Hello! I am a 61 y.o. female and have had blood in my urine going back to 2007. An ultrasound in 2015 showed mild kidney disease. I recently had another ultrasound after another UA showed a large amount of blood in my urine. No proteinuria. I have an eGFR of 56 -Stage 3a. I’m supposed to have a CT next week. My grandfather died at age 53 from kidney failure. My father had to go on dialysis in his mid-60’s and stopped after about 4-1/2 yrs. He died at age 69. With my family history, I am curious about my prognosis pertaining to how fast I may wind up at Stage 5. I am not overweight, no diabetes or high BP. Is there any way to predict this? Thank you.

GFR 23 range for last 2 years. Watch protein intake, no dairy, exercise daily (well almost), salt intake range 1500 a day. Looking at Dr. McDougalls plant based diet. Curious as he suggests potatoes & other vegetables that are high in phospahates or potassium. Do the benefits of the plant based diet out weight the concern for potatoes etc.? My counts at this time are phosporus 4.7 mg BUN 45mg & creatinine 2.13 I’m not fond of vegetables so Dr. McDougalls diet – focused on starch as your main course – looks appealing. with bread & potatoes & think I could stay on plant based but not sure safe for CKD.

I have always encouraged a balanced diet and never focusing on a narrow list of foods. The most important part of the diet is to restrict sodium or salt intake. I suggest a limit of 2300 milligrams of sodium intake … Continue reading
