@like2dance2 As @windyshores mentioned, there can be a variety of reasons our eGFR drops. Dehydration, change in medications, stress levels, even different labs processing the blood samples can all play a factor. Even a medication you have been on for a while may have changed it efficacy and giving you side effects.

Push your nephrologist to find out the "why" of decreasing eGFR! I will be interested to hear what you find out.
