The goal of this trial is to examine long-term effects of laparoscopic gastric bypass (LRYGB) and sleeve gastrectomy (LSG) on bone mineral density, fracture risk, and body composition ≥ 5 years post-surgery.

Detailed description

Bariatric surgery shows impressive results in terms of weight loss and resolution of comorbidities. Still, there are questions as to the frequency of long-term adverse effects: data on alterations in bone health are missing, The goal of this trial is to examine long-term effects of laparoscopic gastric bypass (LRYGB) and sleeve gastrectomy (LSG) on bone mineral density, fracture risk, and body composition ≥ 5 years post-surgery.
