Bariatric/metabolic surgery was paused during the Covid-19 pandemic. The impact of social confinement and the interruption of this surgery on the population with obesity has been underestimated, with weight gain and worsened comorbidities. Some candidates for this surgery are exposed to a high risk of mortality linked to the pandemic. Obesity and diabetes are two major risk factors for severe forms of Covid-19. The only currently effective treatment for obesity is metabolic surgery, which confers prompt, lasting benefits. It is thus necessary to resume such surgery. To ensure that this resumption is both gradual and well-founded, we have devised a priority ranking plan. The flow charts we propose will help centres to identify priority patients according to a benefit/risk assessment. Diabetes holds a central place in the decision tree. Resumption patterns will vary from one centre to another according to human, physical and medical resources, and will need adjustment as the epidemic unfolds. Specific informed consent will be required. Screening of patients with obesity should be considered, based on available knowledge. If Covid-19 is suspected, surgery must be postponed. Emphasis must be placed on infection control measures to protect patients and healthcare professionals. Confinement is strongly advocated for patients for the first month post-operatively. Patient follow-up should preferably be by teleconsultation.
