Nephrotic Syndrome is a kidney disorder that affects both children and adults. It causes the body to excrete too much protein in the urine, leading to various health issues. This guide breaks down everything you need to know about Nephrotic Syndrome in simple terms,
Nephrotic Syndrome is a condition where the kidneys leak an excessive amount of protein into the urine. This happens because the tiny blood vessels in the kidneys, called glomeruli, become damaged. When glomeruli don’t work properly, protein that should stay in the blood leaks into the urine.
Key Points:
- Kidney Function: Filters waste and excess substances from the blood.
- Protein Leakage: Leads to low protein levels in the blood.
- Swelling: Caused by fluid retention due to low protein.
Pathophysiology
Kidney Structure
The kidneys are vital organs that filter blood, removing waste and excess substances to form urine. Each kidney contains about a million tiny filtering units called nephrons. Nephrons consist of:
- Glomerulus: A network of tiny blood vessels that filter blood.
- Tubules: Structures that process the filtered fluid to form urine.
Blood and Nephrotic Syndrome
In Nephrotic Syndrome:
- Increased Permeability: Glomeruli become more permeable, allowing proteins like albumin to leak into the urine.
- Low Blood Protein: Leads to decreased oncotic pressure, causing fluid to leak into tissues and causing swelling (edema).
Nerve Supply
The kidneys receive nerve signals from the autonomic nervous system, which helps regulate blood flow and kidney function. However, nerve supply is not a primary factor in Nephrotic Syndrome’s pathophysiology.
Types of Nephrotic Syndrome
Nephrotic Syndrome can be categorized based on its cause and age of onset:
- Primary (Idiopathic): Originates within the kidneys without a known external cause.
- Minimal Change Disease: Common in children; kidneys appear normal under a microscope.
- Focal Segmental Glomerulosclerosis (FSGS): Scarring in some parts of the kidneys.
- Membranous Nephropathy: Thickening of the glomerular basement membrane.
- Secondary: Caused by other diseases or conditions.
- Diabetes Mellitus: High blood sugar damages the kidneys.
- Lupus: An autoimmune disease attacking kidney tissues.
- Infections: Such as hepatitis or HIV.
- Medications: Certain drugs can harm the kidneys.
