Abstract

© 2014 American Society for Metabolic and Bariatric Surgery. All rights reserved. Background: Bariatric surgery has been shown to be effective in resolving co-morbid conditions even in patients with a body mass index (BMI) < 35 kg/m2. A question arises regarding the metabolic benefits of bariatric surgery in metabolically healthy but morbidly obese (MHMO) patients, characterized by a low cardiometabolic risk. The objective of this study was to assess the effects of bariatric surgery on cardiometabolic risk factors among MHMO and metabolically unhealthy morbidly obese (MUMO) adults. Methods: A nonrandomized, prospective cohort study was conducted on 222 severely obese patients (BMI > 40 kg/m2) undergoing either laparoscopic roux-en-Y gastric bypass or laparo-scopic sleeve gastrectomy. Patients were classified as MHMO if only 1 or no cardiometabolic factors were present: high blood pressure, triglycerides, blood glucose (or use of medication for any of these conditions), decreased high-density lipoprotein-cholesterol (HDL-C) levels, and insulin resistance defined as homeostasis model assessment for insulin-resistance (HOMA-IR) > 3.29. Results: Forty-two (18.9%) patients fulfilled the criteria for MHMO. They were younger and more frequently female than MUMO patients. No differences between groups were observed for weight, BMI, waist and hip circumference, total and LDL-C. MHMO patients showed a significant decrease in blood pressure, plasma glucose, HOMA-IR, total cholesterol, LDL-C and triglycerides and an increase in HDL-C 1 year after bariatric surgery. Weight loss 1 year after bariatric surgery was similar in both groups. Conclusion: Eighteen percent of patients with morbid obesity fulfilled the criteria for MHMO. Although cardiovascular risk factors in these patients were within normal range, an improvement in all these factors was observed 1 year after bariatric surgery. Thus, from a metabolic point of view, MHMO patients benefited from bariatric surgery.
