Stable blood sugar levels can mitigate your risk level.
It’s natural to be nervous about the COVID-19 pandemic—especially if you have diabetes. People with diabetes are an “at-risk” group because they are more likely to have serious complications of COVID-19.
However, you can reduce your risk. Early statistics show that people with stable blood sugar levels likely have a lower risk of serious complications, compared to those with high or unstable levels.
“The most important thing someone with diabetes can do to lower their risk of COVID-19 complications is to control their blood glucose, control their blood pressure, control their body weight, and to practice social distancing, hand hygiene, and mask wearing,” says Minisha Sood, MD, endocrinologist.
The Role of Blood Sugar Levels
High blood sugar levels can have many effects on the body. For example, it can damage the blood vessels (increasing the risk of cardiovascular diseases) and the nerves (leading to neuropathy). Learn more here about complications of diabetes.
Additionally, “high blood sugars compromise the immune system's ability to fight off infections, including COVID-19,” says Dr. Sood.
The high blood sugar both causes chronic inflammation in the body and triggers something called a cytokine storm. This is “an overreaction of the immune system which could lead to severe complications of COVID-19,” says Dr. Sood. “It could increase the risk of hospitalization or more severe pneumonia or respiratory failure.”
Managing Your Risk
There are actions you can take to reduce your risk of serious complications. For starters, it’s important to stick to your treatment plan during the pandemic. You should continue:
- Taking your medications and insulin as prescribed
- Eating a diabetes-friendly diet
- Staying physically active (like taking a walk)
- Checking your blood sugar regularly
You might also want to take additional precautions during the pandemic. For example, you can make an action plan with your doctor so you know what to do if you get sick. You should also make sure you always have at least a 30-day supply of your medications.
“If someone is having trouble managing their diabetes during the COVID-19 pandemic, it's important to get in touch with your healthcare provider,” says Dr. Sood. “Make sure that you not only have enough medications and testing materials, but also to discuss any symptoms that are arising because early treatment could be life-saving.”
Dr. Sood is a board-certified endocrinologist in private practice in New York City and an assistant professor at Hofstra School of Medicine.

00:00:01.933 --> 00:00:04.332
The most important thing someone with diabetes can do
00:00:04.333 --> 00:00:06.999
to lower their risk of COVID-19 complications
00:00:07.000 --> 00:00:08.932
is to control their blood glucose,
00:00:08.933 --> 00:00:10.832
control their blood pressure,
00:00:10.833 --> 00:00:12.532
control their body weight,
00:00:12.533 --> 00:00:14.766
and to practice social distancing,
00:00:14.767 --> 00:00:17.366
hand hygiene, and mask-wearing.
00:00:17.367 --> 00:00:22.332
00:00:22.333 --> 00:00:25.666
High blood sugars compromise
the immune system's ability
00:00:25.667 --> 00:00:28.432
to fight off infections, including COVID-19.
00:00:28.433 --> 00:00:31.299
The high blood sugar environment in the body
00:00:31.300 --> 00:00:32.832
does a few things.
00:00:32.833 --> 00:00:35.332
First of all, it leads to chronic inflammation.
00:00:35.333 --> 00:00:38.532
Second of all, this may trigger a cytokine storm,
00:00:38.533 --> 00:00:40.566
or an overreaction of the immune system,
00:00:40.567 --> 00:00:43.732
which could lead to severe complications of COVID-19.
00:00:43.733 --> 00:00:46.666
It could increase the risk of hospitalization,
00:00:46.667 --> 00:00:50.499
or more severe pneumonia or respiratory failure,
00:00:50.500 --> 00:00:55.432
and also, it can lead to potential diabetic ketoacidosis.
00:00:55.433 --> 00:00:58.166
Diabetic ketoacidosis is a condition in the body
00:00:58.167 --> 00:01:00.699
where the body's ability to make enough insulin
00:01:00.700 --> 00:01:03.932
to deal with the stress of the infection is impaired,
00:01:03.933 --> 00:01:05.832
and without enough insulin around,
00:01:05.833 --> 00:01:08.466
and higher blood sugars because of the stress
00:01:08.467 --> 00:01:10.566
that the body is experiencing,
00:01:10.567 --> 00:01:13.432
the body makes acids called ketones,
00:01:13.433 --> 00:01:16.632
and ketones change the biochemistry of the blood,
00:01:16.633 --> 00:01:20.032
and that can lead to dehydration, nausea,
00:01:20.033 --> 00:01:21.999
vomiting, and electrolyte problems,
00:01:22.000 --> 00:01:26.099
and immediate medical attention is needed
for life-saving measures.
00:01:26.100 --> 00:01:28.899
Someone with diabetes can minimize their risk
00:01:28.900 --> 00:01:32.132
of severe complications by controlling blood glucose levels,
00:01:32.133 --> 00:01:33.932
controlling body weight,
00:01:33.933 --> 00:01:35.299
controlling blood pressure,
00:01:35.300 --> 00:01:37.599
and making sure that they have an ample supply
00:01:37.600 --> 00:01:40.899
of medication and testing materials on hand,
00:01:40.900 --> 00:01:42.799
and also an open line of communication
00:01:42.800 --> 00:01:45.632
with their healthcare provider should issues arise.
00:01:45.633 --> 00:01:47.866
If someone is having trouble managing their diabetes
00:01:47.867 --> 00:01:49.499
during the COVID-19 pandemic,
00:01:49.500 --> 00:01:52.432
it's important to get in touch with your healthcare provider
00:01:52.433 --> 00:01:55.066
to make sure that you not only have enough medications
00:01:55.067 --> 00:01:56.299
and testing materials,
00:01:56.300 --> 00:01:59.166
but also to discuss any symptoms that are arising
00:01:59.167 --> 00:02:02.567
because early treatment could be life-saving.
