Etymology

Origin of diabetes

First recorded in 1555–65; from New Latin, Latin, from Greek, equivalent to diabē- (variant stem of diabaínein “to go through, pass over,” equivalent to dia- “through” + baínein “to pass”) + -tēs agent suffix; see dia-

Explanation

When a person has the medical condition called diabetes, the body can’t produce enough insulin to process the glucose in the blood. Diabetes has been known since the first century B.C.E., when a Greek physician, Aretus the Cappadocian, named it diabainein, meaning "a siphon," referring to the excessive urination associated with the disease. The word diabetes was first recorded in 1425, and in 1675, the Greek mellitus, “like honey,” was added, to reflect the sweet smell and taste of the patient’s urine. An unrelated and rare disorder, diabetes insipidus, is usually caused by a hormone deficiency.
