Understanding

What is Post-Infectious Glomerulonephritis?

Post-Infectious Glomerulonephritis occurs when the body's immune response to an infection causes inflammation in the kidneys.

Immune complexes formed during infection get deposited in the glomeruli, affecting their ability to filter blood properly.

This condition is more common in children but can also affect adults.

Warning Signs

Early Signs & Symptoms

Symptoms typically appear 1–3 weeks after infection:

Blood in urine (tea-colored or reddish)
1-3 weeks post-infection
Swelling in face, legs, or around eyes
Fluid retention
Reduced urine output
Temporary decrease
High blood pressure
May be temporary
Fatigue
Lack of energy

Management

Treatment Options

1. Treat Underlying Infection
  • Antibiotics (if required)
2. Supportive Care
  • Blood pressure control
  • Fluid management
3. Monitoring
  • Regular kidney function tests
4. Dialysis (Rare, Severe Cases)
  • Required if kidney function declines significantly

When is Kidney Transplant Needed?

In most cases, transplant is not required.

Kidney damage becomes permanent

Patient progresses to chronic kidney disease

Dialysis becomes necessary

Most Patients Recover, But Monitoring is Important

Important: Usually Reversible

Many patients recover completely. Some may develop long-term kidney issues. Follow-up is essential to detect complications early.
