Hi, I have CKD but it has been stable for a long time with eGFR = 60 so borderline stage 2/3. GP doesn't believe it is due to diabetes as it has been around 60 for at least 15 years and pre-diagnosis. My records don't go back any further. I tolerate 1000mg of Metformin without issue. Fortunately, I don't have any other conditions like heart failure, hypertension etc.

eGFR is glomerular filtration rate. The 'e' means estimated from creatinine level. It measures how quickly the kidneys do the job of filtration. It is dependent on age, race and sex and weight as well.
