The presence of glucose in the urine, which is abnormal and usually a sign that blood sugar levels are too high, as in diabetes.
From Greek 'glukos' (sweet) + Latin 'urine' (urine). The term was coined in the 1800s by medical scientists observing sweet-smelling urine in diabetic patients, literally meaning 'sweet urine.'
Doctors in earlier centuries actually tasted patients' urine to diagnose diabetes because it literally tastes sweet when glucose spills into it—modern testing is definitely better!
