Body composition and remission of comorbidities in patients submitted to roux-en-y gastric bypass surgery.

Published on: 2018-10-26


The aim of our study is to assess the body composition and to associate it with the remission of comorbidities in morbidly obese people who undergone the Roux-en-Y gastric bypass (RYGB) surgery. A retrospective cohort study was conducted with patients that underwent Roux-en-Y gastric bypass(RYGB) surgery in 2010 and 2011. Anthropometric, biochemical and body composition data were collected preoperatively and postoperatively at 12 months and 24 months. 49 individuals with an average age of 39.3 ± 13.0 years and were overweight by 51.7 ± 21.0 kg were included in the study. Metabolic syndrome was found in 79.6% of the individuals preoperatively. The group of women presented older age (p = 0.048), lower weight (= 0.48) and higher rates of insulin (p = 0.034) when compared to the group of men. The evaluation of the best cutoff point for the percentage of fat considering the remission of comorbidities at 12 months postoperatively resulted in a value below 34% (95% CI: 53.9% to 85.9%), while at 24 months postoperatively it is a value below 30.5% (95% CI: 42.7% to 85.4%). The percentage of body fat reduces thein dependent comorbidities reduction of body weight. We also note that the recommended body fat percentage for post-bariatric patients only exists for the"normal"population, (and should exist for a spectrum encompassing all bariatric patients).
