My father is 72 years old. He is undergoing dialysis twice a week since last 1 year. Having diabetes n taking trajenta for it. Problem is he has become too week n lost a lot of weight since dialysis started. We are giving him nephro HP powder n egg whites. Can you please tell some high protein n low potassium edibles as his potassium also remains high. N second problem is his BP remains low n during dialysis also sometimes the machine stops due to lack of flow. What can we do?
