We all may believe we’re invincible, but this is obviously not true, especially for those who may be suffering from an illness we are unaware of. As we get older our bone mineral density (BMD) decreases, or in other words, our bone’s strength grows weaker. The reason why bones thin as we age is because the body reabsorbs existing bone cells faster than new bone is made. When this happens, the bones lose minerals, mass, and structure, making them weaker and increasing their risk of breaking. While all people begin to lose bone mass around age 30, some may start losing bone mass sooner, while other may lose it later. The time as which your bones start to thin depend heavily on your diet as well as genetics.
