insipidus: from Late Latin: insipidus "tasteless," from Latin in- "not" + sapidus "tasty", from sapere "to taste".This is because patients experience polyuria (an excretion of over 2.5 liters of urine per day), and the urine does not have an elevated glucose concentration, as opposed to diabetes mellitus. The two diseases were named (in ancient times) for the fact that one features polyuria in which the urine tastes sweet, whereas the other features polyuria in which the urine tastes unremarkable.Although they share part of their names, diabetes mellitus and diabetes insipidus are two separate conditions. Both cause excessive urination (hence the similarity in name), but whereas diabetes insipidus is a problem with the production of antidiuretic hormone (neurogenic diabetes insipidus) or the kidneys response to antidiuretic hormone (nephrogenic diabetes insipidus), diabetes mellitus causes polyuria via osmotic diuresis, due to the high blood sugar leaking into the urine, taking excess water along with it.
