Sudden ckd stage 3b egfr dropped drastically in past year, now in 1 month went from egfr of 43 to 38 creatinine 1.79 to 2.01. At the egfr 43 I took drastic measures tracking everything I ate and drank ( phosphorous, potassium, protein, calcium, etc) to guidelines for my stage, stuck with very low sodium, drink only water, approx 2000 calories a day split evenly between all meals and snacks, no red meats, chick pea organic pasta, 4oz chicken breast 1 or 2 days a week at a meal. Read every label, eat approved veggies and grains only, etc. Lost 15 lbs intentinally in 2 months (staying steady at 193lbs at 5 ft 11). I am a bit more muscular than average male. Mild exercise daily.
My type 2 diabetes is in control, last A1C is 6.9, BP stays around 101/67 or so. I test sugar every few hours as recommended all withing good ranges. My overall cholesterol is 143, my tryglicerides about 115. I am at a complete loss as to why EGFR dropped the 5 massive points in single month especially when it was not due to my diet, sugar or BP. My urine creatinine was normal at 194 mgdl. Urine protein normal at 12mgdl. Prior to this last drop my Dr switched me from metformin to glipizie and statin was atorvastatin 40mg to simvistatin 20mg. I am prone to kidney stones but these days they pass on own. Have not had one for 2 months. Still, could there be a blockage of sorts causing acute damage? No true symptoms though... Bun creatinine ratio dropped from 16 to 13, whis IS good. I have trace of ketones but could be because I decreased water intake.
My primary care doctor could care less, only says test again in 3 months for past year. Not proactive so on own scheduled nephrology appt but have had a hell of a time getting in as new patient. They postponed me several times to Oct 15! Found another neph practice who can see me next week. Very concerned of extreme decreases in EGFR and creatinine rise! Thoughts VERY welcome. We are a mess over this.
