Renal glycosuria is defined as the excretion of excessive amounts of glucose in the urine in the presence of normal filtered loads of glucose. Implicit in the definition is the concept of an abnormality in tubular glucose transport. Such an abnormality may occur in association with generalized proximal tubular dysfunction such as in the Fanconi's syndrome. FamiliaI renal glycosuria is an isolated defect in renal glucose transport in which intestinal glucose transport is normal. Glycosuria without hyperglycemia also may be observed in either pregnant women or patients with renal disease and glomerular filtration rates less than 15 ml per minute.
Familial glycosuria is a benign disease that has an excellent prognosis and requires no treatment.
Prolonged starvation must be avoided as it can lead to hypoglycemic episodes especially in Type A cases. Comments and Feedback . Privacy statement .
