[Secondary osteoporosis and internal medicine].
BACKGROUND
The term 'primary' osteoporosis refers to osteoporosis that results from the involutional losses associated with aging and, in women, additional losses related to natural menopause. Osteoporosis that is caused or exacerbated by other disorders or medication exposures is referred to as 'secondary' osteoporosis.


BACKGROUND
This article describes the major causes and provides a framework for the diagnostic investigation of patients with suspected of having secondary osteoporosis. There are numerous causes of secondary bone loss, including endocrine disorders, disorders of the gastrointestinal or biliary tract, rheumatic diseases, haematological diseases, immobilization, adverse effects of drug therapy, and a wide miscellaneous group.


CONCLUSIONS
Secondary osteoporosis is potentially reversible during the treatment of the underlying disease. It must be identified and induce a symptomatic treatment in all cases plus an etiologic treatment when possible.
