  • Based on early data from Asia, patients at high risk of developing severe respiratory complications from CoV-2-SARS infection causing COVID-19 disease include individuals with associated comorbidities (hypertension, cardiovascular disease, chronic lung disorders, diabetes, disorders and therapies associated with immunosuppression, cancer), and advanced age (for current synopsis see also: Federal Office of Public Health publication RS 818.101.24, supplement 6, pp. 31-33).
  • Obesity has initially not been identified as an independent risk factor for COVID-19 disease.
  • There is no evidence that the Sars-Cov-2 virus infects more obese patients than individuals with a weight considered to be within the normal range.
  • Recent evidence now suggests that patients with severe obesity (BMI ≥35 kg/m2) may be more vulnerable to the effects of CoV-2-SARS infection, and that they are at higher risk of serious complications, including the risk of requiring invasive mechanical ventilation in the event of respiratory failure (1-3).
  • Based on these data (1-3), the SGED, ASEMO and SMOB suggest that severe obesity (BMI ≥35 kg/m2; Grade 2 and BMI ≥40 kg/m2; Grade 3) be considered an independent risk factor affecting the outcomes of COVID-19 disease.
  • Individuals with severe obesity should be carefully evaluated for the presence of other risk factors and, in the case of suspected CoV-2-SARS infection, priority screening is recommended.
  • Patients with severe obesity should be counseled about protective measures to minimize the risk of contracting CoV-2-SARS infection.
