“Osteoporosis” literally means “porous bones.” The bones become weaker, increasing the risk of fractures, especially in the hip, spinal vertebrae, and wrist. Bone tissue is constantly being renewed, and new bone replaces old, damaged bone. In this way, the body maintains bone density and the integrity of its crystals and structure. Bone density peaks when a person is in their late 20s. After the age of around 35 years, bone starts to become weaker. As we age, bone breaks down faster than it builds. If this happens excessively, osteoporosis results.
