As you have read here, there are many more food restrictions to consider for type 2 diabetics and stage 3B. I also have a Mayo nephrologist in AZ, and I have touched Stage 4, and finally returned to Stage 3A because of medications of Torsemide on one occasion, and Farxiga on another. I watched the trends of my labs, put them into a spreadsheet with comparison of one drug and its effects on my trend. I did the same with the second drug when that was in use. Nephrologists, for some reason, think that these 2 drugs would help type 2 diabetics. For me that wasn't the case. When following dietary restrictions, please also look at your medications as a possible further cause of Stage 3B and perhaps touching Stage 4.
