@pcjaparis Welcome to Mayo Clinic Connect.

Chronic Kidney Disease [CKD] can be attributed to many different causes, including uncontrolled high blood pressure, diabetes, long-term medication side effects, genetic issues, and lifestyle. The high blood pressure and diabetes appear to be the leading causes, from research studies.

It is my nonmedical opinion, that we shouldn't look at a single test, but rather the trend that our routine labwork shows us. There might be a different analyzing machine used, or our hydration level may be different than another testing date, etc. These are both factors that can affect results. What have your previous lab results shown for eGFR?

As you read the posts here, you will no doubt read that many of us have experienced our doctors not seeming to be too concerned about dropping eGFR numbers. That is where it becomes important for us to be our own advocates! Knowledge is power! What other questions do you have for me?

Many doctors do not care to discuss CKD; they think there is nothing to do for it. Or they just don't think. Many are doctors just to get the money. I had CKD stage 3 for 18 years and 3 doctors or the hospital did not tell me. Moved to NC and first doctor told me I was stage 3. Scared me! I sent to former hospital in Ohio for all my records. Every test showed stage 3 CKD. My last test came in with stage 2. Must have been a change in diet: making vegetable soup with a small amount of beef for a large pot. So, I have a chicken sandwich and slaw for lunch and the veg soup for dinner. Drink 64 ounces of water - this is extremely important. I do not know about how much water for stage 4 or 5-never been there.

Because I have type 2 diabetes as well as CKD, I would think you should see an endocrinologist first because you may have pre-diabetes. Your value of 6.4 is higher than normal which may lead to CKD. @gingerw is correct in that the trend is most important for kidney function and diabetes control. The unfortunate part for me is seeing a kidney doc regularly because they are so booked for stages 4 & 5, and end stage kidney disease. I have found that many nephrologists prefer 6 month follow ups for stage 3 or earlier. Stage 3 is quite vulnerable because in my opinion it requires 3 month visits. For CKD patients, control in many cases are diet, water intake and exercise. There is so much more and this forum has much help from others in making good choices on what to eat especially like @kamama94.
