10 Possible Causes of Proteinuria or Foamy Urine

10 Possible Causes of Proteinuria or Foamy Urine

Proteinuria is a common symptom of Chronic Kidney Disease (CKD). It means there is excess protein in urine.

Healthy kidneys do not allow large amounts of protein to pass through their filters. But with kidney disease, filters may allow proteins such as albumin to seep into urine from the blood.

The presence of protein in the urine may not cause any symptoms until it is detected on examination. However, in some cases, a person's urine may look frothy.

Causes of proteinuria

The two most common causes of urinary protein (risk factors) are:


-High blood pressure

Both diabetes and high blood pressure can damage the kidneys, leading to proteinuria.

Other kidney diseases unrelated to diabetes or high blood pressure can also cause proteins to leak into the urine. Other examples that cause proteinuria include:





-Immune system disorder

An increase in protein in the body can lead to albuminuria. For example, multiple myeloma and amyloidosis.

Other risk factors for kidney disease and proteinuria include:

-Age - over 65


-Family history of kidney disease

-Race and ethnicity: Asians are more likely to develop kidney disease and proteinuria.

Some people have more protein in their urine when they're standing than when they're lying down. This is called orthostatic proteinuria.

Proteinuria treatment

Urine protein is not a specific disease, but a symptom. So its treatment depends on identifying and managing its underlying causes. If it is kidney disease, proper medical management is crucial.

People with Nephrotic Syndrome and fluid overload should limit salt in their diets. Nephrologists may also recommend modest limits on protein intake.

Untreated chronic kidney disease can lead to Kidney Failure.

With mild or transient proteinuria, treatment is not required.

Sometimes drugs are prescribed, especially in people with Diabetes and/or hypertension, including two types of drugs:

-ACE inhibitors (ACEI)

-ARBs drugs (angiotensin receptor blockers)

Proper treatment, especially in patients with chronic diseases such as diabetes and hypertension, is essential to prevent progressive kidney damage that leads to urinary protein.

In Chinese Medicine Center, Chinese medicine is mainly used. It can help repair kidney damage and improve renal function so as to make proteinuria negative.
