人们一般将面部出现皱纹、头发变白作为衰老的象征。其实人体衰老最早的是骨组织。 医学研究证明:人在二十岁左右就开始出现骨衰老。骨衰老的表现是指骨质脱钙所致的骨丧失,严重的骨质脱钙就形成了骨质疏松症。骨丧失进程最快的是在50～70岁之间。随着年龄的增长,骨组织脱钙现象逐渐加重,致使骨质密度降低,骨皮质变薄,骨骼的韧性和弹性降低,从而形成骨质疏松症。骨丧失的骨骼最容易导致骨折,且骨折后常常不易愈合或影响关节的功能,给老年人带来极大的痛苦。
People generally face wrinkles, white hair as a symbol of aging. In fact, the oldest human body is bone tissue aging. Medical research shows that: people begin to appear bone aging at the age of twenty. The performance of bone aging refers to the loss of bone caused by decalcification of bone and the formation of osteoporosis by severe decalcification of bone. The fastest bone loss process is between 50 to 70 years old. With age, decalcification gradually increased bone tissue, resulting in decreased bone density, cortical bone thinning, bone toughness and elasticity decreased, resulting in osteoporosis. Bone loss of the bone most likely to lead to fractures, fractures and often difficult to heal or affect the function of the joints, to bring great suffering to the elderly.
