Osteoporosis

In osteoporosis, bones lose calcium and phosphate salts and become abnormally vulnerable to fracture. Osteoporosis may be primary or secondary to an underlying disease.

Primarily postmenopausal Primary osteoporosis most commonly develops in postmenopaus al women, although men may also develop osteoporosis. It’s called postmenopausal osteoporosis if it occurs in women ages 50 to 75 and senile osteoporosis if it occurs between ages 70 and 85. Risk factors include inadequate intake or absorption of calcium, estrogen deficiency, and sedentary lifestyle.

Osteoporosis primarily affects the weight-bearing vertebrae, ribs, femurs, and wrist bones. Vertebral and wrist fractures are common.

What causes it:

The cause of primary osteoporosis remains unknown. Secondary osteoporosis may result from:

• prolonged therapy with steroids, aluminum-containing antacids, heparin, anticonvulsants, or thyroid preparations

• total immobility or disuse of a bone (as with hemiplegia). Osteoporosis is also linked to alcohol abuse, malnutrition, malabsorption, scurvy, lactose intolerance, hyperthyroidism, osteogenesis imperfecta, and Sudeck’s atrophy (localized to hands and feet, with recurring attacks).
