Excessive glomerular permeability due to primary glomerular disease

Q The most common cause of proteinuria is:

Fanconi's syndrome

Excessive glomerular permeability due to primary glomerular disease

failure of adequate tubular reabsorption

overflow proteinuria due to increased plasma concentration of immunoglobulins

diabetes

Glomerular proteinuria is the most common type of proteinuria and results from increased glomerular capillary permeability to protein, especially albumin. Glomerular proteinuria occurs in any of the primary glomerular diseases such as IgA nephropathy or in glomerulopathy associated with systemic illness such as diabetes mellitus.
