have diabetes and get sick with COVID-19

It’s critically important for people with diabetes to understand that COVID-19 illness can raise their blood pressure levels, and high blood pressure can lead to dehydration. If you get sick, drink plenty of fluids and check your blood pressure regularly. Ask your doctor for instructions on how to watch your blood pressure and adjust for changes.

In addition, check your blood sugar more frequently (about every six hours) and contact your doctor if it stays above 250 mg/dL. If you have type 1 diabetes and your blood sugar rises above 250, you could be at risk for ketoacidosis, which occurs when the body burns fat for energy and creates high levels of blood acids, known as ketones. Eventually these ketones can poison the body. During the coronavirus outbreak, it’s especially important to keep your ketone levels down and avoid trips to the ER, when possible.

Overall, having diabetes does put you at risk for COVID-19 complications, including the need for hospitalization and a ventilator. Do your best to avoid getting sick and needing care at the hospital.

Prioritize your emotional well-being

It’s also important to prioritize your mental health, which can have a big impact on your diabetes and blood sugar levels. People with diabetes are two to three times more likely to have depression. Take extra care to do things that make you happy. Breathe in deeply and slowly when you feel anxious. Talk to loved ones regularly. Use technology to stay connected to friends and family; try an online meeting or call a friend.

Your routine has been disrupted, so it’s also important to continue to get enough sleep, eat healthy, and exercise within your ability.

And above all, remember that this is a unique season of life. It won’t always be this way.
