Healthy kidneys remove excess fluid and various waste from your body, while also preventing proteins and other nutrients from leaving your body. In the case of the kidneys functioning incorrectly, they allow albumin to get through the filters into the urine.
Increased level of protein in the urine is called proteinuria (or albuminuria) and can be an early symptom of kidney disease. Most often, this state is diagnosed when running common tests.
Who belongs to the risk group?
The most common factors that increase the risk of developing proteinuria include:
- high blood pressure (hypertension).
Both these conditions may cause damage to the kidneys, which can then lead to proteinuria.
Other factors that contribute to the increased level of protein in urine include:
- certain medications;
- immune perturbation.
The causes of proteinuria
As it has been mentioned earlier, some diseases and conditions allow the protein to be supplied directly to urine through the filters. Along with this, its presence in the urine doesn't always indicate the damage of kidneys. The following points can be other causes of proteinuria:
- physical load.
How to diagnose proteinuria?
The cunningness of this condition lies in the fact that it may be inevident for a long time. The only way to ascertain whether you have it is to run a urine test. It involves determining the albumin-creatinine ratio (ACR). If the protein content in the urine exceeds 30 mg/g, it may evidentiate kidney disease.
The increased level of protein and damaged kidneys may be followed by the next symptoms:
- foamy or bubbly urine;
- arm, leg, stomach, or facial swelling.
The occurrence of these symptoms may indicate serious kidney disease. Upon discovering them, we recommend you to visit a doctor as soon as possible. A medical professional will help you to get diagnosed and will prescribe proper treatment.
