[Metabolic, clinical and body composition changes in Mexican adults undergoing bariatric surgery].

Background

morbid obesity is a major public health problem that is increasing. Currently, there are a limited number of studies carried out in the Mexican population that describe the effects of bariatric surgery.

Objective

to establish in obese people who undergoing weight loss surgery, the metabolic and body composition difference before and after bariatric surgery. Material and methods: an observational, analytical, and longitudinal study was carried out in 50 patients with morbid obesity who underwent laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). Body composition and metabolic markers in blood were measured. Differences in the metabolic profile before and after surgery were analyzed in the entire study group and a subanalysis was performed by bariatric surgical technique. It was also determined the percentage of remission of comorbidities.

Results

after the intervention, there is a significant decrease in all metabolic and body composition markers, except HDL cholesterol, which showed a tendency to increase without being significant. Women with LRYGB have a greater decrease in fat-free mass. LRYGB decreased the prevalence of fatty liver, gastroesophageal reflux, insulin resistance, and hypercholesterolemia more, while LSG decreased the prevalence of hypertension, osteoarthritis, hypothyroidism, and hypertriglyceridemia more.

Conclusion

bariatric surgery induces metabolic changes that could contribute to improving comorbidities associated with obesity. In general, metabolic improvement is greater in LRYGB compared to LSG.
