The novel Coronavirus disease-2019 (COVID-19) is an infectious disease due to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) that caused many health complications. The present study was conducted to provide the link between COVID-19 disease and hyperglycemia as a risk factor for the development of Diabetes mellitus. The study enrolled fifty patients with infected Covid-19 in the Raparin District-Kurdistan region-Iraq. The following parameters were included such as hemoglobin A1C (HbA1c level), serum blood sugar, blood group, body mass index (BMI). The covid-19 patients were 56% males and 44% females with different ages, jobs, and blood groups. The mean age of patients was 51.22 (±12.29) years old. The COVID-19 patients who developed diabetes were (96%) and diabetes risk were (4%). It can be concluded that COVID-19 infection may leads to development diabetes resulting from hyperglycemia.
