I went to the Dr's some months ago and he sent me for some routine blood tests. The initial problem for which I was sent, turned out to be ok but what was found in my blood sample was that my kidneys are only working at 52% of their 100% potential. Of this I had no idea. No symptoms, nothing. This is classed as level 3 of kidney disease. Level 1 being excellent, level 5 being at failure. Fortunately, I have taken steps to help myself and at the last blood test, my kidneys were at 72%, which is a vast improvement.
My point is, is that we often assume that there is a long, slippery slope and years of illness before a person needs a transplant ..and that it only happens to other people. Well, it could happen to you and me, at any time and with no warning. The subject of transplantation needs to encompass the 'opt out' solution so that we may all carry on living without the added burden of 'hoping' that an organ my be free, match our bodies and not be rejected!
