Nephrotic syndrome occurs when the kidneys leak large amounts of protein (mostly albumin) into the urine. Protein lost in the urine results in a lower level of proteins in the blood. It is these proteins in the blood which help to hold water within the blood vessels. Therefore, when the protein level is very low, water passes into the tissues and this is recognised as swelling (oedema).
