Your bones change constantly, with new bone being built and old bone being removed throughout your lifespan. Approximately every 7 years, you will have new bones! Ages 9-14 are the most important for developing your skeleton. During the teen years, you will build more bone than you will lose during your entire lifetime. You will continue to build bone in your 20s until you achieve peak bone mass around ages 30-35. Around age 35, you will slowly begin to lose more bone than you build, so it’s important to focus on healthy habits to maintain your peak bone mass. This is also a good time to be aware of risk factors, such as lifestyle habits, medical conditions and medicines, in addition to age, that can cause bone loss and increase risk of fractures. Around age 50, most women will begin menopause. Women lose up to 25% of their bone mass as their estrogen levels drop during menopause. Their risk of fractures increases in the decades following menopause. Men begin losing testosterone around age 70, which also causes a loss of bone mass, and their risk of fractures increases at the same rate as women that age.
Getting older is a major risk factor for developing osteoporosis and having broken bones. After age 50, 1-in-2 women and 1-in-4 men in the U.S. will have a fracture related to osteoporosis.
