Acute kidney injury (AKI) is a sudden and rapid decline in kidney function, usually caused by conditions such as dehydration, infection, or the use of certain medications. It is a serious medical condition that can lead to a buildup of toxins in the body and can be life-threatening if not treated promptly. The main symptoms of AKI include decreased urine output, swelling in the legs and feet, and confusion or dizziness. Treatment for AKI often involves addressing the underlying cause, such as providing IV fluids or stopping the use of harmful medications. Early detection and prompt treatment of AKI are essential in preventing long-term kidney damage and improving patient outcomes.
