Glomerular disease refers to a group of conditions that damage the glomeruli, the tiny filtering units within your kidneys. These diseases can impair the kidneys’ ability to filter blood effectively, leading to various health complications. This guide provides an in-depth look at glomerular disease, including its structure, causes, symptoms, diagnostic tests, treatments, and preventive measures,
Glomerular disease involves damage to the glomeruli, which are tiny structures within your kidneys responsible for filtering waste and excess fluids from your blood. When these filters are damaged, waste products and fluids can build up in your body, leading to serious health issues.
Pathophysiology of Glomerular Disease
Understanding how glomerular disease affects your body requires a basic knowledge of kidney structure and function.
Structure
Each kidney contains about a million glomeruli. These are tiny ball-like structures made up of blood vessels and specialized cells. They act as filters, removing waste products and excess substances from the blood to form urine.
Blood Supply
Blood flows into the kidneys through the renal arteries, branching into smaller arterioles that supply each glomerulus. The glomerulus filters the blood, allowing waste and excess fluids to pass into the Bowman’s capsule, while retaining essential components like proteins and blood cells.
Nerve Supply
The kidneys receive nerve signals that help regulate blood flow, filtration rate, and other functions. The autonomic nervous system controls these nerves, ensuring that the kidneys respond appropriately to the body’s needs.
Types of Glomerular Disease
There are several types of glomerular diseases, each affecting the glomeruli in different ways:
- IgA Nephropathy (Berger’s Disease): Caused by deposits of the protein IgA in the glomeruli.
- Membranous Nephropathy: Characterized by thickening of the glomerular basement membrane.
- Focal Segmental Glomerulosclerosis (FSGS): Involves scarring in parts of some glomeruli.
- Minimal Change Disease: Causes significant protein loss without visible changes under a regular microscope.
- Post-Infectious Glomerulonephritis: Develops after infections like strep throat.
- Rapidly Progressive Glomerulonephritis: Leads to rapid loss of kidney function.
- Goodpasture’s Syndrome: An autoimmune disease affecting the kidneys and lungs.
- Alport Syndrome: A genetic condition affecting the glomeruli and hearing.
- Diabetic Nephropathy: Caused by diabetes damaging the glomeruli.
- Lupus Nephritis: A complication of lupus affecting the kidneys.
Causes of Glomerular Disease
Glomerular disease can result from various factors, including:
- Autoimmune Diseases: Conditions like lupus can attack the glomeruli.
