I can not go to a nephrologist until stage 4 in Canada,our government medical does not allow it. I see a dietitian for free in 3 weeks at my local hospital. I am 54 and 2 years a go my kidney function was 92%, 4 months a go 70%, 3 months a go 70%. It is considered a problem to change so fast and I am arranging to get some blood tests on this. It is considered a problem if it changes 10% a year, even if in the normal range. I have 3 blood clots in one lung, 3 months a go found out my kidneys are not producing the hormone that makes hemoglobin and was given a hormone replacement shot and Iron pills. My blood tests showed white and red blood cells were both damaged,wrong shape and size and not enough of both. I am on Xarelto for 3 blood clots in one lung from 3 months a go and will arrange on my own for blood tests to see if improved. I was told to add salt daily to keep my blood pressure at 96/65 otherwise it is 80/60 daily and 120 with no exercise for 3 days and immediately down after my gym class. If I exercise daily blood pressure is the same before and after exercise. Maybe it is all kidney related.??
