Individuals over forty years old are more likely to develop Paget's disease than others. The condition is rarely diagnosed in individuals younger than forty years old. This shows the risk of developing Paget's disease increases with age. The onset of the disorder usually occurs after fifty-five, and approximately eight percent of the population over sixty may be suffering from Paget's disease. Our bones are constantly renewing themselves, but Paget's disease causes excessive breakdown and formation of bone tissue.
Symptoms may be mild or undetectable in the beginning stages and surface in later years. They are often confused with other bone disorders like osteoporosis, another age-related bone condition, because of the similarities. Many age-related conditions cause symptoms of Paget's disease: weak bones, bone pain, deformities, and fractures.
