Acute Renal Failure is a sudden loss of kidney function in which the kidneys are unable to filter waste products and excess fluids from the blood effectively. This condition, also known as acute kidney injury (AKI), can develop rapidly within a few hours or days. When the kidneys fail to perform their normal functions, toxins and fluids accumulate in the body, which may lead to serious health problems.
Acute renal failure can occur due to several reasons such as severe dehydration, infections, reduced blood supply to the kidneys, certain medications, or blockage in the urinary tract like kidney stones. Common symptoms may include reduced urine output, swelling in the legs, ankles, or face, fatigue, nausea, and confusion.
Doctors usually diagnose acute renal failure through blood and urine tests that evaluate kidney function. Treatment mainly focuses on identifying and treating the underlying cause, restoring fluid balance, and providing supportive care to help the kidneys recover.
