Just had my annual physical and i was told that my kidneys are at 66%. All he told me so far was that once I’m at 60% Its considered low kidney function. I have a follow up appointment to discuss it with my doctor but I’m nervous and need to know now. If you don’t know, please don’t bother saying a stupid answer. I’d rather have no responses than for smart Alec answers. What could be the cause? What can i do now? Everything else came back good and i don’t have anemia.
