Osteoporosis is a reduction in the amount of bone in the skeleton, which reduces the strength of bones and makes them more likely to break (fracture). The commonest fractures in osteoporosis are the spine, hip and wrist fractures. Osteoporosis is the commonest acquired bone disorder and cause of fractures in adults. One in two women and one in five men over the age of 50 will have a fracture due to osteoporosis.

Endocrinologists specialize in treating and preventing bone loss and preventing fractures. In addition, endocrinologists treat disorders that may affect bones, such as hyperparathyroidism, low and high levels of calcium.
