(from ''protein'' and ''urine'') means the presence of an
excess of serum
Protein s in the
Urine .
Proteinuria may be a sign of renal (
Kidney ) damage. Since serum proteins are readily reabsorbed from urine, the presence of excess protein indicates either an insufficiency of absorption or impaired filtration. Diabetics usually suffer from damaged
Nephrons and develop proteinuria.
With severe proteinuria, general
Hypoproteinemia can develop which results in
diminished
Oncotic Pressure . Symptoms of diminished oncotic pressure may include
Ascites ,
Edema , and hydrothorax.
