My dad's heart is functioning at 30%, his kidneys are at 36% and he's diabetic. How long do you think he has? He also is stage 5 vascular dementia . Had a stroke 15 years ago, multiple heart attacks the list goes on... Right now he is also experiencing chronic angina . They cant do anything do to his health he is maxed out on heart meds. He is also on gout meds which are taxing the kidneys. His blood sugar is nuts and will hit 300 every other day if not daily. How fast are those kidneys going down?
