What Causes Nephrotic Syndrome?
Nephrotic Syndrome can be “primary” or “secondary” in nature.
Primary Nephrotic Syndrome

- Minimal Change Disease (MCD) – most common in children
- Focal Segmental Glomerulosclerosis (FSGS)
- Membranous Nephropathy (MN) – most common in adults

- Vasculitis: Lupus
- Infection: Hepatitis, HIV, CMV, others
- Metabolic disorder: Diabetes
- Cancer: Lymphoma
- Renal Vein Thrombosis
