He is hyperhosphatemic. Recently he did lose 3 pounds, and we did GI testing and an AUS, and that was all normal. The cardiologist is concerned it is from stress due to his heart (there was a time when we were having trouble controlling the arrhythmia). He is all of a sudden a very picky eater. He now will only strangely eat prescription renal diets. his internal medicine doctor is concerned about that, and the cardiologist is ok with him eating whatever. The general medicine doctor I work for is on the fence. I’m doing my own research on VIN, and am getting arguments for both sides. So I thought I’d see what folks on here had to say. In the end I’m inclined to let him eat whatever he wants as long as it isn’t doing damage. Thoughts?
