Your father may have chronic kidney disease (CKD), but I am unable to make that diagnosis based on the information that you provide. In order to recommend diet and treatment, it is necessary to make a specific diagnosis as to why he has kidney disease. I suggest that you consult with a nephrologist and come to a specific diagnosis and treatment plan. Diet can be helpful, but again, must be based on a specific diagnosis as to the cause of CKD. I suggest further consultation with his nephrologist and his primary care physician (PCP). In most cases, CKD cannot be cured but rather should be managed to prevent further loss of kidney function.
