I was diagnosed with sarcoidosis with high calcium levels that led to kidney damage and progressively deteriorating kidney function. Early on, I had not connected the sarcoid and hypercalcemia with the deteriorating kidney function. It was my nephrologist that made the connection. I was on prednisone for about 13 months and the sarcoid went into remission, but the damage to my kidneys had already started and continued to progress. When I began seeing a nephrologist, ckd was already at level 3b. The progression was a long, slow process and I was able to maintain level 4 ckd for years. As I got closer and closer to most likely needing dialysis, my nephrologist recommended that I have a kidney transplant which I had last year.
