Acute kidney disease is the sudden loss of kidney function that occurs when high levels of waste products of the body's metabolism accumulate in the blood. This occurs when the kidneys are unable to get rid of the daily toxins in the urine, which can cause serious complications. 

Some of the causes of acute kidney disease are dehydration, serious infection or sepsis, damage from some medications or toxins, a severe injury or kidney stone. Blood and urine tests, ultrasound and other tests can check the status of your kidney function. 

In many cases, the causes of acute kidney disease can be treated within a few days or weeks and kidney function will be restored. Follow-up visits and monitoring may be needed to assure that kidney failure has been resolved and preventive measures may be needed so that recurrence can be avoided.
