what is bone disease
Bone Disease. Bone disease is a condition that damages the skeleton and makes bones weak and prone to fractures. Weak bones are not a natural part of aging. While strong bones begin in childhood, people of all ages can improve their bone health.ow bone mass is when bones lose minerals, like calcium, that make them strong, and as a result, bones become weak and fracture easily. Fractures to weak bones typically occur from falling or other common accidents. Other bone diseases include Paget's disease and osteogenesis imperfecta.
