Osteoporosis develops when the bone mineral density reduces to very low levels. It is more common among post menopausal women, and men above the age of 50 years old. It increases the risk of a fragility (low impact) fracture and you might not know you have osteoporosis until you develop a fracture. People with certain long term conditions requiring certain medications like long term steroids also have an increased risk of osteoporosis.
