Acute Kidney Injury (AKI)

AKI occurs when the kidneys suddenly lose their ability to filter waste from the blood. It can develop within hours or a few days, most often within 48 hours, though in some cases it may take up to a week. Early treatment is important to prevent serious complications.

Frequently Asked Question's About AKI

What is acute kidney injury (AKI)?

Acute kidney injury is a sudden decline in kidney function that develops over a short period. It can cause waste products and excess fluid to build up in the body and may require prompt medical evaluation and treatment.

What can cause acute kidney injury?

AKI can occur because of severe dehydration, infections, low blood pressure, significant blood loss, certain medicines, urinary blockage, or direct injury to the kidneys. Sometimes several factors can contribute at the same time.

What are the warning signs of acute kidney injury?

A noticeable reduction in urine output, swelling in the legs or face, unusual tiredness, nausea, breathlessness, confusion, or sudden changes in overall health may occur. Some people may have few symptoms, so blood and urine tests can be important when AKI is suspected.

How is acute kidney injury diagnosed?

Doctors usually assess kidney function through blood tests that measure markers such as creatinine, along with urine tests and a review of recent illnesses, medicines, fluid intake, and medical history. Ultrasound or other imaging may be advised when a blockage or structural problem is suspected.

Can acute kidney injury be reversed?

In many cases, kidney function can improve when the underlying cause is identified and treated promptly. Management may include correcting dehydration, treating infections, stopping or adjusting medicines that are affecting the kidneys, relieving urinary blockage, and providing dialysis temporarily when it is medically necessary.
