56岁的赵女士近日去医院进行骨密度检查,不料结果提示她患有骨质疏松症。赵女士感到十分困 惑:"我天天都吃钙片,怎么还会得骨质疏松呢?" 赵女士的情况并非个例——许多人长期补钙,却依然被骨质疏松困扰。针对这一现象,北京大学第一医 院内分泌内科主任医师姚军作出解读。 骨质疏松症只是"缺钙"吗? 记者:什么是骨质疏松症?它是"缺钙"那么简单吗?目前骨质疏松症在我国的发病情况如何?主要影响 哪些人群? 姚军:老百姓存在一个挺大的误区——很多人一提到骨质疏松就认为是"缺钙",其实并非如此。 骨质疏松是由于骨矿含量与骨质量下降,共同导致骨骼的强度降低、脆性增加,从而使骨折风险升高的 全身性骨骼疾病。 (2)影响骨代谢的疾病,包括性腺功能减退症、糖尿病、甲状腺功能亢进症等多种内分泌系统疾病;风 湿免疫性疾病、胃肠道疾病、血液系统疾病、神经肌肉疾病、慢性肝肾疾病及心肺疾病等。 (3)影响骨代谢的药物,包括糖皮质激素、质子泵抑制剂、抗癫痫药物、芳香化酶抑制剂、促性腺激素 释放激素类似物、抗病毒药物、噻唑烷二酮类药物和过量甲状腺激素等。 补钙为何必须搭配维生素D? 记者:生活中,有人天天补钙,为什么还会得骨质疏松? 我们可以用盖 ...

人民日报海外版记者 王美华 56岁的赵女士近日去医院进行骨密度检查,不料结果提示她患有骨质疏松症。赵女士感到十分困 惑:"我天天都吃钙片,怎么还会得骨质疏松呢?" 赵女士的情况并非个例——许多人长期补钙,却依然被骨质疏松困扰。针对这一现象,北京大学第一医 院内分泌内科主任医师姚军作出解读。 骨质疏松症只是"缺钙"吗? 记者:有哪些关键的危险因素会加速骨质疏松的发生? 姚军:骨质疏松症危险因素可分为不可控因素和可控因素。 不可控因素包括年龄增长、女性绝经、脆性骨折家族史等。 可控因素主要包括以下几类: 记者:什么是骨质疏松症?它是"缺钙"那么简单吗?目前骨质疏松症在我国的发病情况如何?主要影响 哪些人群? (1)不健康生活方式,包括体力活动少、阳光照射不足、吸烟、过量饮酒、钙和/或维生素D缺乏、过 量饮用含咖啡因的饮料、营养失衡、蛋白质摄入过多或不足、高钠饮食、体质量过低等。 姚军:老百姓存在一个挺大的误区——很多人一提到骨质疏松就认为是"缺钙",其实并非如此。 骨质疏松是由于骨矿含量与骨质量下降,共同导致骨骼的强度降低、脆性增加,从而使骨折风险升高的 全身性骨骼疾病。 (2)影响骨代谢的疾病,包括性腺功能减退 ...

Core Insights - Osteoporosis is a silent condition where bone loss exceeds bone formation, leading to increased fracture risk, particularly hip fractures which have a mortality rate exceeding 20% within a year after occurrence [1][8] Group 1: Early Signs of Osteoporosis - **Sign 1: Unexplained Back Pain and Height Loss** Persistent back pain and noticeable height reduction (over 3 cm) can indicate vertebral compression fractures due to bone loss [3][4] - **Sign 2: Loose Teeth and Alveolar Bone Loss** Weakening of the alveolar bone can lead to loose teeth and gum recession, signaling potential systemic bone density issues [4] - **Sign 3: Fragile Bones** Fragile fractures occurring from minimal trauma, known as "fragility fractures," are a direct consequence of osteoporosis [6][8] - **Sign 4: Muscle Weakness and Cramps** Osteoporosis often accompanies sarcopenia, leading to decreased muscle strength and increased fall risk [9] - **Sign 5: Brittle Nails** Changes in nail health, such as increased brittleness, may reflect underlying calcium and collagen loss [10] Group 2: Prevention and Management Strategies - **Nutrition** Adequate calcium intake is crucial, with recommendations of 1000 mg daily for adults and 1200 mg for older adults. Foods rich in calcium include dairy products, tofu, and leafy greens [13] Vitamin D is essential for calcium absorption, with a daily requirement of 800-1000 IU [14] Sufficient protein intake is necessary for bone matrix formation, with recommendations of 1.0-1.2 g/kg body weight [15] - **Exercise** Weight-bearing exercises, such as brisk walking, are recommended to stimulate bone strength. Resistance training and balance exercises are also critical for preventing falls [17][18][20] - **Lifestyle Modifications** Avoiding smoking and excessive alcohol consumption, as well as reducing caffeine and carbonated drink intake, can help maintain bone health [24][25][26] Ensuring a safe living environment to prevent falls is also essential [27]
