Kaderli RM, et al. - This study assessed the preoperative risk factors for "hungry bone syndrome" (HBS), especially emphasizing on the influence of 25-hydroxyvitamin D (25(OH)D) deficiency. Findings demonstrated no relation between preoperative 25(OH)D deficiency and HBS. High levels of preoperative intact parathyroid hormone (iPTH) were identified as a significant risk factor for HBS. A consistent postoperative calcium and vitamin D supplementation was recommended.
