The patient must either experience a frequency of inappropriate voiding at least twice a week for a period of at least 3 consecutive months OR experience clinically significant distress or impairment in social, occupational or other important areas of functioning, in order to be diagnosed with enuresis. These symptoms must not be due to any underlying medical condition (e.g. a child who wets the bed because their kidneys produce too much urine, is not suffering from enuresis, they're suffering from kidney disease which is causing the inappropriate urination). Also, these symptoms must not be due exclusively to the direct physiological effect of a substance (such as a diuretic or antipsychotic).
