There are some children who continue to experience nighttime bedwetting after the age of 5. When bedwetting occurs only during sleep, we call it nocturnal enuresis. It is usually a problem for about 1 in 4 children around the age of 5, and the incidence drops to 1 in 5 by the age of 7. The vast majority of children with enuresis are boys, and there is often a family history of bedwetting. There are many possible causes of enuresis. For example, the child’s neuromuscular and whether the feeling of a full bladder at night is subconsciously inhibited, so for most children, bedwetting is a functional problem, as long as the parents pay attention to care, wake up the child regularly at night to urinate, and remove the factors that may cause the child’s bedwetting in his life, the urine loss of a small child can be corrected. There are a number of diseases that can cause bedwetting, such as pinworms, urinary tract infections, spina bifida, sacral nerve dysfunction, epilepsy, and so on. There are also children who sleep too deeply, i.e., they sleep too much, and this results in enuresis. When the climate of the child’s environment changes and the child drinks more water before going to bed, this situation also tends to cause the child to wet the bed. There are also children who are not trained to urinate, long-term use of diapers, parents do not wake up at night, and some parents help their children to urinate while they are lying in bed, resulting in a habit of urination during sleep, which can easily lead to enuresis over time. Pediatric enuresis is still a relatively common symptom. Once appeared, parents should actively search for the cause, the vast majority of them are functional. At the same time, the child must develop good habits. Only particularly serious need oral medication.
