Do Roux-en-Y gastric bypass patients meet the dietary guidelines?
Archives of Public Health volume 72, Article number: P4 (2014)
The prevalence of obesity has increased to epidemic proportions and, as a result, the number of bariatric surgeries has increased worldwide. To date, bariatric surgery remains the sole medical intervention that achieves considerable and sustained weight loss. As both obesity and bariatric surgery are associated with nutritional deficiencies, the aim of this study was to evaluate the dietary intake of macro- and micronutrients in patients before and after Roux-en-Y gastric bypass (RYGB).
A prospective observational study was performed at University Hospitals Leuven, Belgium. Patients completed a dietary record of two non-consecutive days before RYGB and 1 and 3 months after RYGB. Intake of macronutrients and micronutrients was calculated for the different time-points. Paired sample t-tests were performed to analyse differences between time-points.
The intake of macro- and micronutrients is markedly decreased one month after RYGB. At three months post-surgery, the intake of macronutrient increases, but the micronutrient intake remains identical at a worryingly low level. Our data clearly suggest that nutritional guidance is essential following bariatric surgery.
