<p>To prepare for your DEXA scan, please do not eat (or eat very light) for four hours beforehand and be normally hydrated with water, tea, etc. Don’t over- or under-drink. &nbsp;Also, do not do any heavy exercise (eg, a gym workout or long run) for the same period. &nbsp;Please remove as much jewellery as you can before you arrive at NuMi for your scan.</p>
