Glomerulonephritis, often referred to as Glomerulus Nephropathy, is a type of kidney disease that affects the glomeruli—the tiny filtering units within your kidneys. This guide provides a detailed yet straightforward overview of glomerulonephritis, covering its definition, causes, symptoms, diagnosis, treatments, prevention, and frequently asked questions.
Glomerulonephritis is a condition where the glomeruli, small units within the kidneys that filter blood, become inflamed and damaged. This inflammation can impair the kidneys’ ability to remove waste and excess fluids from the body, leading to various health issues.
Key Points:
- Glomeruli: Tiny filters in the kidneys.
- Inflammation: Causes damage to these filters.
- Function Impact: Reduces the kidneys’ ability to filter blood effectively.
Pathophysiology
Understanding how glomerulonephritis affects the body involves looking at the structure of the glomerulus, its blood and nerve supply, and how inflammation disrupts its function.
Structure of the Glomerulus
- Glomerulus: A network of tiny blood vessels (capillaries) located at the beginning of each kidney podocyte.
- Function: Filters blood to remove waste products and excess substances while retaining necessary components like proteins and blood cells.
Blood Supply
- Renal Artery: Supplies oxygen-rich blood to the kidneys.
- Glomerular Capillaries: Receive blood from the renal artery, where filtration begins.
Nerve Supply
- Autonomic Nervous System: Regulates blood flow to the kidneys.
- Sensory Nerves: Help in detecting changes in blood pressure and composition.
How Inflammation Affects the Glomerulus
- Immune Response: The body’s immune system mistakenly attacks the glomeruli.
- Damage: Leads to scarring and thickening of the glomerular walls.
- Filtration Issues: Impaired ability to filter blood, leading to leakage of proteins and blood cells into urine.
Types of Glomerulonephritis
Glomerulonephritis can be classified based on its cause, duration, and severity. Here are the main types:
- Acute Glomerulonephritis: Sudden onset, often following an infection.
- Chronic Glomerulonephritis: Develops over time, leading to long-term kidney damage.
- Post-Infectious Glomerulonephritis: Occurs after infections like streptococcal throat infection.
- IgA Nephropathy (Berger’s Disease): Deposits of IgA antibodies in the glomeruli.
- Membranous Nephropathy: Thickening of the glomerular basement membrane.
- Focal Segmental Glomerulosclerosis (FSGS): Scarring in some parts of some glomeruli.
- Rapidly Progressive Glomerulonephritis (RPGN): Quick loss of kidney function.
- Lupus Nephritis: Caused by systemic lupus erythematosus.
- Goodpasture Syndrome: Autoimmune disorder affecting kidneys and lungs.
