老年脑梗塞患者,由于经常不活动,结果晨尿排钙量增加,从而发生骨质疏松症。一般认为脑梗塞多见于老年人,而骨质疏松症以老年女性为多。骨质疏松症的发生原因,目前尚不十分清楚,可能与性激素分泌减少,甲状旁腺素引起的骨质脱钙,降血钙素减少,维生素D缺乏等各种因素有关。因为不能活动,脑梗塞病人的骨质疏松症进展较快,加上缺乏日照而发生的维生素D减少,更加重了骨病变。老年骨质疏松患者,肠道吸收钙的功能也减退,全身 Elderly patients with cerebral infarction, due to frequent inactivity, as a result of morning urine increased calcium discharge, resulting in osteoporosis. It is generally believed that cerebral infarction is more common in the elderly, while osteoporosis is more often seen in older women. The causes of osteoporosis, is not yet very clear, may be related to reduced secretion of sex hormones, parathyroid hormone-induced decalcification, decreased calcitonin, vitamin D deficiency and other factors. Because of inactivity, progress of osteoporosis in patients with cerebral infarction is rapid, coupled with a decrease in vitamin D in the absence of sunshine, further aggravating bone lesions. Elderly patients with osteoporosis, intestinal absorption of calcium function also decreased, the whole body
