My creatinine started rising in 2014. eGFR steadily getting worse. I have PKD and nephrogenic diabetes insipidus. I'm not sure if my way of eating helped me make it this far. eGFR is 26 but fluctuates. I do a time-restricted eating plan. Eat for an 8-hour period and fast for 16 hours. Just water during the fasting time. My diet is mostly vegetarian, with lots of beans, vegetables, fruit, and some sweets. Thankfully, I have an appointment at Mayo next month with a PKD specialist. My Neph locally, tells me it's all just numbers, I'll live to 100, don't worry..etc. I need more information than that. Hopefully, Drs at Mayo will provide a clear picture of what lies ahead and how to manage theses diseases.
