Acute Kidney Injury
Acute Kidney Injury
Acute kidney injury is characterised by a sudden loss of kidney function, leading to a build-up of waste products and causing electrolyte and fluid imbalances. Acute kidney injury causes include dehydration, severe infections, reduced blood flow to the kidneys, certain medications, and urinary tract obstruction. Early diagnosis and treatment can help reduce the risk of permanent kidney damage. Manipal Hospitals provides comprehensive and personalised care for patients with acute kidney injury.

Request a CallbackSymptoms of Acute Kidney Injury
Acute kidney injury symptoms may include reduced urine output, swelling of the legs or face, fatigue, nausea, confusion, and shortness of breath. In some individuals, symptoms may develop gradually but still require prompt medical evaluation.
How We Diagnose Acute Kidney Injury
Acute kidney injury diagnosis involves reviewing the patient’s medical history, performing a physical examination, and conducting laboratory tests. Blood tests assess kidney function by measuring urea and creatinine levels, while urine tests help identify abnormalities in urine composition. Doctors may also recommend imaging studies such as ultrasound or CT scans to detect urinary obstruction or structural abnormalities affecting the kidneys.
Treatment Options
The primary focus of acute kidney injury treatment is to correct the underlying cause and restore kidney function. Management may include fluid therapy, medications to control electrolyte imbalances, treatment of infections, and discontinuation of nephrotoxic medications. In severe cases, temporary dialysis may be required.
What to Expect
At Manipal Hospitals, patients diagnosed with acute kidney injury undergo prompt medical evaluation to determine the severity of kidney dysfunction and identify the underlying cause. Early diagnosis allows specialists to begin an individualised treatment plan aimed at preventing further kidney damage.
Initial management focuses on stabilising the patient and treating conditions such as dehydration, infection, or reduced blood circulation to the kidneys. The care team closely monitors vital signs, fluid balance, and laboratory parameters throughout treatment.
Treatment is guided by the underlying cause and may include intravenous fluids, antibiotics for infection, blood pressure management, and careful adjustment of medications that may affect kidney health. Patients may also receive treatment to correct electrolyte imbalances involving sodium and potassium levels.
In severe cases, temporary dialysis may be recommended when the kidneys cannot effectively remove waste products from the body. Many patients experience improvement once the underlying condition is identified and treated. Regular follow-up and monitoring help assess recovery and reduce the risk of long-term kidney complications.

FAQs
-
What are the common causes of acute kidney injury?
Acute kidney injury causes include severe dehydration, infections, reduced blood flow to the kidneys, certain medications, and urinary tract obstruction. Complications following major surgery may also contribute to the condition. These factors can suddenly impair kidney function and require timely medical treatment.
-
Is it possible to reverse acute kidney injury?
Yes. In some patients, kidney function may recover completely when the underlying cause is identified and treated promptly. However, severe or prolonged injury can lead to permanent kidney damage or progression to chronic kidney disease.
-
When is dialysis required in acute kidney injury?
Doctors may recommend dialysis when the kidneys cannot effectively remove waste products, excess fluid, or electrolytes from the body. This treatment is usually temporary and supports the body until kidney function improves.
-
Who is at a higher risk of developing acute kidney injury?
People with conditions such as diabetes, hypertension, heart disease, or pre-existing kidney disease are at higher risk of developing acute kidney injury. Elderly individuals, critically ill patients, and those taking certain medications may also be more vulnerable.
-
Can some medications cause acute kidney injury?
Certain medications, including non-steroidal anti-inflammatory drugs, some antibiotics, and contrast agents used during imaging procedures, may affect kidney function. These medications can pose a greater risk in individuals with pre-existing kidney disease.
