Proteinuria means there’s too much protein in your urine. Normally, proteins should stay in your blood to help your body grow, repair tissues, and stay healthy. Healthy kidneys act like filters, keeping proteins in and removing waste. If your kidneys are damaged or not working properly, some of these proteins can “leak” into your urine and leave your body. Over time, losing too much protein this way can harm your overall health. Proteinuria is usually detected through simple urine and blood tests. If you notice foamy urine or have risk factors like diabetes, high blood pressure, or a family history of kidney problems, consult a doctor for proper evaluation and treatment. Early detection can protect your kidneys and your health.
