Acute Kidney Injury

📖What is Acute Kidney Injury?

Acute kidney injury is a sudden decline in kidney function occurring over hours to days, resulting in the buildup of waste products and disruption of the body's fluid and electrolyte balance. Unlike chronic kidney disease, which develops gradually, acute kidney injury arises abruptly, often triggered by a serious illness, severe dehydration, blocked urine flow, or exposure to certain medications or toxins that directly harm the kidneys. It is commonly seen in hospitalised patients, particularly those who are critically ill, undergoing major surgery, or experiencing severe infection, though it can also occur in otherwise healthy individuals from severe dehydration or an obstructing kidney stone. With prompt identification and treatment of the underlying cause, kidney function often recovers substantially, though severe or prolonged episodes can sometimes lead to lasting kidney damage. Close monitoring of kidney function is essential in anyone at risk, particularly during severe illness or after exposure to potentially harmful medications.
