Although this is different, I had blood tests and was found to be in stage 3 of Kidney Disease. I had no idea, as the blood test was for something else!
I wasn't doing anything wrong ie, taking loads of salt, drinking loads of alcohol etc, so failed to see what I could do to help myself. The only thing I did do was take about 15 herbal tablets a day, ranging from Oil of Evening Primrose to Kelp, Co Q 10, vitamin C, etc so I just stopped taking all of them.
I have since been for 2 more blood tests and my kidney function has gone from Level 3 to Level 2 and is getting better and better. (Level 1 is excellent - Level 5 which is kidney failure)
I don't feel any worse off for not taking all my homeopathic remedies but am sure saving money!
