Nephrotic Syndrome

Disease Overview

Nephrotic Syndrome is a kidney disorder characterized by significant protein loss through urine due to damage in the kidney's glomerular filtration system. This condition disrupts the kidney's ability to filter waste and maintain proper fluid and electrolyte balance, leading to multiple systemic complications.

Disease Category

Renal Disorder; Glomerular Disease

Synonyms

• Nephrosis
• Protein-losing Nephropathy
• Lipoid Nephrosis (in children)

Signs & Symptoms

• Severe generalized edema (swelling)
• Foamy or frothy urine
• Significant protein loss in urine (proteinuria)
• Hypoalbuminemia
• Weight gain from fluid retention
• Increased susceptibility to infections
• Elevated blood cholesterol levels
• Fatigue and weakness
• Decreased appetite
• Potential blood clotting complications

Causes

• Primary Kidney Diseases
