骨骼是不断自我更新的组织,周而复始地被破骨细胞破坏产生孔穴,成骨细胞跟着制造新骨修补孔穴。在骨量峰值形成之前,即骨骼生长发育期,成骨细胞所造的骨组织比破骨细胞毁坏的要多,从而使骨骼的体积不断增大,强度逐渐增加。但骨量峰值一过,骨骼组织的再生速度便落后于破损速度,骨质逐渐流失。 澳大利亚的研究者提出,骨质疏松症是一种起源于人生最初二十年的疾病。在骨骼的生长发育期,任何影响骨骼生长和矿物质增加的危险因素(如钙、磷和维生素D及营养缺乏,日
Bones are a constantly self-renewing tissue that is repeatedly destroyed by osteoclasts to produce holes that osteoblasts follow to create new bone repair holes. Before the formation of peak bone mass, that is, during the growth and development of bone, the bone tissue made by osteoblasts is more destroyed than the osteoclasts, so that the volume of the bone is continuously increased and the intensity is gradually increased. However, once the peak bone mass, bone tissue regeneration rate lags behind the speed of damage, bone loss gradually. Australian researchers propose that osteoporosis is a disease that has its roots in the first two decades of life. In the growth and development of bones, any risk factors that affect bone growth and mineral content (such as calcium, phosphorus and vitamin D and nutritional deficiencies,
