Osteoporosis is the Loss of Bone Density

Osteoporosis is the loss of bone density caused by excessive absorption of calcium and phosphorus from the bone, due to progressive loss of the protein matrix of bone which normally carries the calcium deposits. Bones become brittle and liable to fracture. Osteoporosis is associated with ageing in both men and women. Osteoporosis is common in the elderly, and in women often follows the menopause. It is common cause of fractures, particularly fractures of the wrist, crush fractures of the spine and neck of femur fractures. It is also a feature of Cushing’s disease and prolonged steroid therapy.
