The term nocturia denotes an abnormally strong need to urinate at night. It can be due to mundane causes, such as the consumption of too much liquid before going to bed. Some adults can also present with liver problems leading to liver impairment, with some men affected by benign
prostate hyperplasia. If the patient has to get up an abnormally high number of times during the night, it is called urinary frequency
. Nocturia is also possible in children who are not yet potty trained or in the process of learning, this is called primitive enuresis. When an already potty-trained child continues to urinate abnormally, it is called secondary enuresis. Enuresis most frequently occurs at night.
