What syndrome is a condition characterized by high levels of protein in the urine and low levels of protein in the blood?

The condition characterized by high levels of protein in the urine and low levels of protein in the blood is known as nephrotic syndrome. This syndrome results from damage to the kidneys' filtering units, leading to excessive protein leakage into the urine. Common causes include minimal change disease, focal segmental glomerulosclerosis, and membranous nephropathy. Symptoms can include swelling, particularly in the legs and around the eyes, and increased risk of infections and blood clots.
