I went to University of Michigan at Ann Arbor on Wednesday. Had a complete blood workup. On July 25 I started following "Stopping Kidney Disease" by Lee Hull. After 5 weeks I had lost 8 lbs (BMI < 19) so I had to modify diet. I went to pure vegan meaning I was having beans, lentils and other plant based sources of protein that were high in potential renal acid load.
GFR 52 (previously 40), BUN 17 (previously 28), sodium 141 (140), potassium 4.3 (4.4), creatnine 1.38 ( 1.7), Albumin 4.3 unchanged), calcium 9.7 (10.4), total protein 6.5 (7.1).
I will continue to stick to a pure vegan diet and may occasionally take albutrix if I have trouble getting enough protein. Hope this was helpful to others.
