Correct. However, Dialysis may not be necessary if the type 2 Diabetes is no longer in effect.
It may be too late to save her kidneys.
Then again, what is the harm in trying?
If you are in ESRD brought on by a chronic condition like diabetes, the likelihood of your kidneys recovering even if you’re able to rid yourself of the underlying disorder, is miniscule.
In acute renal failure, where failure is brought on by a relatively sudden event, like a drug overdose, or physical injury, or a viral or bacterial infection, the kidneys may bounce back. Or not.
But diabetes that results in kidney disease causes chronic kidney disease, and the damage done is usually permanent.
If you have ESRD (GFR < 15), you may be able to hold off from dialysis until GFR falls into single digits, but barring a miracle, you will need dialysis.
Folks with chronic kidney disease (CKD), must keep their protein level low. I don’t know how that would affect a ketogenic diet.
People with kidney failure have trouble metabolizing proteins, a keto diet would probably put her in crisis more frequently, possibly kill her before effecting the diabetes.
