The most common symptoms are a result of abnormal loss of protein from the glomerulus of the kidney, and include: * Frothy urine (due to excess protein) * Excess water retention (pitting edema, due to loss of serum albumin) * Susceptibility to infection (due to loss of serum antibodies) Common signs are also due to loss of blood proteins by the glomerulus of the kidney, including: * Protein in the urine (Proteinuria , often in the nephrotic range of >3.5 g/day) * Low serum albumin (<3.5 g/dl) * Low serum antibodies * High cholesterol (compensatory by the liver to compensate for low serum oncotic pressure) * Fatty casts in the urine (secondary to hypercholesterolemia)
