Etymed
glycosuria
Definition
the presence of glucose in the urine, typically indicating impaired glucose metabolism or kidney dysfunction
Clinical context
A 45-year-old man presents with polyuria and polydipsia. His random blood glucose is 280 mg/dL and urinalysis shows significant glucose positivity. Further evaluation reveals impaired glucose tolerance. This patient's glycosuria is due to hyperglycemia exceeding the renal threshold for glucose reabsorption.
Mnemonic
Glycosuria = Glucose in urine = Glucose overload beyond kidney's capacity
