Recent studies have shown that Covid-19 could trigger diabetes in some sections of people. Scientists have known that diabetes cases rose last year across the world as Covid-19 cases surged. This was ascertained even in those that don't have a family history of diabetes. This forced them to launch research dedicated to know the reason behind diabetes growth and see if there are links with specific conditions.

The study reported each type 1 and type 2 diabetes in samples collected across the world. In type-1 diabetes, the body attacks the cells in the pancreas that turn out internal secretion, whereas in type 2 body still produces some insulin, that isn't enough. 

Scientists currently assume that the Covid-19 virus includes a feature that can cause sugar metabolism to malfunction. Research of hospitalised Covid-19 patients showed that 14% of these developing Covid-19 have diabetes. An identical study found regarding 4.9% of patients developed diabetes.

Possible reasons :

There is a theory that disease inflicting the SARS-CoV-2 virus directly attacks insulin-producing cells within the pancreas. Another theory says that the virus may attack the pancreas' alternative part or blood vessels that provide it with oxygen(O2) and nutrients. 

Some scientists also speak that the virus attacks another organ comparable to the bowel, reducing the ability to interrupt glucose. Some Covid-19 patients are treated with steroid medicines such as dexamethasone that increase blood glucose levels. Viral infections can cause the strain hormones such as adrenal cortical steroid to increase, which may cause blood sugar levels to rise. 

Among some patients diagnosed with diabetes, their diabetic symptoms eventually went away, and their blood sugar returned to traditional levels when the infection. 

What to try and do, if you have got diabetes and contract or suspect COVID-19 :

Dr Kolterman says that sheltering in place inherently and makes things a small amount additional tricky: "Someone with diabetes wants a stockpile of diabetes paraphernalia. These patients should never run out of glucose control medications throughout this pandemic." 

He conjointly says that people with diabetes who have or suspect COVID-19 and who are not seriously sick should "double down on controlling glucose – and if they were to see that their glucose was escalating, get in touch with their healthcare provider."
