They fluctuate according to many factors, including hydration, probably time of day (it seems), and muscle use (I was told).

My docs told me that the eGFR based on creatinine is sensitive to muscle wasting and weight loss. The Cystatin C eGFR is a better measure, I was told.

Thank you for replying first

Thought you couldn't repair kidney damage?

It's kidney disease. And yes it can improve. I have been told hydration is very important, as well as avoiding certain meds (NSAIDS). Only use tylenol. Other issues with salt, blood pressure, potassium, protein in diet etc. etc. and recommendations are different for each of us.

If you were at all dehydrated for the first test, that would make your eGFR worse. Do you have a Cystatin C done?

Your vitamin D is very low. Is your doc dealing with that?

Nut if my numbers are getting better how can other numbers be goi g the wrong way

Not sure what you mean. Maybe you can post tomorrow and explain!
