Glomerulus disorders are conditions that damage the glomeruli, which are tiny blood vessels in your kidneys responsible for filtering waste and excess fluids from your blood. When these filters are damaged, waste can build up in your body, leading to serious health issues.
Pathophysiology of Glomerulus Disorders
Understanding how glomerulus disorders develop involves looking at the structure of the glomerulus, its blood supply, and nerve connections.
Structure of the Glomerulus
The glomerulus is a network of tiny blood vessels called capillaries. These capillaries form a ball-like structure inside a capsule called Bowman’s capsule. Blood enters the glomerulus through an afferent arteriole and exits via an efferent arteriole. The walls of the capillaries allow certain substances like water, salts, and waste to pass through while keeping larger molecules like proteins and blood cells in the blood.
Blood Supply
Blood flows into the glomerulus through the afferent arteriole and exits through the efferent arteriole. This flow is crucial for filtering blood efficiently. Any disruption in blood flow can impair the kidney’s ability to filter waste.
Nerve Supply
The kidneys receive nerve signals from the autonomic nervous system, which helps regulate blood flow and filtration rates. These nerves play a role in maintaining kidney function and responding to changes in the body’s needs.
Types of Glomerulus Disorders
There are several types of glomerulus disorders, each with unique characteristics:
- Glomerulonephritis: Inflammation of the glomeruli.
- Nephrotic Syndrome: Causes excessive protein loss in urine.
- Minimal Change Disease: Mostly affects children, leading to nephrotic syndrome.
- Focal Segmental Glomerulosclerosis (FSGS): Scarring in parts of the glomeruli.
- Membranous Nephropathy: Thickening of the glomerular basement membrane.
- IgA Nephropathy: Deposits of the antibody IgA in the glomeruli.
- Rapidly Progressive Glomerulonephritis: Quick loss of kidney function.
- Post-Infectious Glomerulonephritis: Occurs after infections like strep throat.
- Alport Syndrome: Genetic disorder affecting the glomeruli.
- Goodpasture Syndrome: Autoimmune disease affecting kidneys and lungs.
