Congestive heart failure (CHF) is a condition in which the heart's function as a pump to deliver oxygen rich blood to the body is inadequate to meet the body's needs. It can affect many organs of the bodysuch as the kidneys. The heart may not be able to supply enough blood to the kidneys, which then begin to lose their normal ability to excrete salt and water. This diminished kidney function can cause to body to retain more fluid. Treatment involves lifestyle modifications and medications prescribed by your doctor depending on the underlying causes.
Kidney failure, on the other hand, may be acute or chronic. It results from the inability of the kidneys to function. Aside from kidney transplant and dialysis, diet and medications play an important rule.
It would be best to see your doctor or be referred to a nephrologist for further evaluation and management. Take care and regards.
For anyone to answer such a question more details would have to be included. But in general the best treatment for Kidney FAILURE is dialysis or a Kidney Transplant. I have had both.
There is no cure for Kidney Failure. Maybe one day medical advancements will change that but for now the best thing is either Nocturnal or home dialysis or a Kidney Transplant which a transplant currently can last anywhere from not at all to 30+ years.
Everyone's situation is different. Seek a Nephrologist for detailed information that is specific for your own situation.
