I had some blood tests with slightly worrying renal tests. Low gfr and high potassium. Also, high ish mcv rate. There are a lot of threads about liver but not so much about the kidneys. I am quite sure this is due to fairly heavy alcohol use in the past although I am significantly better now and thinking now to stop entirely. I know the kidneys do not repair like the liver but does anyone have any positive news of these issues slowing after reducing / stopping drinking please? Thank you
