Nutrition Care in Bariatric Surgery

Nutrition Care in Bariatric Surgery

Welcome to the Nutrition Care in Bariatric Surgery Systematic Review. The 2017 expert workgroup focused on four (4) subtopic areas:

• Post-operative Medical Nutrition Therapy
• Post-operative Energy Needs
• Post-operative Energy Intake
• Post-operative Macronutrient Intake

Key Findings:  This systematic review found that undergoing bariatric surgery resulted in a clinically meaningful and statistically significant decrease in resting metabolic rate (RMR), as high as 26% at one year post-surgery, which was sustained at two years. As expected, there was a clinically meaningful and statistically significant reduction in post-operative self-reported energy intake, which was a high as 72% in the first six months after surgery but only 28% to 38% at four and five years post-surgery. No statistically significant relationship was found between post-operative macronutrient distribution and post-operative weight loss. Patients receiving medical nutrition therapy (MNT) from a registered dietitian nutritionist (RDN) for two to six visits during the first year post-surgery had a significant excess weight loss ranging from 60% to 80% and significant reduction in body mass index (BMI) ranging from 5% to 31% at 12 months. However, research is limited regarding the effect of post-operative MNT on behavior change.
