Nephrotic Syndrome

Nephrotic Syndrome is a kidney disorder that affects millions of people worldwide. Whether you or a loved one has been diagnosed with this condition or you’re simply curious to learn more, this guide provides a clear and comprehensive overview. We’ll cover everything from basic definitions and anatomy to causes, symptoms, treatments, and frequently asked questions—all explained in simple language to ensure easy understanding.

Nephrotic Syndrome is a kidney disorder that causes your body to excrete too much protein in your urine. Normally, your kidneys filter waste and extra water from your blood, keeping proteins in your body. When you have Nephrotic Syndrome, this filtering process is disrupted, leading to a significant loss of protein. This can result in various health issues, including swelling, especially around the eyes, ankles, and feet.

Key Points:

• Protein Loss: Excessive protein loss in urine.
• Swelling: Commonly in the face, ankles, and feet.
• Kidney Function: Impaired ability to filter blood properly.

Anatomy Related to Nephrotic Syndrome

Understanding the parts of the kidney involved in Nephrotic Syndrome can help you grasp how the condition affects your body.

Structure

The kidneys are two bean-shaped organs located on either side of your spine, just below your ribcage. Each kidney contains around a million tiny filtering units called nephrons. Nephrons consist of:

• Glomerulus: A tiny blood vessel (capillary) where blood is filtered.
• Tubules: Structures that process the filtered fluid, reabsorbing essential substances and excreting waste.

Blood Supply

The kidneys receive a rich blood supply to perform their filtering functions. Blood enters the kidneys through the renal artery, which branches into smaller arterioles and reaches the glomerulus in each nephron. After filtering, the blood exits through the renal vein.

Nerve Supply

The kidneys are innervated by the autonomic nervous system, which regulates blood flow and filtration rates. This nerve supply helps maintain the kidneys’ ability to respond to changes in the body’s needs.

Types of Nephrotic Syndrome

Nephrotic Syndrome can be classified based on its underlying cause:

1. Primary Nephrotic Syndrome: Occurs due to diseases directly affecting the kidneys.
   • Minimal Change Disease: Most common in children; causes damage to the kidney’s filtering units.
   • Focal Segmental Glomerulosclerosis (FSGS): Scarring in parts of some glomeruli.
   • Membranous Nephropathy: Thickening of the glomerular basement membrane.
2. Secondary Nephrotic Syndrome: Results from systemic diseases affecting the kidneys.
   • Diabetes Mellitus: High blood sugar can damage kidney filters.
   • Lupus (Systemic Lupus Erythematosus): An autoimmune disease that can target the kidneys.
   • Infections: Such as HIV or hepatitis.
