Does Covid-19 trigger diabetes in some individuals?

A brand new analysis paper revealed in the International Journal of Endocrinology and Metabolism has now warned of the onset of diabetes post-Covid-19 in some individuals with none blood sugar points, or household historical past regardless of Body Mass Index (BMI) and age. The analysis paper’s creator, Dr Rujuta Katkar, talked about a collection of observations amongst eight sufferers aged between 36 and 74 years, reported MidDay. These sufferers, in response to Dr Katkar, had no medical historical past and even household historical past of diabetes however developed it after Covid-19. Indianexpress.com reached out to specialists to know how widespread is diabetes in Covid-19 sufferers, which is being termed as Covid diabetes.

“Yes, we have been seeing increased incidences of diabetes and worsening of existing diabetes post-covid infection also. There is evidence that the covid virus per se can cause some damage to the beta cells,” mentioned Dr Jugal Gada, endocrinologist, Bhatia Hospital, Mumbai.

Why is it a fear?

Since practically one in six individuals with diabetes in the world are from India, also referred to as the world’s diabetes capital.


According to Dr Saket Kant, senior guide, diabetes and endocrinology, Sri Balaji Action Medical Institute, Gurugram, Covid selectively binds to and destroys beta cells in the pancreas that are answerable for insulin secretion.

“During Covid treatment, patient’s physical activities are restricted. As a result, bed rest covid patients tend to eat more than the physical activities they indulge in,” mentioned Dr Kant.

This raises the danger of excessive blood sugar. As per World Health Organization (WHO), hyperglycaemia, or raised blood sugar, is a typical impact of uncontrolled diabetes and over time results in severe injury to most of the physique’s programs, particularly the nerves and blood vessels.

According to a paper revealed in NEJM.org, there’s a bidirectional relationship between Covid-19 and diabetes. “On the one hand, diabetes is associated with an increased risk of severe Covid-19. On the other hand, new-onset diabetes and severe metabolic complications of preexisting diabetes, including diabetic ketoacidosis and hyperosmolarity for which exceptionally high doses of insulin are warranted, have been observed in patients with Covid-19,” the 2020 paper famous.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes Covid-19, binds to angiotensin-converting enzyme 2 (ACE2) receptors, that are expressed in key metabolic organs and tissues, together with pancreatic beta cells, adipose tissue, the small gut, and the kidneys, states the paper.

‘Thus, it is plausible that SARS-CoV-2 may cause pleiotropic alterations of glucose metabolism that could complicate the pathophysiology of preexisting diabetes or lead to new mechanisms of disease,’ it reads.

How is steroids administration associated to Covid diabetes?

Many sufferers are given steroids as a part of their Covid therapy, which impacts their glucose degree, talked about Dr Kant. According to Dr Gada, steroids for covid can worsen blood glucose ranges much more. Insulin turns into crucial if you’re on steroids and even with out steroids, if sugars are very excessive for optimum administration of covid and to stop secondary infections, there are possibilities of diabetes onset,” mentioned Dr Gada.

What could be accomplished?

A excessive index of suspicion for new-onset diabetes needs to be saved because of the worsening of glycemic management throughout and post-Covid. For this, common consultations and investigation as suggested by the treating doctor is paramount, mentioned Dr Kant.

“Early diagnosis/intensification of treatment, graded physical activity, and diet control are the keys to good results,” mentioned Dr Kant.
