In this multicenter study of 7-year weight and comorbid health changes after Roux-en-Y gastric bypass (RYGB) and laparoscopic adjustable gastric banding (LAGB), most participants maintained much of their weight loss with variable fluctuations over the long term, and comorbid health improvements were sustained after RYGB.
Of 2,348 participants, 1,738 had RYGB and 610 had LAGB. Follow-up weights were obtained in 1,300 participants after 7 years.
The 7-year mean weight loss was:
Compared with baseline, dyslipidemia was lower 7 years after both procedures. Diabetes and hypertension were lower following RYGB only. There were 59 deaths after RYGB and 15 after LAGB.
Question What are the 7-year weight and comorbid health changes following Roux-en-Y gastric bypass and laparoscopic adjustable gastric banding? Findings In this multicenter longitudinal study, 7-year mean weight loss was 28.4% with weight regain after 3 years of 3.9% for Roux-en-Y gastric bypass and 14.9% with 1.4% weight regain for laparoscopic adjustable gastric banding.
