What could it mean if you have an over active kidney and you have copd?

.????: What is overactive kidney? Do you mean bladder? I am not aware of any association with copd. May be someone else from the doctors community answer this question.

Not related: Kidney overactivity and COPD are 2 separate medical problems which are unrelated. Obviously, the more medical problems you have, the worse your quality of life, but these are other wise not connected.
