Acute Kidney Injury (AKI)

Acute Kidney Injury (AKI), also known as Acute Renal Failure, is a sudden and severe decline in the kidneys' ability to filter waste products from the blood. Unlike chronic kidney disease, AKI develops rapidly, often over hours or days, and can be reversible if treated promptly. Common causes include exposure to toxins (e.g., antifreeze, certain medications, lilies for cats), severe dehydration, heatstroke, infections, or conditions that severely reduce blood flow to the kidneys. Symptoms can be sudden and dramatic, such as vomiting, lethargy, decreased or absent urination, and loss of appetite. AKI is a critical emergency requiring immediate veterinary attention and intensive care.
