Dear Doctor, My father is 83 years old, and is having S. Creatinine as 3.71. He has been having kidney problem since 1983 and during that time, it was told that his kidney is working 50%..... Now for last few days he has not been having appetitie, we have consulted doctors, few of them suggest dialisys, when many others say do not disturb him at this age. We are confused, as if we start dialysis , this doctor says, it will have to be continued twice a week and will be life long.... The report also says his sodium level is just below normal, and we can give a normal salt diet . Till these many days, he was under salt controlled diet. Can you please help
