Nephrotic syndrome can cause severe swelling when the kidneys filter too much protein from the blood.
Nephrotic syndrome occurs when the blood-filtering function of the kidneys is impaired. Normally, clusters of tiny blood vessels (glomeruli) in the kidneys clean the blood by removing excess fluids and toxins, which are eliminated from the body in the form of urine. When functioning properly, the glomeruli do not remove blood proteins, which perform many vital functions, such as maintaining an optimal balance of fluids in circulation. When damaged, however, the glomeruli may allow a high volume of proteins to seep out of the blood and into the body’s soft tissues, resulting in nephrotic syndrome.
Causes of Nephrotic Syndrome
Nephrotic syndrome is not a type of kidney disease; instead, it is a symptom of glomeruli damage that allows proteins to leak from the blood. Some medical conditions that can cause the type of glomeruli damage that leads to nephrotic syndrome include:
- Reflux nephropathy
Signs of Nephrotic Syndrome
Nephrotic syndrome may cause:
- Severe swelling (edema) in the ankles or feet, particularly after extended standing
- Swelling around the eyes, especially in the morning
- Weight gain due to fluid retention
- Foamy or bubbly urine
- Loss of appetite
- Unexplained fatigue
Diagnosis of Nephrotic Syndrome
If nephrotic syndrome is suspected, a physician will typically order one or more diagnostic tests, such as:
- A urinalysis to check for proteins in the urine
- Bloodwork to assess kidney function
- A kidney biopsy
Treatments for Nephrotic Syndrome
The goals of nephrotic syndrome treatment are to resolve or control the underlying medical condition that is causing it, slow the progression of kidney damage and prevent end-stage renal failure.
