A Case of Combined Diabetic Ketoacidosis and Hyperosmolar Hyperglycemic State in a Patient With COVID-19.

The novel coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome-corona virus-2 (SARS-CoV-2). Diabetes mellitus (DM) is one of the risk factors associated with severe illness in COVID-19 leading to increased hospital admissions and mortality. COVID-19 can precipitate hyperglycemic emergencies like diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS) in patients with DM. We present a case of a patient with COVID-19 admitted to the hospital with combined DKA and HHS. The case highlights the challenge of managing patients with DM suffering from COVID-19.
