eGFR and creatinine changes unexplained

I can totally relate. I'm 77 and was 170lbs.
9/8 creatine 1.4 gfr 39
Started portion control diet
Feb started mediterranean diet
4/6 creatine 2.7 gfr 17
No explanation
5/29 had lost 34 lbs
Creatine 1.9 gfr 28
Again no explanation, see nephrologist in July

Good morning, thanks for your input. Best wishes for your July appointment.

@knitpurl1

you might consider a renal dietitian.

I used the online app, Nourish, to connect with a renal dietitian that has been extremely helpful and knowledgeable.

The dietitian didn’t cure me, but she did give me tools to manage the process and the various numbers that you referred to.

The Nourish dietitian is covered by insurance and his virtual.

The app itself is free and I use it on iPhone, but it can also operate an android

Thanks great advice

@kempner welcome to Mayo Clinic Connect. Diabetes and hypertension (high blood pressure) are the two most common conditions that can lead to kidney issues. It sounds like you are working hard at controlling your diabetes (weight loss, diet, monitoring A1C …). Do you monitor your blood pressure too?
I’ve been diabetic for 51 years. I have had chronic kidney disease for the past 21 years. I have an endocrinologist and a nephrologist that practice within the same healthcare system. This makes it easier for the three of us to be “on the same page” regarding my records and treatment plans.
Like you, I have experienced changes in my eGFR over time. The eGFR is affected by lots of things: diet, hydration, changes in weight, exercise, medications, other coexisting conditions, time of day you have labs done, the lab that conducts the tests…. It is best to be as consistent as possible when you get your labs done. That way you can give your provider good information so that s/he can look for trends in your condition. Before I learned this my eGFR would bounce between 14 - 42. It stabilized to the low 30’s.
Three things have also helped. One was to get my diabetes as well controlled as possible. My endocrinologist has developed a good treatment plan for me using a continual glucose monitor (CGM) and an insulin pump. The second was to get my blood pressure under good control. My nephrologist prescribes blood pressure meds and monitors that. The third thing was to learn about nutrition to plan my diet that is both diabetes friendly and kidney friendly. My providers referred me to a dietician that has training/experience in diabetes and renal disease. Being aware of how best to eat for these two conditions has helped immensely. My conditions are both stable. My A1C is 6.3 and my eGFR is 40 at present.
Who do you have for help with your diabetes?

@ca Nephrologist and Endocrinologist

Nephrologist, Endocrinologist and my primary care is great as well.
