Determinantes de recurrencia de peso en pacientes con cirugía bariátrica

Objective: Bariatric surgery (BS) has numerous benefits in people with obesity (PWO), but up to 30% will present weight recurrence (WR). Our objective was to recognize determinants that allow identification of PWO with higher risk of WR. Materials and method: retrospective, observational study with PWO treated with BS who assisted a specialized center due to WR. Demographic, clinical, behavioral and previous use of medication data were collec-ted. Results: n=80 (78.8% women; median age: 37 years; pre-surgical body mass index: 34.7 kg/m² [range: 26.2-57.35]); previous use of weight-loss medications: 41.3%). After a median of 8 months from BC (interquartile range [IQR]: 6-12), a median nadir excess weight loss of 101.5% (IQR: 82.7-119) was achieved. Time from BS to a first visit to a nutritionist physician was 84 months (IQR: 36-132). WR was significantly associated with age at consultation (r=0.248; p=0.027), with no significant association with medical history or preoperative drug use. A significant correlation was demonstrated between WR and craving (p=0.028) and snacking (p=0.012). GLP-1 receptor agonists were prescribed in the nutritional consultation in 82.5% of cases, as monotherapy or in combined treatment. Conclusions: certain behavioral parameters (craving, snacking) are significantly associated with WR in PWO treated with BS, reinforcing the need for a multidisciplinary approach.
