[Who are the obese people concerned by bariatric surgery today?]

Abstract

Bariatric surgery is indicated for patients with a body mass index ≥ 40 kg/m² or ≥ 35 kg/m² with comorbidities, after failure of conservative management. Its success relies on a multidisciplinary approach and personalized post-operative follow-up: control of reflux and mechanical complications for sleeve, in-depth nutritional assessment and management of malabsorption syndromes, dumping and undernutrition for bypass. Weight regain >10% of nadir weight warrants multidisciplinary reassessment.
