Factors associated with different patterns of weight change after bariatric surgery: A longitudinal study

Background The mean weight loss (WL) after successful bariatric surgery is approximately one third of the initial body weight, which mainly achieved between first 2 years follow-up. However, 15–35% patients do not achieve a significant percentage total WL (%TWL). Information on factors associated with higher or lower limited. This study aimed to assess change in %TWL and describe greater lesser over time. Methods prospective longitudinal included treated laparoscopic Roux-en-Y gastric bypass sleeve gastrectomy. Baseline data were recorded before surgery. Follow-up was performed at 3 (n = 141), 6 208), 9 115), 12 216), 24 166), 36 months 99). Generalized estimating equation analysis changes time different patterns WL. Results In total, 231 (women, 82.2%; basal mass index 41.4 ± 5.1 kg/m2). tendencies increase (32 6.5) evident year stabilized thereafter. Sustained nutritionist follow-up (2.3%, p 0.004), baseline BMI >40 kg/m2 (0.4%, < 0.001), ≥10 kg (0.3%, 0.001) %TWL. Patients who physical activity >30 minutes/day reduced their by 0.6% (p 0.002).
