Osteoporosis, or porous bone, is a disease of progressive bone loss and skeletal deterioration in which bones become fragile and more likely to break, or fracture.
The disease often develops unnoticed over many years, with no symptoms or discomfort, until a fracture occurs.
Fractures at the hip, spine, and wrist are most common, although any bone can be affected. Many of these fractures are due to a fall, however, even simple household tasks can produce a fracture of the spine if the bones have been weakened by the disease. These fractures often lead to chronic pain, disability, and reduced quality of life.
