How can heart failure lead to kidney damage or failure?

ANSWER

Your kidneys filter wastes and extra fluid out of your blood. Just like your other organs, they need a steady supply of blood to work like they should.

Without the amount of blood they need, they won’t be able to remove enough wastes from your blood. This is called kidney failure. It's treated with dialysis or a kidney transplant.

Kidney disease can also make your heart failure worse. Damaged kidneys they can't remove as much water from your blood as healthy ones. You'll start to hold onto fluid, which boosts your blood pressure. High blood pressure makes your heart work even harder.
