at what stage do you start feeling nausua

I don't this it is necessarily attached to a specific stage but we do have an article about the stages of CKD and what they are about, in general if you'd like to check it out: https://chronic-kidney-disease.net/stages It may give you a place to start, if nothing else. Either way, remember, you are not alone, and if there's anything else we can do to help, let us know! Keep on keepin' on, DPM
