Acute Kidney Injury (AKI), also known as acute renal failure, is a sudden and rapid loss of kidney function that occurs over hours or days. It leads to a build up of waste products, fluid retention, and imbalances in electrolytes, which can become life-threatening if not treated promptly. AKI may result from various causes such as dehydration, severe infections, certain medications, or obstruction in the urinary tract.

Common symptoms of AKI include a noticeable decrease in urine output, swelling in the legs, ankles, or around the eyes, persistent fatigue or confusion, episodes of nausea or vomiting, and shortness of breath. Prompt diagnosis and medical attention are essential for effective treatment and recovery.
