The cause of primary osteoporosis is unknown; however, a mild but prolonged negative calcium balance, resulting from an inadequate dietary intake of calcium, may be an important contributing factor — as may declining gonadal or adrenal function, faulty protein metabolism due to estrogen deficiency, and sedentary lifestyle. Causes of secondary osteoporosis are many: prolonged therapy with steroids or heparin, total immobilization or disuse of a bone (as with hemiplegia, for example), alcoholism, malnutrition, malabsorption, scurvy, lactose intolerance, osteogenesis imperfecta, Sudeck’s atrophy (localized to hands and feet, with recurring attacks), and endocrine disorders (hypopituitarism, acromegaly, thyrotoxicosis, long-standing diabetes mellitus, hyperthyroidism). The incidence of osteoporosis is high, with an estimated 10 million U.S. residents suffering from osteoporosis and another 18 million suffering from low bone mass, or osteopenia. Incidence is higher in women than in men, with women older than age 50 accounting for 20% of cases. Another 30% of women have osteopenia, which can deteriorate into osteoporosis.
