My fathers age is 61 , he is having diabetes and high blood pressure from last 25 years. In August 2021 he is admitted in ICU due to pneumonia. He cured from pneumonia but as side of effect of medicine his creatinine level rised to 4 and serum urea level increased to 220. So doctor suggested for dialysis and we did, then creatinine decreased to 3.3 and urea came to 150. After that we stopped for dialysis. Now a days his creatinine level fluctuating between 3.4 to 3.9 and urea level between 60 to 90. Now doctor is suggesting that now we have to prepare for permanent dialysis or kidney transplant. So I need to know is our doctor guiding us in proper manner or not
