For the last 12 months I have been trying to improve my GFR/creatinine by reducing protein and eating only plant protein, 12 months ago my GFR was 48 and up to this latest result it has been in the mid 40's range. Everything apart from creatinine has been bang in the middle of normal. I'm a 73 year old male with multiple sclerosis in the UK, I had an ultra sound scan in the early days which was normal, and my urine sample was normal.
As my surgery weren't doing normal blood tests because of the Covid crisis, I decided to have a blood test through a private lab, this was done through the post, they only tested creatinine and urea. Urea was normal at 6.7 mmol/L and creatinine was 188 umol/L, from this they gave a GFR of 31.
So I'm a bit worried and not sure what to do next, I think I can get another blood test through the surgery if my GP recommends it, so I have emailed him asking for a phone appointment.
I have raised blood pressure and currently take:
amlodopine - 5mg x 1 morning, candesartan - 32mg x 1 morning, bisopropol - 2.5mg x 1 morning, doxazosin - 1mg x 1 evening
I wonder if any of these are causing my kidneys problems, but couldn't find anything online.
So would appreciate any help or input from the excellent people on this forum!
