Dual-energy x-ray absorptiometry (DEXA) or bone densitometry, can predict and detect osteopenia and osteoporosis, conditions that often express in women and men as early as 30, in particular if there is insufficient bone formation or too much resorption or factors such as steroid use during the teens or 20’s. Physiologically, bone formation is said to peak at 30 and subsequently, there may be increase resorption and/or decrease formation in particular associated with hormonal fluctuation of menopause in women and andropause in men. DEXA bone density testing is currently the best standardized method available to diagnose osteopenia (bone thinning) osteoporosis and is also considered an accurate estimator of fracture risk.
A DEXA scan detects weak or brittle bones to help predict the odds of a future fracture and, sometimes, to determine if someone should be taking supplements (such as Vitamin D) and/or medication (such as optimizing hormones with Testosterone, Estrogen, Progesterone and/or Peptides) to slow and/or minimize or reverse bone loss. After an initial DEXA scan, subsequent scans (annually, in general) should be performed to determine whether bone density is responding to intervention. There are acceptable methods to increase bone density with extreme loss, such as medications like Prolia and Fosamax.
