How much do they focus on your BMI score for the Pre join medical for RN? My BMI is currently over 25 and as long as I remember it always has been. I have checked my body stats with my gym and that tells me that my fat mass is a little high but because my muscle mass is also high this is the reason my BMI is over and even if I drop the little fat I need to I will still be above the 25 BMI they are looking for. I have been reading around on this and every conclusion about BMI is that it is not representative of the individual and is not medically sound. If the Medical Dr can see I am healthy and in good shape, will I still fail due to my BMI being high or can they consider it logically and still pass me with high BMI if they confirm I am healthy and fit for service?
