许多药物在长期服用时,会阻碍人体对某些营养素的吸收、合成、代谢、排泄过程,引起营养不良。因此,长期服药者须当心药物性营养不良。激素类药物:常用的有泼尼松、地塞米松等药物,经常服用可引起肌肉萎缩、骨质疏松等,这与营养不良有关。因为激素类药物抑制肠道吸收钙,引起血钙不足,这时甲状旁腺开始工作,结果骨质形成速度减慢,而破骨细胞的活动大大加剧,骨质被溶解,于是钙就从骨质内释放出来。 Many drugs in the long-term use, will hinder the body’s absorption of certain nutrients, synthesis, metabolism, excretion process, causing malnutrition. Therefore, long-term drug users should beware of drug-induced malnutrition. Hormones: Commonly used prednisone, dexamethasone and other drugs, often taking can cause muscle atrophy, osteoporosis, etc., which is associated with malnutrition. Because the hormone drugs inhibit the intestinal absorption of calcium, causing blood calcium deficiency, then the parathyroid began to work, the result of bone formation slowed down, and osteoclasts greatly increased activity, the bone is dissolved, so calcium from the bone Quality released.
