Impact of bariatric surgeries on bone density in patients with severe obesity

Abstract

Metabolic and bariatric surgery is associated with changes in bone mineral density, most notably after gastric bypass procedures, accompanied by reductions in calcium and vitamin D levels and increased parathyroid hormone. These findings underscore the importance of early postoperative monitoring of bone health using DXA and biochemical markers, particularly after bypass procedures and in patients with poor adherence to supplementation.
