The full body DEXA scan is low energy and gives a baseline of bone density and if there are lesions (generally not present in MGUS or SMM). I had early osteoporosis that was reversed to osteopenia after 3 Reclast infusions over 4.5 years; now I lift weights and other resistance training and get enough calcium (my B12 numbers are good). I am 71 and was diagnosed with MGUS 9 years ago. It has slowly ramped up over the years but numbers go up and down some. MGUS is a waiting game; it is important to take care of yourself, healthy diet, enough sleep, avoid stress (not always easy for RNs), and have things to look forward to every day. I take a gram of bioavailable curcumin supplements (from turmeric); no telling if it helps to decrease MGUS risk, but it is anti inflammatory and doesn't have side effects in me. For most people, MGUS never turns into C, but having the possibility is hard.
