The global prevalence of obesity and its related comorbidities including cancer are on the rise. Bariatric surgery is the most effective and durable method for treating obesity. Bariatric surgery also significantly reduces the risk of complications associated with obesity comorbidities, such as diabetes and cardiovascular disease, and the risk of mortality in comparison with medical management. Due to accreditation efforts, the safety profile of bariatric surgery is equivalent or superior to many common operations. The current bariatric procedures produce significant and durable weight loss and substantially reduce the morbidity and mortality associated with obesity-related diseases.
The COVID-19 pandemic is wreaking havoc on society, especially health-care systems, including disrupting bariatric and metabolic surgery. This review highlights and collects the bariatric and metabolic surgery during and after the COVID-19 pandemic. It is expected to provide reference for this operation in the new era.
