glomerulosclerose

**Glomerulosclerosis**

Glomerulosclerosis is a pathological condition characterized by the hardening and scarring of the glomeruli, the tiny blood vessel clusters in the kidneys responsible for filtering blood. This condition can lead to progressive kidney damage and chronic kidney disease (CKD). There are several types of glomerulosclerosis, including:

Primary glomerulosclerosis occurs independently of other kidney diseases and is often idiopathic, meaning its exact cause remains unknown. Secondary glomerulosclerosis, however, is associated with underlying conditions such as diabetes mellitus, hypertension, or systemic diseases like lupus or amyloidosis. In some cases, glomerulosclerosis may also result from prolonged exposure to certain toxins or medications.

The progression of glomerulosclerosis typically involves thickening of the glomerular basement membrane, accumulation of extracellular matrix proteins, and eventual fibrosis. Over time, this scarring reduces the kidney's ability to filter waste products and excess fluids, leading to symptoms such as fatigue, swelling in the legs or ankles, nausea, and changes in urine output. In advanced stages, severe glomerulosclerosis can result in end-stage renal disease (ESRD), requiring dialysis or kidney transplantation.

Diagnosis of glomerulosclerosis often involves a combination of clinical evaluation, laboratory tests (such as blood and urine tests), imaging studies, and a kidney biopsy. The biopsy allows pathologists to examine the glomerular structure under a microscope, confirming the diagnosis and identifying the specific type of glomerulosclerosis.

Management of glomerulosclerosis focuses on treating underlying causes, controlling blood pressure and blood sugar levels, and managing symptoms. Lifestyle modifications, such as a balanced diet, regular exercise, and avoiding tobacco, can also help slow disease progression. In advanced cases, renal replacement therapy is necessary to maintain fluid and electrolyte balance while the kidneys are unable to function adequately. Early detection and intervention are crucial for preserving kidney function and improving long-term outcomes.
