Frequent urination, or urinary frequency, can be defined as the need to urinate more often than usual. It is often, though not necessarily, associated with urinary incontinence and large total volumes of urine. However, in other cases, urinary frequency involves only normal volumes of urine overall. Frequent urination is often accompanied by other coinciding effects such as dehydration and dry mouth in a manner which further amplifies the needs to urinate through excessive consumption of water. It is most commonly induced under the influence of moderate dosages of a wide variety of compounds, such as stimulants, psychedelics, dissociatives, and deliriants.
