Abstract

Objective: Weight outcomes after bariatric surgery are due to an adequate adjustment of eating behavior to the new gastrointestinal conditions created by operation. The efficacy of dietary/behavior counseling for promoting weight loss and maintenance in a growing number of bariatric patients was investigated.

Material and methods: One hundred seventy-six non-diabetic obese patients undergoing Roux-en-Y gastric bypass (RYGBP) and sleeve gastrectomy (SG) were investigated. The first group (CO, 88 subjects, 16 male) attended a standard surgical follow-up, while in the second (DIET, 88 subjects, 15 male) the surgeon was supported by a dietitian, and patients received behavioral-dietary sessions on individual request. Data prior to the operation and at 2 years were considered, the weight outcome being regarded as successful when postoperative body mass index (BMI) value was lower than 30 kg/m2.

Results: Weight results were better (p < 0.01) in the RYGBP than in the SG patients. In comparison to CO, in the DIET group a greater adherence to the bariatric program was observed (76% vs. 41%, < 0.01), while body weight data and prevalence of successful cases at 2 years (87 ± 23 vs. 83 ± 16 kg and 27% vs.33%, respectively) were similar.

Conclusions: After RYSG and SG, postoperative dietetic/behavioral sessions delivered on patient's request does not influence weight results. The dietetic intervention promotes the adherence to bariatric program and prevents postoperative follow-up loss. In a dietitian/behavioral strategy after RYGBP and SG, a cognitive reinforcement of the compliance to bariatric program and a strengthening of the motivation to changes could promote better weight results.
