My father's age is 67 years. He has chronic kidney disease. His creatine level is 2.1 to 2.3 since last two years. He has no diabetes or high blood pressure but the reason behind ckd is excessive use of painkillers. I'm really worried about my father please tell me can ckd stage 3 be controlled so that is won't progress to dialysis. What is the life expectancy of my father. His size of kidneys are just 30-40%.
