Obesity exacerbates COVID-19 severity through metabolic and immune mechanisms, specifically by upregulating ACE2 receptors, promoting a 'cytokine storm' via adipokines (leptin, IL-6), and causing immune system attenuation.

Obesity isn't just about weight; it creates a state of chronic inflammation and immune dysregulation. This makes your body more likely to overreact to the virus (cytokine storm) and less able to fight it effectively. Managing metabolic health (blood sugar, blood pressure) is crucial for reducing this internal inflammatory burden.

ModerateSupportsMEDIUM confidence
literature data state that there is a direct metabolic link between the state of inflammation... and the 'cytokine storm' contributing to the respiratory decline of coVid-19 patients... obesity can reduce immune cell functionality, induce gut microbiome/virome imbalance, inflammatory cytokine phenotype and increase antiviral, antimicrobial and anticoagulant resistance
