[Osteoporosis associated with endocrine dysfunctions or metabolic disorders].

Secondary osteoporosis may be associated with a number of endocrine dysfunctions and metabolic disorders. In this paper, osteoporosis in patients with Cushing's syndrome, hyperthyroidism, primary hyperparathyroidism, acromegaly, hypogonadism and some metabolic disorders such as diabetes mellitus, chronic renal failure and malabsorption syndrome are described. While the major manifestation of bone in these conditions is a reduction of bone mass and may be somewhat different from bone loss in primary osteoporosis histologically or radiologically, it is considered to be the same bone loss as primary osteoporosis in the present paper. In some conditions, for example, Cushing's syndrome, diabetes mellitus etc, factors responsible for bone loss are demonstrated.
