A relative on mine is CKD Stage 5.  He is 70 year old male and is going for dialysis thrice a week for 4 hours.   His serum levels keep fluctuating now and then.  Is it due to eating food in restaurants cause of high serum levels. Below are the test results -BiochemistryBlood Urea, Serum - 106 Creatinine, Serum - 11phosphorus, serum 7.5 EnzymesSGOT (AST), serum - 45SGPT (ALT), serum - 12Haemoglobin - 11.8How serious levels are these.  Is it a cause of concern?  What is a life expectancy for this age.Please Advise,Rakesh
Dear Mr Rakesh, Serum creatinine levels may very in dialysis patients. Diet has significant role in variations. High protein diet specially meat raises serum creatinine level in kidney disease patients. Phosphorus level again depends upon diet. He needs to follow strict dietary control as advised by your treating nephrologist. All the best.
