Alterations in Fat Mass and Bone Mineral Density Are Associated with Decreased Lipocalin-2 After Laparoscopic Sleeve Gastrectomy in Obese Chinese Women

Objective Lipocalin-2 (LCN2) plays an important role in the regulation of the obesity and obesity-related dysmetabolic state. This study aimed to analyze serum LCN2 level in Chinese women with obesity before and after laparoscopic sleeve gastrectomy (LSG) and determine the association between alteration in fat mass and bone mineral density (BMD) and LCN2 level.
