Osteoporosis is a disorder that is characterized by loss of bone mass and a structural deterioration of the bone tissue. People with osteoporosis are susceptible to fractures, especially to the wrist, hip and spine, although breaks can occur in almost any bone in the body. Spinal fractures are the most common type of osteoporotic fractures that occur, which can alter the shape and length of the spine. For some people affected by this disease, simple activities like bending over to pick up something, lifting a child or a bag of groceries, bumping into something or getting out of the shower and slipping can cause a bone to break. Osteoporosis is sometimes called a “silent” disease because an individual may not know they have osteoporosis until a fracture occurs. In fact, it is not uncommon for people to discover they have a fractured vertebra (or multiple vertebrae).
