My brother has chronic kidney disease stage 3 almost 4 and it looks like to me that hes addicted to food.  He just loves steak, pasta, processed food, etc.  He has a hard head.  Were all worried about him because we love him.  I think hes in denial and we dont know what to do.  Please help.
Hello and welcome to Chat Doctor. As a Urologist, I must assure you, that chronic kidney disease(CKD), is definitely treatable. There are so many people having similar stage of CKD, on medical treatment. He needs to follow certain guidelines very strictly, otherwise, he will deteriorate very rapidly. You can send a copy of his latest blood, urine, and scan reports, with present medication, here, in my name, for an expert opinion.
