How to Reduce Protein in Urine

Protein in the urine, also known as proteinuria or albuminuria, means that your kidneys are leaking protein. While small amounts of protein in the urine may be normal, large or persistent amounts may indicate kidney stress or damage. Therefore, reducing protein in the urine lowers the risk of kidney decline and heart problems. For this reason, clinicians actively treat proteinuria.

What Causes Protein in Your Urine?

When your kidneys are healthy, they remove waste and extra fluid from your blood and turn it into urine. Healthy kidneys don’t remove proteins or other key nutrients. However, when your kidneys are failing or damaged, they may allow protein to leak into the urine, increasing the level of protein content.

Common health problems that cause persistent levels of protein in the urine include:

Nephrotic syndrome
Pregnancy and preeclampsia
Kidney disease

There are also risk factors that could increase your risk of developing kidney disease, such as:

High blood pressure
Family history of kidney conditions
Diabetes

Tips to Reduce Protein in Urine

Reducing protein in the urine requires treating the underlying condition. Here are ways to reduce protein in urine:

Control Blood Pressure

High blood pressure increases pressure inside the kidney filters. Lowering blood pressure reduces this pressure and the amount of protein leaking into your urine. Your doctor may prescribe medications that block the renin–angiotensin system (ACE inhibitors or ARBs) to lower blood pressure and directly reduce proteinuria.

These drugs are often the first-line treatment for patients with significant proteinuria. Be sure to follow your clinician’s instructions for a safe blood pressure target.

Use SGLT2 Inhibitors when Prescribed

SGLT2 inhibitors, such as dapagliflozin or canagliflozin, have been tested in large kidney trials. These drugs reduce albuminuria and slow kidney disease progression. They have been effective for people with and without diabetes in many studies. If you qualify, your nephrologist or primary doctor may prescribe an SGLT2 inhibitor to help lower protein in urine.

Control Diabetes (if you have it)

High blood sugar can damage the kidney’s filtering units. Tight but safe glycemic control can lower microvascular harm and reduce albuminuria in many patients. Therefore, it’s important to use approved diabetes treatments and follow the target glucose ranges set by your healthcare team. Newer diabetes drugs can also benefit the kidneys beyond lowering glucose.

Manage Your Sodium Intake

High sodium intake increases blood pressure and may reduce the effectiveness of protein-lowering drugs. Reducing sodium intake helps medications work better and lowers urine protein. Very low-protein diets have shown mixed results. For some people with advanced kidney disease, modest protein reduction may slow progression.

Diet changes should be individualized and supervised by a dietitian or nephrologist to avoid malnutrition.

Lifestyle Changes May Help

Smoking increases kidney damage and the risk of proteinuria. If you smoke, consider quitting the habit. Maintaining a healthy weight and engaging in moderate physical activity can support healthy blood pressure and metabolic processes. These steps support kidney protection alongside medical therapy.
