Please note that this is a preliminary finding. More research is needed to establish whether COVID-19 can cause diabetes.
In the past, viral infections have been linked to the first time a patient had diabetes symptoms, as viral infections may trigger the destruction of the insulin-producing islet cell “factories” in the pancreas, setting up a chronic autoimmune response. There are recorded cases of acute diabetes developing during mumps and enterovirus infections as well as significant evidence linking one particular enterovirus (Coxsackie-B1), with classical autoimmune type 1 diabetes.
Can COVID-19 Cause Diabetes? – RetinaRisk
COVID-19 may be causing otherwise healthy individuals to develop diabetes for the first time. According to the scientists, there’s a two-way relationship between COVID-19 and diabetes that deserves our attention. On one hand, having diabetes increases the risk of severe COVID-19 symptoms. On the other, COVID-19 seems to cause new-onset diabetes and severe metabolic complications of preexisting diabetes, including diabetic ketoacidosis and hyperosmolarity for which exceptionally high doses of insulin are warranted.
