@crazyelf Welcome to Mayo Clinic Connect, we're glad you found us! We are not medical professionals, and cannot diagnose, but can offer our experience and support to help you along the way! Is your husband of age for Medicare? If so, any reason why he cannot then go to a dr of his choice? Managing a proper diet with CKD is critical, and at 37% you should be watching everything. Going to the following websites may help with diet, recipes, and information
http://www.davita.com [Davita, one of two main dialysis organizations]
http://www.kidney.org [National Kidney Foundation]
http://www.rsnhope.org [Renal Support Network, an international organization]
https://www.mayoclinic.org/diseases-conditions/chronic-kidney-disease/symptoms-causes/syc-20354521 [from Mayo Clinic]

Just as an aside. Both my husband and I have kidney disease. He received a transplant Oct 2016. I am at 32% right now. But we are each responsible for our health. Your husband has to be on board with managing his own health.

Please check back in with us and let us know how things go. Will you do that? We care here at Mayo Connect.
