Prolonged hyperglycemia in three patients with type 2 diabetes after COVID-19 infection: A case series

Three independent cases of adult patients are described who had relative control of their type 2 diabetes prior to infection with COVID-19. Each of the described patients had different levels of severity of COVID-19 but all experienced significant and prolonged hyperglycemia for at least 1–2 months after resolution of their COVID-19 infection. Two of the three patients required intensifying insulin regimens for two months after COVID-19 infection. The case study helps to inform primary care providers about the possible need for the intensification of antihyperglycemic medications for several weeks to months after the resolution of COVID-19 infection to minimize prolonged hyperglycemia.
