Your kidneys, like every other organ in your body, have multiple jobs. They’re deeply connected to the rest of your body. Their main function is to filter waste out of your blood.They also remove extra fluid from your blood (this becomes urine) and control blood pressure. Kidneys help make red blood cells.They regulate electrolytes (a type of nutrient) and activate vitamin D, too.
When your kidneys are damaged, they stop working as they should. This could happen because of another health condition, like diabetes. A decrease in kidney function that happens over time is called chronic kidney failure.
When your kidneys stop working suddenly, you have what doctors call acute kidney failure (or acute renal failure). It can happen over just a few hours or days.
Acute kidney failure isn’t always permanent. If you get treatment right away — and if you don’t have other serious health problems — your kidneys may go back to working like normal.
Symptoms of Acute Kidney Failure
Sometimes, there aren’t any. Your doctor may discover you have this condition while doing lab tests for another reason.
