Sclerostin levels and changes in bone metabolism after bariatric surgery.

Context: The role of sclerostin as a key regulator of bone formation remains unknown after Roux-en-Y gastric bypass (RYGB) or laparoscopic sleeve gastrectomy (SG).

Objectives: The study objectives were evaluation of sclerostin and Dickkopf-1 (DKK-1) serum levels after surgery and correlations with bone turnover markers (P1NP, CTX), parathyroid hormone (iPTH) and areal bone mineral density (BMD), changes at total body, lumbar spine and total hip.

Design And Setting: This was a prospective observational single-center two-arm study in premenopausal women with acute adipositas over 24 months.
