Objective: Roux-en-Y-gastric bypass (RYGB) surgery is an effective treatment for morbid obesity. A possible overlooked side effect is negative bone metabolic consequences. Design: A seven-year prospective study following ten women and seven men after RYGB (baseline mean age 43 +/- 8 years, BMI 42 +/- 6 kg/m(2)). Methods: Lumbar spine and total hip bone mineral density (BMD) using dual energy x-ray absorptiometry, distal radius and tibia bone geometry, volumetric BMD, microarchitecture and finite element estimated bone strength using high-resolution peripheral quantitative CT and biochemical markers of bone remodelling were assessed at baseline, 2 and 7 years. Results: Compared to baseline, body weight was 24 +/- 10% lower after 2 years and 21 +/- 11% after 7 years. During the 7 years of follow-up, radius and tibia vBMD had declined 13 +/- 8% and 8 +/- 7% from baseline to 2 years and further 10 +/- 7% and 7 +/- 8% from 2 to 7 years (all P < 0.001). At both radius and tibia, cortical thickness declined and cortical porosity increased. From baseline to 7 years, there were clear indications of deteriorations of the trabecular network with fewer, more widely spaced and more in-homogeneously distributed trabeculae in both radius and tibia. Overall, declines in estimated bone strength of 16 +/- 9% in radius and 16 +/- 7% in tibia were observed (both P < 0.001). Conclusion: Seven years after RYGB, evidence of continuous declines in BMD and ongoing deterioration of bone microarchitecture and reduced estimated bone strength compared to baseline and 2 years post-surgery results were found. These findings emphasize the need for regular assessment of bone health in patients with prior RYGB.
