Prerenal acute renal failure is a type of acute kidney injury (AKI) that occurs when the kidneys do not receive enough blood flow to function properly. This can be caused by a variety of conditions, including dehydration, heart failure, sepsis, and certain medications. When the kidneys do not receive enough blood flow, they are unable to filter waste products from the blood, leading to a buildup of toxins in the body. Symptoms of prerenal acute renal failure include fatigue, confusion, nausea, and decreased urine output. Treatment typically involves restoring blood flow to the kidneys and correcting the underlying cause of the condition.
