很多人将骨骼老化看作衰老的必然结果，却不知道骨质疏松症是一种常见且可预防的慢性骨骼疾病。它不同于短暂的肌肉酸痛、关节劳损，常年隐匿发展，有着 “沉默的杀手” 之称，严重威胁着中老年人乃至部分年轻人的骨骼健康。读懂骨质疏松症，是守护骨骼健康的第一步。
Many people regard bone loss as an inevitable consequence of aging, ignoring that osteoporosis is a common, preventable chronic skeletal disease. Unlike temporary muscle soreness or joint fatigue, osteoporosis develops silently over years, earning it the terrifying nickname “the silent killer”. It threatens the bone health of middle‑aged and elderly people and even some young adults. Understanding this disease is the first step to protecting our bones.
从医学定义来讲，骨质疏松症是一种以骨量低下、骨组织微结构破坏为特征的全身性骨骼疾病。通俗来说，健康人体的骨骼致密坚硬，内部结构如同紧实的海绵；而骨质疏松的骨骼会流失大量钙质与骨基质，变得孔隙增多、质地疏松、脆弱易碎。骨骼密度大幅下降，承重、抗冲击能力显著减弱。
Medically, osteoporosis is defined as a systemic skeletal disorder characterized by low bone mass and deterioration of bone tissue microarchitecture. Simply put, healthy human bones are dense and sturdy, with a tight internal structure like solid sponge. In contrast, osteoporotic bones lose calcium and bone matrix, becoming porous, brittle and fragile. The bone density drops significantly, and the bearing capacity and impact resistance of bones decrease sharply.
骨质疏松的发病核心是骨骼代谢失衡。人体骨骼终生处于骨吸收、骨形成的动态循环中，青少年及青年时期，骨形成大于骨吸收，骨量持续累积，在 30 岁左右达到峰值。此后骨骼代谢能力逐步衰退，骨流失速度超过骨生成速度，骨量逐年减少。女性绝经后雌激素骤降，会加速骨质流失，是骨质疏松的高发人群。除此之外，年龄增长、钙和维生素 D 摄入不足、长期久坐不动、过量饮酒吸烟等，都是诱发骨质疏松的重要因素。
The occurrence of osteoporosis stems from the imbalance of bone metabolism. Human bones are in a dynamic cycle of bone resorption and bone formation throughout life. In adolescence and young adulthood, bone formation is stronger than resorption, and bone mass gradually accumulates and peaks around the age of 30. After that, bone metabolism gradually weakens, and bone loss begins to exceed bone formation. For women, the rapid decline of estrogen after menopause accelerates bone loss, making them a high‑risk group. In addition, aging, insufficient calcium and vitamin D intake, long‑term sedentary lifestyle, excessive drinking and smoking will also induce osteoporosis.
骨质疏松最大的危害是隐匿性的脆性骨折。疾病早期，多数患者无明显不适，仅偶尔出现轻微腰酸、乏力，极易被忽视。随着骨量持续流失，患者会出现持续性腰背疼痛、驼背、身高变矮、脊柱变形等问题。病情严重时，咳嗽、弯腰、行走等日常轻微动作都可能引发骨折。骨质疏松引发的髋部、脊柱、手腕骨折，不仅会带来剧烈疼痛、行动受限，还可能导致患者长期卧床、诱发感染等并发症，严重降低生活质量，甚至危及生命。
The biggest hazard of osteoporosis is hidden fragility fractures. In the early stage, most patients have no obvious symptoms, only occasional mild back pain and fatigue, which are easy to be ignored. With the continuous loss of bone mass, patients will suffer from persistent lumbago and back pain, hunchback, height reduction and spinal deformation. In severe cases, minor daily actions such as coughing, bending over and walking may cause fractures. Hip fractures, vertebral fractures and wrist fractures caused by osteoporosis will not only bring severe pain and limited movement, but also lead to long‑term bedridden, infection and other complications, seriously affecting the quality of life and even endangering life safety.
幸运的是，骨质疏松症可防可控。青少年和青壮年可通过均衡饮食、规律运动、多晒太阳，积攒充足的骨骼储备；中老年人定期检测骨密度，科学补充钙质和维生素 D，坚持适度有氧运动与力量训练，纠正不良生活习惯，就能有效延缓骨质流失。
Fortunately, osteoporosis is a preventable and controllable disease. We can build sufficient bone reserve in youth through balanced diet, regular exercise and sun exposure. Middle‑aged and elderly people can regularly detect bone density, supplement calcium and vitamin D scientifically, adhere to moderate aerobic exercise and strength training, and correct bad living habits to delay bone loss.
骨骼健康贯穿一生。认清骨质疏松症，摒弃 “不痛即无病” 的误区，坚持科学养骨，才能让我们在各个年龄段都远离骨骼隐患，守护骨骼强健。
Bone health runs through the whole life. Recognizing osteoporosis, abandoning the misunderstanding of “no pain, no disease”, and adhering to scientific bone maintenance can help us stay away from the “silent bone killer” and maintain strong bones at all ages.
