The kidneys perform the vital job of filtering waste and balancing essential fluids in the body. When they suddenly lose this ability, the result is acute kidney injury (AKI). This condition develops rapidly, often within hours or days, and can be life-threatening if not addressed quickly. At Greer Nephrology in Greer, SC, our experienced nephrologists specialize in diagnosing, managing, and treating acute kidney injury to help patients recover kidney function and avoid long-term complications.
Understanding Acute Kidney Injury
Acute kidney injury, also known as acute renal failure, occurs when the kidneys abruptly stop functioning properly. Unlike chronic kidney disease, which progresses over time, AKI appears suddenly and can be reversed with timely treatment. The condition leads to the accumulation of waste products in the blood and disrupts the body’s fluid and electrolyte balance.
While AKI can occur in anyone, it is especially common among hospitalized patients, particularly those in intensive care. Early detection and intervention are essential to preventing further kidney damage and improving outcomes.
Major Causes of Acute Kidney Injury
Acute kidney injury has several possible causes, generally categorized into three groups:
- Pre-renal causes – These involve decreased blood flow to the kidneys due to conditions such as dehydration, severe infection, heart failure, or major blood loss.
- Intrinsic causes – These occur when the kidney tissue itself becomes damaged, often from infections, inflammation, medications, or exposure to toxins.
- Post-renal causes – These arise when urine flow is blocked, leading to a backup of pressure in the kidneys. Common reasons include kidney stones, prostate enlargement, or tumors.
Understanding the root cause is the first step toward effective treatment and recovery.
Recognizing the Warning Signs
In its early stages, acute kidney injury may go unnoticed. However, as the condition progresses, symptoms can become more apparent. These may include:
- Reduced urine output
- Swelling in legs, ankles, or around the eyes
- Shortness of breath
- Persistent nausea and vomiting
- Confusion or fatigue
- Chest discomfort
- Irregular heartbeat
Because AKI can develop quickly, it’s important to seek immediate medical attention if any of these symptoms occur, particularly after major illness, surgery, or dehydration.
Who Is at Risk?
Some individuals have a higher likelihood of developing acute kidney injury, including those who:
- Have chronic diseases like diabetes or hypertension
- Are over the age of 60
- Use medications that can stress the kidneys
- Have recently undergone surgery or medical procedures involving contrast dyes
- Experience severe infections or dehydration
Awareness of these risk factors can help patients take preventive steps and allow for faster intervention when needed.
How Acute Kidney Injury Is Diagnosed
At Greer Nephrology, diagnosis begins with a detailed medical evaluation and laboratory testing. Our nephrology team performs:
- Blood tests to measure waste levels, including creatinine and urea
- Urine tests to check for abnormalities such as protein, blood, or infection
- Imaging studies like ultrasound or CT scans to look for obstructions or kidney swelling
- Physical examination to assess fluid retention and overall health
These assessments allow our nephrologists to identify the type and severity of kidney injury and develop a targeted treatment plan.
Treatment Options at Greer Nephrology
The goal of treatment is to restore normal kidney function, manage symptoms, and address the underlying cause. At Greer Nephrology, we take a patient-centered approach that combines advanced medical care with personalized attention.
- Fluid and electrolyte management
- Patients may receive IV fluids to restore hydration or medications to balance electrolytes. For those with fluid overload, diuretics are often prescribed.
- Medication adjustments
- Certain medications can worsen kidney function. Our nephrologists carefully evaluate each patient’s prescriptions and modify them as needed to ensure kidney safety.
- Treatment of underlying causes
- Infections, heart failure, or urinary blockages are treated promptly to prevent ongoing damage.
- Dialysis therapy
- For severe cases, temporary dialysis may be required to remove waste and excess fluid from the blood while the kidneys recover.
- Ongoing monitoring and follow-up
- After initial treatment, patients are closely monitored to track progress and prevent recurrence. Our team continues to provide guidance for long-term kidney health and maintenance.
The Recovery Process
Recovery from acute kidney injury varies depending on its severity and underlying cause. Many patients regain full kidney function within a few weeks, especially with early treatment. Others may experience a slower recovery and require continued care to support kidney performance.
At Greer Nephrology, we emphasize recovery through regular follow-ups, nutritional counseling, and patient education. Our nephrologists create personalized recovery plans that help patients rebuild their strength and maintain optimal kidney health for the future.
Preventing Acute Kidney Injury
While not all cases can be avoided, several lifestyle and health management practices can significantly reduce the risk of acute kidney injury:
- Stay well-hydrated, especially during illness or hot weather
- Avoid excessive use of pain relievers such as ibuprofen and naproxen
- Manage chronic conditions like diabetes and hypertension
- Limit alcohol consumption and avoid smoking
- Monitor kidney function if taking long-term medications
- Seek medical attention promptly if experiencing signs of infection or dehydration
Taking proactive measures and maintaining routine health checkups are key to prevention and early detection.
