Proteinuric kidney disease means your kidneys are leaking protein into the urine—something they should not normally do. This often happens silently and may only be picked up through routine urine tests. Despite its quiet onset, proteinuria is a serious sign of kidney damage and should never be ignored. If left untreated, it can lead to progressive kidney failure and is strongly linked to an increased risk of heart disease and stroke. At very high levels, protein loss can also increase the risk of infections and blood clots. There are many possible causes, and identifying the underlying driver is key to guiding treatment and assessing long-term risk.
Management focuses on reducing protein leakage and protecting kidney function through blood pressure control, dietary changes, and medications that support the kidney’s filtering system. Ongoing monitoring is essential to track progress, adjust treatment, and reduce the risk of complications. With early detection and the right care, long-term kidney and heart health can be preserved.
