维生素D缺乏对骨骼肌肉系统的影响

摘要

维生素D是人体不可缺少的一种脂溶性维生素,主要功能是促进肠道对钙、磷的吸收.维生素D缺乏会引起继发性甲状旁腺功能亢进,骨转化加快,骨丢失增加,从而引起骨软化、骨质疏松、骨折.另外维生素D缺乏与肌无力、活动能力下降相关,使患者跌倒发生率增加.科学有效的补充维生素D,不但能够防止由于钙、磷吸收障碍所导致的骨质疏松及骨折的发生,还能有效防止多种骨骼肌肉系统疾病.%Vitamin D is an essential fat soluble vitamin and its main function is to promote calcium andrnphosphorus absorption in the gut. Vitamin D deficiency can cause secondary hyperparathyroidism , acceleraternbone turnover, and increase bone loss, eventually lead to osteomalacia, osteoporosis, and fracture.rnAdditionally, vitamin D deficiency is associated with muscle weakness and decreased activity, leading to anrnincreased incidence of falls. Scientific and effective supplementation of vitamin D can not only preventrnosteoporosis and fractures caused by calcium and phosphorus malabsorption , but also effectively prevent arnvariety of musculoskeletal diseases.
