This can lead to proteinuria and eventually, chronic kidney disease. Heart failure: People with heart failure may experience reduced blood flow to the kidneys.Kidney diseases: Various diseases such as glomerular disease, nephritis, and kidney infections can damage the kidneys, leading to proteinuria.Chronic high blood pressure can put a strain on the kidneys and lead to kidney damage. Hypertension: High blood pressure is also another leading cause of proteinuria.Diabetes: High blood sugar levels in diabetes can damage the kidneys over time, leading to albuminuria, a form of proteinuria.

Proteinuria may be a sign of underlying health conditions or diseases like. Proteinuria can occur due to various reasons, but it typically results from damage to the glomeruli, tiny blood vessels in the kidneys responsible for filtering the blood. However, in proteinuria, the kidneys become damaged, and they start to leak out albumin and other proteins into the urine, and eventually, a significant amount of protein begins to be excreted out through urine. Generally, the kidneys filter waste products and excess fluids from the blood and excrete them in the form of urine.Īt the same time, the kidneys retain necessary and valuable proteins, such as albumin, and keep them in circulation in the bloodstream. Proteinuria is a condition characterised by the presence of excess protein, mainly albumin, in the urine.
