COVID-19 Symptoms: What People with Diabetes Need to Know
Having symptoms? Call your doctor ASAP.

While there’s still a lot to learn about COVID-19, early statistics show that people with diabetes have a higher risk of serious COVID-19 complications. For this reason, it's important to know the COVID-19 symptoms for people with diabetes, so you can take action at the first sign of illness.
The Common Symptoms of COVID-19
The most common symptoms of COVID-19 include:
- Fever
- Cough
- Shortness of breath
Other possible symptoms that many patients have experienced include:
- New loss of smell or taste
- Sore throat
- Fatigue
- Muscle or body pains
- Congestion
- Nausea
- Diarrhea
Additionally, people with diabetes should be on the lookout for “an unusual spike in blood glucose levels that can’t be otherwise explained,” says says Minisha Sood, MD, endocrinologist in New York City. This could signal that you’re fighting an infection. (Here are other possible causes of high blood sugar.)
What to Do When Symptoms Appear
“If a person is noticing symptoms of COVID-19, it's important to take all their usual medications, to check their temperature, to self-quarantine, and get in touch with a healthcare provider right away,” says Dr. Sood.
For the safety of you and others, most doctors recommend calling your provider before going to the hospital. When you call, you should know your glucose reading, your ketone reading, your symptoms, and when your symptoms started.
Signs of an Emergency
People with diabetes have a higher risk of serious COVID-19 complications, so it’s important to know the signs of an emergency. You may be able to manage mild symptoms at home, but these symptoms require emergency medical attention:
- Difficulty breathing
- Pain or pressure in the chest
- Confusion
- Inability to arouse or awaken
- Bluish lips or face
These are symptoms of serious complications of COVID-19, which can be life-threatening.
The best thing you can do is be cautious. Wash your hands frequently, avoid crowded areas, and practice social distancing. Learn more COVID-19 prevention tips for at-risk groups here.
Dr. Sood is a board-certified endocrinologist in private practice in New York City and an assistant professor at Hofstra School of Medicine.

00:00:02.000 --> 00:00:04.266
It's important to know the symptoms of COVID-19
00:00:04.267 --> 00:00:05.732
if you have diabetes
00:00:05.733 --> 00:00:09.066
because early medical attention can be life-saving.
00:00:09.067 --> 00:00:13.666
(piano music)
00:00:13.667 --> 00:00:16.432
The most common symptoms of COVID-19 are fever,
00:00:16.433 --> 00:00:18.499
dry cough, shortness of breath.
00:00:18.500 --> 00:00:20.966
Other symptoms may include body aches,
00:00:20.967 --> 00:00:23.332
new loss of taste or smell,
00:00:23.333 --> 00:00:25.866
nausea, and diarrhea.
00:00:25.867 --> 00:00:28.799
If a person is noticing symptoms of COVID-19,
00:00:28.800 --> 00:00:32.299
it's important to take all their usual medications,
00:00:32.300 --> 00:00:33.966
to check their temperature,
00:00:33.967 --> 00:00:35.466
to self-quarantine,
00:00:35.467 --> 00:00:37.966
and get in touch with a healthcare provider right away.
00:00:37.967 --> 00:00:40.432
In terms of possible early symptoms
00:00:40.433 --> 00:00:42.066
in patients with diabetes,
00:00:42.067 --> 00:00:43.699
with respect to COVID infection,
00:00:43.700 --> 00:00:45.066
my recommendation would be
00:00:45.067 --> 00:00:47.499
to watch for an unusual spike
00:00:47.500 --> 00:00:50.232
in blood glucose levels that can't be otherwise explained.
00:00:50.233 --> 00:00:53.666
Before calling your doctor, it's important to note,
00:00:53.667 --> 00:00:55.399
what is your blood glucose level,
00:00:55.400 --> 00:00:56.999
what is your body temperature,
00:00:57.000 --> 00:00:58.899
what exactly are your symptoms,
00:00:58.900 --> 00:01:00.332
when did they begin,
00:01:00.333 --> 00:01:02.466
and if applicable,
00:01:02.467 --> 00:01:05.099
whether or not ketone testing has been performed
00:01:05.100 --> 00:01:06.999
and the results of that testing.
00:01:07.000 --> 00:01:09.832
Some of the complications of COVID-19
00:01:09.833 --> 00:01:13.366
include pneumonia, respiratory failure,
00:01:13.367 --> 00:01:15.466
heart issues or heart failure,
00:01:15.467 --> 00:01:17.266
and also septic shock.
00:01:17.267 --> 00:01:19.166
Some emergency warning signs
00:01:19.167 --> 00:01:21.666
of the more severe complications of COVID-19
00:01:21.667 --> 00:01:24.099
include dehydration,
00:01:24.100 --> 00:01:25.966
decrease in urine output,
00:01:25.967 --> 00:01:28.799
deep coughing, chest pain,
00:01:28.800 --> 00:01:30.999
worsening fever,
00:01:31.000 --> 00:01:32.632
swelling in the body,
00:01:32.633 --> 00:01:37.066
and profound, progressive diarrhea.
00:01:37.067 --> 00:01:40.399
If you think you're experiencing symptoms of COVID-19
00:01:40.400 --> 00:01:44.166
or a progression towards more severe complications
of COVID-19,
00:01:44.167 --> 00:01:46.966
it's important to contact your healthcare provider
right away
00:01:46.967 --> 00:01:50.033
because early treatment can be life-saving.
