Osteoporosis is a disease of bone which is common in middle aged post-menopausal women. The osteoporotic bones will become weak and are prone to fractures. Osteoporosis means “porous bone” is a “silent disease”. Healthy bone microscopically appears like a honeycomb but, in osteoporotic patients the spaces are much bigger. The osteoporotic bone will have less density or mass and the structure of bone tissue is abnormal.
