Obese and diabetic individuals typically exhibit uncontrolled blood glucose levels, which are associated with a greater risk of developing severe COVID-19 infection. SARS-CoV-2 infection in these patients may trigger a cytokine storm, potentially driven by a dysfunctional adaptive immune response and epithelial cell death.

Obesity, Diabetes, and Elevated Blood Glucose as Risk Factors for Severe COVID-19

During SARS-CoV-2 infection, elevated glucose levels and sustained aerobic glycolysis in monocytes directly promote viral replication, cytokine production, T cell dysfunction, and lung epithelial cell death.
