Definition
Nephrotic syndrome occurs when the kidneys let protein leak into the urine. When this happens, there is too little protein in the blood. Low protein in the blood allows fluid to leak out of the blood stream and into body tissues.
Nephrotic syndrome is a collection of the following signs and symptoms:
- High protein in the urine
- Low protein in the blood
- Swelling of body tissues
- High cholesterol in the blood
Nephrotic syndrome is not a disease itself. It is a set of signs and symptoms that indicate another disease has damaged the kidneys, and they are no longer working properly.
This is a serious condition that requires care from your doctor. Contact your doctor if you think you may have nephrotic syndrome.
