[en] Obesity represents a higher risk of severe COVID-19 infection, which may lead to the requirement of a mechanical ventilation in intensive care units and premature death. The underlying mechanisms are multiple: alteration of the respiratory performance, presence of comorbidities such as diabetes, hypertension or obstructive sleep apnea, finally inadequate and excessive immunological responses, possibly aggravated by ectopic intrathoracic fat depots. Thus, COVID-19 may challenge the so-called « obesity paradox » commonly reported by intensivists in patients with acute respiratory distress syndrome. These findings require reinforced preventive and curative measures among obese patients to limit the risk of progression towards an unfavorable outcome in case of COVID-19.
