Obesity is strongly associated with increased oxidative stress, chronic low-grade inflammation, and an increased risk of severe outcomes in infectious diseases like COVID-19.

Maintaining a healthy weight is critical not just for metabolic health but also for reducing the risk of severe complications from respiratory infections like COVID-19. Obesity is a major predictor of severe symptoms and critical care admission.

GoodSupportsHIGH confidence
Obesity increases the risk of hospitalization and admission to intensive care units, in addition to greater severity of the disease and higher mortality in COVID-19 patients. Underlying mechanisms include obesity-related comorbidities (T2DM, cardiovascular and renal impairments), immune system impairments, a systemic diffusion of infection, increased type 2 inflammation with effects on the lung parenchyma, raised IL-6 levels, and abnormal secretion of adipokines and cytokines inducing low-grade inflammation.
