Hidden dangers for the slim

I have grown old - unavoidable. i have not grown fat over the years - avoidable. What interests me is how I am being put at relative risk as well as inconvenience by the latter.  2 examples in health care. 1) For x-rays the standard exposure means an overdiagnosis of bone thinning. This led to bone densitometry - with the verdict that bones better than average for age. 2) For some drugs the dose is administered depending on the eGFR but this test seems very poorly understood and bodyweight is a crucial part of it. The problem is that the lab value is based on a weight I have never achieved even at my heaviest and my true eGFR is significantly lower than the value on the report. (Of course for most eGFR values it does not matter as the trend is what is significant). The second adds to my recent experiences of a long standing hobby horse that many of those requesting tests do not know how to interpret the results...... Someone pointed out recently that having CT facilities for the markedly overweight might well mean more irradiation for the not so fat. Outside medical care I am increasingly aware of being disadvantaged by being what was seen as normal weight in times gone by as the UK at least caters more and more for the obese. I suppose the answer is that if I don't like it I should add to the number and put on a few stone?
