Proteinuria is a sign of chronic kidney disease. It is a condition in which abnormal amounts of protein are excreted in the urine. Normally, the body maintains the protein for later use depending on the cell. However, proteinuria in the kidneys prevents them from taking the protein from the blood. Consult your doctor for specific recommendations if you have proteinuria.
Risks and Symptoms of Proteunuria
People with certain conditions are more likely to develop proteinuria. In the United States, diabetes is the most frequent risk factor associated with the disease. People with hypertension or high blood pressure are also more likely to develop kidney disease. Often, during the early stages of proteinuria, there are no symptoms present. The urine in the toilet can be frothy because of an excess of proteins. Edema or swelling of the hands, face or abdomen may occur when the disease has progressed.
Diet can affect proteinuria. If you are diabetic, it is important that you maintain a healthy blood sugar level. MedlinePlus recommends that you consult a registered dietitian to determine what foods you can eat with proteinuria. Because proteinuria involves an excess of protein in the urine, a low-protein diet is often recommended. Research published in "Kidney International" in 1997 found that a low-protein diet reduces abnormalities in blood chemistry in patients with moderate chronic kidney disease.
The protein in the blood helps absorb excess fluid. Without the protein in the blood, fluid accumulates in the hands and feet, which leads to swelling. Excess sodium can also cause water retention and fluid buildup. To reduce edema, a low sodium diet is often recommended. If hypertension is the cause of proteinuria, a diet low in sodium is even more important to control your blood pressure. Consume products that contain low levels of sodium and do not add salt to any of your foods.
Other changes in your diet
Depending on the conditions of your proteinuria and the progress of your kidney disease, you may have to restrict other parts of your diet. If you have diabetes, limit your carbohydrates, as they become sugar. Limit the dairy foods you eat too. When it comes to kidney disease, your kidneys may not be able to process the dairy. Phosphorus, found in some fruits and vegetables, is another important mineral that you may need to reduce. Potassium can also accumulate if your kidneys are not functioning properly.Avoid foods rich in potassium.
