Osteoporosis is a disease where bone density and quality decreases, making bones fragile and prone to fractures. It affects over 55% of people over age 50. Key factors that determine peak bone mass attained by young adulthood include heredity, physical activity, nutrition and lifestyle. While bone density scans can help assess risk, most fractures occur in those with normal or low bone density. Exercise that loads and supports the spine, like the Meeks Method, along with bracing and supplements can help prevent fractures and manage osteoporosis symptoms.
