问:人到老年,随着机体功能的衰退,内分泌功能会发生一些变化。请先概括一下变化的特点是什么? 答:在脑下垂体的激素中,促甲状腺激素(TSH)、促肾上腺皮质激素(ACTH),和抗利尿激素(ADH)的血液水平是正常的;生长激素(GH)水平降低。所以会出现(1)损伤的修复、愈合较慢;(2)身体需要血糖升高时血糖升高不足,表现为空腹血糖偏低或于劳动及应激时血糖不能维持,易发生疲乏、衰弱、头昏等症状。绝经后的妇女促卵泡激素(FSH)增加15倍,黄体生成素(LH)增加3倍(卵巢功能衰退的一种代偿性分泌增多的表现)。男人的促性腺激素改变不明显。 老年人内分泌功能动力学试验有以下一些变化:(1)60岁以上作TSH兴奋试验——TSH上升低;(2)生长激素释放激素(GHRH)兴奋试验——GH上升较
Q: People to the elderly, with the decline of body function, endocrine function will be some changes. First, what are the characteristics of the changes? A: The blood levels of thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), and antidiuretic hormone (ADH) are normal in pituitary hormones; Hormone (GH) levels are reduced. So there will be (1) the repair of injury, healing is slow; (2) the body needs blood sugar rise insufficient blood sugar, manifested as low fasting blood glucose or stress and labor in the blood glucose can not be maintained, prone to fatigue, weakness , Dizziness and other symptoms. Postmenopausal women increased follicle-stimulating hormone (FSH) by a factor of 15, and luteinizing hormone (LH) by a factor of 3 (a manifestation of a compensatory increase in ovarian dysfunction). Man’s gonadotropin changes are not obvious. The following are some of the changes in the endocrine function kinetics test in the elderly: (1) TSH stimulation test over age 60 - TSH up low; (2) GHRH stimulation test - GH up
