=== Polydipsia and polyuria ===
* Frequency that is the result of polydipsia and resulting polyuria may mimic OAB
*'''Diagnosis and Evaluation'''
**'''Can only be distinguished from OAB with the use of frequency-volume charts.'''
***'''In OAB, urinary frequency is associated with many small volume voids.'''
***'''In polydipsia, urinary frequency is associated with normal or large volume voids and the intake is volume matched.''' In this case, the frequency is appropriate because of the intake volume and the patient does not have OAB
***'''Diabetes insipidus''' also is associated with frequent, large volume voids and should be distinguished from OAB.
*Management
**If polydipsia-related frequency is physiologically self-induced: education and consideration of fluid management
**If diabetes insipidus: desmopressin
