Bariatric Surgery and Skeletal Health

March 20, 2018 updated by: Elaine W. Yu, Massachusetts General Hospital

Effects of Bariatric Surgery on Skeletal Health

Bone loss may occur after bariatric (weight loss) surgery, but standard methods of measuring bone density in obese patients are potentially inaccurate. This study uses quantitative computed tomography to examine changes in bone mineral density after bariatric surgery. We are also studying mechanisms which may explain bone loss after bariatric surgery.
