Acute Glomerulonephritis: Causes, Symptoms, Diagnosis, and Treatment


Acute glomerulonephritis is a kidney disorder characterized by inflammation of the glomeruli, the tiny filtering units in the kidneys. It can lead to impaired kidney function and other complications. In this article, we will explore the causes, symptoms, diagnosis, and treatment options for acute glomerulonephritis, providing valuable insights into this concerning kidney condition.


Acute glomerulonephritis is an immune-mediated condition where the glomeruli, responsible for filtering blood and removing waste, become inflamed and damaged. The inflammation typically results from an overactive immune response to infections or other triggers. As a consequence, the kidneys' ability to filter waste and excess fluid is compromised, leading to potential complications like fluid retention and electrolyte imbalances.


The symptoms of acute glomerulonephritis may vary and can include:

  • Dark-colored urine due to the presence of blood
  • Foamy or frothy urine caused by excess protein
  • Swelling (edema) in the hands, feet, or face
  • High blood pressure
  • Fatigue and weakness
  • Decreased urine output
  • Abdominal pain


Acute glomerulonephritis can be caused by various factors, including:

  • Infections: Bacterial infections, such as streptococcal infections (strep throat or skin infections), are common triggers.
  • Immune system disorders: Certain immune-related conditions, like lupus or vasculitis, can lead to glomerulonephritis.
  • Other infections: Viral infections, such as HIV or hepatitis B, may also be associated with acute glomerulonephritis.
  • Medications: Some drugs, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or certain antibiotics, can cause kidney inflammation.
  • Exposure to toxins: Rarely, exposure to certain toxins can trigger glomerulonephritis.


Diagnosing acute glomerulonephritis involves a combination of medical history, physical examination, and diagnostic tests, which may include:

  • Urine analysis: A urine sample is evaluated for the presence of blood, protein, and other abnormalities.
  • Blood tests: Blood tests help assess kidney function and detect the presence of infections or immune-related markers.
  • Kidney biopsy: A small sample of kidney tissue is examined under a microscope to confirm the diagnosis and determine the underlying cause.
  • Imaging studies: Imaging tests, such as ultrasound or CT scans, can assess kidney structure and identify abnormalities.


Treatment for acute glomerulonephritis aims to control symptoms, manage complications, and address the underlying cause. Treatment options may include:

  • Antibiotics: If a bacterial infection is the cause, antibiotics are prescribed to treat the infection.
  • Corticosteroids: These medications help suppress the immune response and reduce inflammation in immune-related glomerulonephritis.
  • Immunosuppressive drugs: In certain cases, medications that suppress the immune system may be used to manage immune-related glomerulonephritis.
  • Blood pressure medications: Medications to control high blood pressure and reduce strain on the kidneys.
  • Dietary changes: Reducing salt and protein intake may be recommended to support kidney function.


Preventing acute glomerulonephritis involves prompt and appropriate treatment of infections, especially streptococcal infections, to reduce the risk of kidney complications. Additionally, managing immune-related conditions and avoiding exposure to nephrotoxic substances can help prevent glomerulonephritis.


Acute glomerulonephritis is an immune-mediated kidney disorder characterized by inflammation of the glomeruli. Early diagnosis and proper management are crucial to preserve kidney function and prevent complications. If you experience symptoms of acute glomerulonephritis or have concerns about your kidney health, seek medical attention for accurate diagnosis and personalized treatment to promote kidney well-being and overall health.
