The kidneys are responsible for filtering waste products, salts and other chemicals and excreting then from the body as part of urine. Normally, only small amounts of protein are found in the urine because the kidneys are able to keep proteins from getting out of the blood. The presence of significant amounts of protein in the urine, also known as proteinuria, is a sign that your kidneys have become damaged, which means you will need to take steps to help prevent more protein from entering into your urine.
Determine the cause of your proteinuria. The leading cause of proteinuria in the United States is diabetes, according to the National Institute of Diabetes and Digestive and Kidney Disorders. Another common cause of protein appearing in the urine is high blood pressure. Both conditions can impair the ability of the kidneys to filter protein out of the urine. In some rare instances, protein in the urine can be caused by other conditions, such as cancer, which can be diagnosed by looking at which proteins are appearing in your urine.
Lower your blood pressure and blood glucose levels. This is particularly important if your doctor believes that hypertension or diabetes are responsible for the protein in your urine. The National Institute of Diabetes and Digestive and Kidney Disorders says that many people with proteinuria and high blood pressure benefit from taking medications known as angiotensin-converting enzyme inhibitors, or ACE inhibitors, because they lower blood pressure and protect the kidneys.
Reduce the salt and protein in your diet. Salt and protein in your diet can put extra strain on your kidneys, resulting in them having trouble working properly. As a result, you may benefit from reducing the amount of salt and protein in your diet. Your doctor may recommend that you meet with a nutritionist to determine how much salt and protein you consume and how you can cut back on these substances.
