Most physicians don’t recommend checking for bone mass until you reach your 50’s. However, habits in our modern lives such as smoking, eating disorders and lack of exercise can cause early deterioration of our bones. There are two main ways of testing for bone health: DEXA (Dual Energy X-ray Absorptiometry) and NTx (Cross-linked N-telopeptides of type I collagen).
Peak bone mass is typically reached by age 35. However, that doesn’t mean that you can’t lose bone before 35. Many younger than 35 have reported bone density below normal genetic and/or lifestyle factors. Here are the genetic factors for elevated risk of bone loss, and which ones can be reversed.
