Worldwide, it is estimated that almost 5% of postmenopausal women take glucocorticoids. As well as having specific benefits, Glucocorticoids have side effects. One of the potentially most important is that glucocorticoid use is associated with bone loss, which is most rapid in the first 3-6 months of treatment, potentially leading to serious complications and osteoporosis in many postmenopausal women.
