When you have proteinuria, does it mean you get kidney disease?

Does it all mean you have kidney disease when you have protein in urine? We know proteinuria is an important indicator of chronic kidney disease, so once people have protein in urine or bubbly urine, they suspect of having chronic kidney disease. Generally speaking, proteinuria is a significant sign of kidney damage, but other causes can also cause proteinuria in urine. We hope you can learn more about proteinuria from the following.

Usually, people with proteinuria have urine with an abnormal amount of protein. This condition is often a sign of kidney disease. This is because healthy kidneys do not allow a significant amount of protein to pass through their filters. However, when filters are damaged by kidney disease, it may let proteins such as albumin leak from the blood into the urine. Besides, diabetes and high blood pressure can cause damage to the kidneys, which are two risk factors for proteinuria.

What is more, other types of kidney disease that are unrelated to diabetes and high blood pressure can also lead to proteinuria. Other causes include: medications, trauma, toxins,infections and immune system disorders.

If you consume much protein in your diet, it can also lead to proteinuria. Examples include multiple myeloma and amyloidosis.

Other risk factors for proteinuria include:

Obesity

Age over 65

Family history of kidney disease

Race and ethnicity: African-Americans, Native Americans, Hispanics, and Pacific Islanders are more likely than whites to have high blood pressure and develop kidney disease and proteinuria.

If you stand for a long time, proteinuria is more likely to appear.

Proteinuria is not a specific disease, so once you have proteinuria, you should identify and manage its underlying cause. If it is caused by kidney disease, appropriate medical management is essential, because untreated chronic kidney disease can lead to kidney failure. Therefore, proteinuria does not all mean kidney disease and other causes can also induce proteinuria. And you should do tests to make sure its underlying cause and then take effective treatment to treat proteinuria.
