<s>[INST] My sister was told she has stage 4 kidney failure (January 2014). The doctor told her she was 71 years old and had a good life, come back in October. I have been reading articles on Kidney failure. Will reducing protein intake and taking vitamin B1 help? What else should she do? Thanks Rick Wilson [/INST] Hi, dairy have gone through your question. I can understand your concern. She has stage 4 kidney failure. Protein metabolism and its end product increase the load on kidney. So reduction in protein intake help in kidney failure condition. Vitamin B is also helpful. Hope I have answered your question. If you have any doubts then feel free to ask me. I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
