COVID & Diabetes Managing Blood Sugar Levels Discussion

Diabetes and COVID-19 onset symptoms, long term effect and complications

Coronavirus can cause inflammation, hormonal imbalance in the body, blood clots and other serious health conditions. Some of asymptomatic, mild, moderate or severely affected patients have elevated levels of blood sugar.

It’s possible these patients have prediabetes (when your blood sugar levels are higher but can’t be classified as diabetes) or preexisting condition before SARS-CoV-2 infection, due to steroid and insulin-dependent treatment diabetes triggered. In these patients, COVID-19 can affect blood sugar levels that cause diabetes after covid recovery may remain for their lifetime. 

It has been observed 25 to 30% of patients treated in hospital due to severe symptoms developed diabetes or high blood sugar level after COVID-19 recovery.

As per recent studies, coronavirus spike protein can cause damage to pancreas beta cells that is responsible to secrete insulin, due to cells damage pancreas is not able to maintain normal blood sugar levels and regulate glucose into the body's cells.

Respiratory viral infection can elevate blood sugar level, these are the warning signs that may indicate that the person might have developed diabetes mellitus during COVID-19 infection or post recovery:

  1. Excessive, frequent urination and excessive thirst (diabetes insipidus)
  2. Blurry vision and loss of alertness
  3. Slow Healing of cuts and wounds

Patients with diabetes already at risk of developing complications like nerve damage (neuropathy), kidney damage (nephropathy), eye damage (retinopathy), skin diseases, cardiovascular disease etc.


I'm a Type 2 diabetic and I use insulin to control my blood sugars. After being vaccinated, my insulin needs tripled. I was wondering what caused it. Now I know. 

I was symptomatic with COVID in Dec of 2020. I still am still loaded with antibodies and did not get vaxxed. I am 48 not diabetic and noticing similar blood sugar issues with my diet in the last 12 months where I need to watch my carbohydrate intake. Nothing severe just minor headaches sometimes when I have a lot of carbs and/or hoppy beer / red wine.

My friend’s husband has type 1 diabetes and was forced to take the jab or lose his job to provide for his family. He took the Moderna jab and he had severe inflammation and was bed ridden for a week and had to quadruple his insulin intake. His blood sugar is still not normal to this day and it’s been more than 6 months. He was going to take the second shot because of work until his doctor called and recommended him to not take the second shot because a patient of his with similar side affects to the first jab as him had just passed away from the second jab.

My dad has had a 6 pack since before I was born, and he suddenly has prediabetes out of nowhere... I'm searching for answers for him.

One of the girls at my work said she has been doing everything the same, eating better, and even lost some weight but can’t seem to manage her hga1c since getting vaxxed. Could be just a coincidence.
