The decline in my kidney function has been tracked by blood tests since I was diagnosed in 2003. At that time I had 75% of my kidneys left. This was below normal for a man of my age. Over the period between then and 2012 there was more or less a straight line decline towards 25%

Thats just short of 6% per year. The treatment was to keep my blood pressure low so it didn’t force too much IGA through my kidneys. This was managed at Bradford first but their system was poor as they often didn’t get my blood results in time or were working on results 3 months old. The blood pressure management was not rigorous. 2% drop per visit didn’t seem a big deal.
More recently I have been managed by Calderdale via Leeds. Blood tests were done just before each consultation and responses rapid. My kidney function got to 25% and I stopped working at the end of June 2012. I started the 5:2 diet in October of that year and also regular acupuncture. My kidney function stabilised at around 20% (average of 19.6 over the last 12 results).
I was originally scheduled to start dyalisis in October 2012, so I have nearly bought 4 years in time so far.
