Glycosuria (glucose in urine) is most commonly associated with which condition?

Glycosuria happens when blood glucose levels are high enough to saturate the kidneys’ reabsorptive capacity, so glucose spills into the urine. The kidneys can reabsorb glucose up to a renal threshold of about 180 mg/dL; when hyperglycemia from diabetes mellitus exceeds this threshold, glucose appears in the urine. This is why diabetes mellitus is the condition most commonly associated with glycosuria. Dehydration concentrates urine but doesn’t cause glucose to appear unless glucose is already elevated; liver disease affects glucose production but glycosuria is not its typical feature; a urinary tract infection doesn’t directly cause glucose in urine.
