Abnormally high amounts of sugar in the urine, known as glycosuria, are usually the result of high blood sugar levels. Since your blood sugar levels are normal, this could be due to renal glycosuria. In general, renal glucosuria is a benign condition and does not require any specific therapy. Glucosuria may be associated with tubular disorders such as Fanconi-de Toni-Debre syndrome, cystinosis, Wilson disease, hereditary tyrosinemia, or oculocerebrorenal osteodystrophy (Lowe syndrome). Renal glucosuria has also been reported in patients with acutepyelonephritis in the presence of a normal blood glucose level.
I would advise that you get a urinalysis, fasting blood glucose concentration, glycosylated hemoglobin levels, serum electrolytes, bicarbonate, phosphorus, and uric acid levels and a 24-hour urine collection for amino acids. Benign renal glucosuria is a self-limiting process and requires no special medical care. If other associated findings suggest tubular disorders, then other interventions are required.
