Glomerular diseases
Glomerular diseases affect the glomeruli, tiny blood-filtering units in the kidneys. These structures remove waste and excess fluids from the blood. When damaged, they can’t filter properly, leading to blood or protein leakage in urine.
Common Types of Glomerular Diseases
Several conditions fall under glomerular diseases. Each affects the glomeruli in different ways:
- Glomerulonephritis: Inflammation of the glomeruli.
- Focal Segmental Glomerulosclerosis (FSGS): Scarring in parts of the glomeruli.
- Minimal Change Disease: Common in children, often causes nephrotic syndrome.
- IgA Nephropathy: Immune deposits in the glomeruli.
- Membranous Nephropathy: Thickening of the glomerular walls.
These diseases can be primary (kidney-based) or secondary (from other conditions like lupus or diabetes).
Symptoms of Glomerular Diseases
- Foamy or dark-colored urine
- Swelling in legs, face, or abdomen
- High blood pressure
- Fatigue and weakness
- Decreased urine output
- Blood in the urine (hematuria)
Early stages may be silent, so regular screenings help.
Causes and Risk Factors
- Autoimmune diseases (like lupus)
- Infections (hepatitis B, C, strep)
- Genetic mutations
- Diabetes or high blood pressure
- Certain medications or toxins
Family history and ethnicity may also influence risk.
How Are Glomerular Diseases Diagnosed?
- Urine tests: Check for protein and blood.
- Blood tests: Measure creatinine and urea levels.
- Kidney biopsy: A sample examined under a microscope.
- Imaging tests: Ultrasound shows kidney size and shape.
Diagnosis helps decide the best treatment approach.
Treatment of Glomerular Diseases
- Medications: Immunosuppressants, corticosteroids, ACE inhibitors, or ARBs.
- Dietary changes: Reduce salt, protein, and fat intake.
- Blood pressure control: Essential to protect kidney function.
- Dialysis or transplant: For advanced cases or kidney failure.
Early treatment prevents long-term damage.
Managing Daily Life with Glomerular Disease
- Stick to a kidney-friendly diet.
- Monitor blood pressure and sugar levels.
- Avoid smoking and alcohol.
- Take medicines as prescribed.
- Stay active but avoid strenuous activities if swelling or fatigue occurs.
Children and Glomerular Disease
In children, minimal change disease and IgA nephropathy are more common. Kids may present with swelling, fatigue, or frequent urination. Pediatric nephrologists manage diagnosis and treatment carefully to support growth and development.
Possible Complications
- Chronic kidney disease (CKD)
- End-stage renal disease (ESRD)
- Anemia or bone disorders
- Heart disease
- Fluid overload and severe hypertension
Managing symptoms early can delay or prevent complications.
When to Seek Medical Help
- Blood in urine
- Persistent swelling
- Sudden weight gain
- High blood pressure
- Decreased urine output
Prompt evaluation ensures timely care and better outcomes.
