GFR dropped 5 more points and I don't know why.

Try intermittent fasting. Fast until between 12 and 1 daily.
Check a book. The Oldest Cure in the World by Steve Hendricks.

You can find a bunch of interviews on Youtube.

Re excercise. I believe it is super important. For me at 72 this year I've always gone to gym 3 days per week. I've been retired for a while now and can spend 45 minutes each am doing stretches and bands and other low to medium impact exercise to go along with a well disciplined diet system to keep my ckd 3a stable for the long run.

I had a similar drop recently though my GFR is lower at Stage 3B. My nephrologist thinks it may be hydration. Try drinking more, specifically water. I like the exercise routine. I am at 6 days a week. Keep up the exercise and perhaps do a retest in a week to see if it is just a fluctuation.

My GFR dropped dramatically when I was put on Bactrim. It’s now on my allergy list …it did improve once I was off of it.

Mine fluctuates between stage 3a, 3b, and twice fell into stage 4. Make sure the lab is using the race neutral calculator (preferably one that adds Cystatin C). The biggest factors are fluid intake and protein consumption. Some studies show higher animal protein 3dsys prior can help increase the creatinine part, and the earlier in the say the more dehydrated I am ( at least for me)

Hi All!
I’m so glad I found you and so glad your hear

@nayanna Welcome to Mayo Clinic Connect! We're glad you are here, also! Do you have kidney disease? Tell us more about you!

Mine dropped 19 points since last August, and 6 points in last two weeks.

Creatinine is 1.5
Glucose 153
Potassium 3.4

@reecie1950 Welcome to Mayo Clinic Connect. Have you sought the care of a nephrologist [kidney care specialist] yet? Decreases in eGFR can be caused by kidney disease brought on by the two main causes of high blood pressure and diabetes, or factors like genetic tendencies, lifestyle choices, etc. Basically, doctors will look at trends rather than a specific lab result, unless there is an acute situation. Also, hydration can play a big part in the test results, as can a different in the actual laboratory/equipment used to process the samples.
