Glomerulonephritis is a kidney condition that affects the tiny filtering units called glomeruli. This guide provides detailed yet simple explanations about glomerulonephritis, covering its anatomy, types, causes, symptoms, diagnostics, treatments, and more to help you understand and manage the condition effectively.
Glomerulonephritis is inflammation of the glomeruli, the small filters in your kidneys that remove waste and excess fluids from your blood. When these filters are damaged, your kidneys can’t effectively clean your blood, leading to waste buildup and other health issues.
Anatomy of the Kidneys
Structure
- Kidneys: Two bean-shaped organs located on either side of your spine, just below the rib cage.
- Glomeruli: Tiny blood vessel clusters within the kidneys that filter blood.
- Nephrons: Functional units of the kidney, each containing a glomerulus and tubules that process the filtered fluid.
Blood Supply
- Renal Arteries: Supply oxygen-rich blood to the kidneys.
- Afferent Arterioles: Carry blood into the glomeruli.
- Efferent Arterioles: Carry filtered blood away from the glomeruli.
Nerve Supply
- Renal Nerves: Control blood flow and kidney function through the autonomic nervous system.
Types of Glomerulonephritis
- Acute Glomerulonephritis: Sudden onset, often following infections.
- Chronic Glomerulonephritis: Gradual loss of kidney function over time.
- IgA Nephropathy: IgA antibodies build up in the kidneys.
- Post-Infectious Glomerulonephritis: Occurs after infections like strep throat.
- Rapidly Progressive Glomerulonephritis: Rapid loss of kidney function.
- Membranous Nephropathy: Thickening of the glomerular basement membrane.
- Focal Segmental Glomerulosclerosis (FSGS): Scarring in parts of the glomeruli.
- Goodpasture Syndrome: Affects kidneys and lungs.
