Incidence of New-Onset Diabetes and Hyperglycemia in COVID-19 Patients: A Family History-Based Study

Aim: To investigate the association between COVID-19 and the onset of diabetes in patients with and without a family history of the disease. Methods: Blood glucose tests were performed on patients who had close contact with COVID-19 and had infected individuals admitted to the hospital. Patients were categorized into five groups based on their diabetes status: (1) diagnosed with diabetes before COVID-19, (2) diagnosed with diabetes after COVID-19, (3) hyperglycemia after COVID-19, (4) pre-existing diabetes before COVID-19, and (5) without diabetes. Results: Among the COVID-19 positive patients, 34.69% had a family history of diabetes. Regardless of familial history, COVID-19 patients showed a predisposition to diabetes. However, individuals with a family history of diabetes were found to be more susceptible to developing the condition. Conclusions: This study highlights the increased risk of developing diabetes in COVID-19 patients, regardless of a family history of the disease. However, individuals with a family history of diabetes should be particularly vigilant. Early identification and management of COVID-19-associated diabetes, especially in high-risk populations, such as those with a family history of diabetes, are essential.
