<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, my father needs regular diyalysis which started recently. He was advised to do diyalysis 3 times a week but he is only doing it once a week. Can you please advice me what are the risks of not doing it 3 times? He also needs a injection erytropoetin 500ui a week Thank you  <response>: HelloThanks for query. The frequency of dialysis is decided by a Nephrologist on the basis of Serum creatinine levels and stage of renal parenchymal disease. Your father has been advised dialysis thrice a week suggest that he has grade 3-4 CKD. Reducing the frequency of dialysis will lead to raise his creatinine levels in blood and may invite many further complications and progress his CKD. I would suggest you to convince him to have the dialysis thrice a week, and it is mandatory and is in the interest of his health. Chat Doctor.
