@jprust As mentioned, I started my dialysis at 14% eGFR. Many people don't start dialysis until they are at 10% or below, or showing critical symptoms. There are studies that show if someone starts dialysis at a higher percentage of kidney function, their body may tolerate it better, because they are not so compromised physically.

Although it may not be what your husband wants to do, I would gently suggest he consider looking into dialysis now. Don't wait. For me, it made me feel better in a very short time!
