Seven-year outcomes after bariatric surgery

By: Judy Mathias

Editor’s Note

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:

  • 28.4% for RYGB, with weight regain after 3 years of 3.9%
  • 14.9% for LAGB, with weight regain after 3 years of 1.4%.

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.
