Laproscopic Roux-en-Y gastric bypass (LRYGB), although procedurally highly effective, also requires a high level of patient commitment to lifelong dietary and lifestyle changes that dictate its effectiveness. By retrospectively examining the patient files of 105 LRYGB patients throughout their first 13 months post-operation, this study anticipated to identify a statistically significant correlation between the number of times a one-year post operative LRYGB patient meets with a registered dietitian (RD) and that patient’s overall success of weight loss as determined by the rate and continued maintenance of weight loss. After evaluating the data set, it was determined that the sample size was too small to yield a statistically relevant conclusion. However, two statistically significant observations were uncovered: (1) a significant decline in weight loss in both males and females was observed in the 4th chronological month post-surgery; and (2) and as months from surgery date increased, the average percent of weight loss observed declined. One conclusion that can be drawn from these observations is that all members of the healthcare team involved with gastric bypass patients should focus particular attention on patient follow-ups and the patient’s weight-loss maintenance in the 4th chronological month post-surgery and thereafter.
