Bedwetting in children is often considered normal by many parents, as children's nervous systems are still developing. Limited response to and control over the urge to urinate can easily lead to bedwetting. However, as organs mature, this issue typically resolves gradually. Therefore, if a child over 5 years old continues to experience frequent bedwetting, parents should be vigilant, as it may signal an underlying condition.
Conditions such as urinary tract infections, hematuria, proteinuria, kidney stones, hydronephrosis, sleep disorders, phimosis, spina bifida occulta, anemia, or obesity can also cause bedwetting. If a child over 5 continues to wet the bed, prompt medical consultation is recommended. Currently, the most common diagnosis for frequent bedwetting in children over 5 is enuresis, which accounts for the majority of cases.
What is Enuresis?
Professor Yu Li, Chief Physician of Pediatrics at Guangzhou First People's Hospital (Expert Appointment), stated in a previous interview with Family Doctor Online that if a child over 5 years old wets the bed at night 2 or more times per week for 6 months or longer, it is highly likely they have enuresis. Enuresis can be classified as secondary or primary.
Causes of Enuresis
Common causes of secondary enuresis include urinary tract obstruction (e.g., urethral valves), cystitis, and neurogenic bladder (urinary dysfunction caused by neurological disorders).Primary enuresis primarily stems from the following causes:
1. Delayed development of the cerebral cortex, failing to inhibit the spinal urinary center. During sleep, the detrusor muscle undergoes uninhibited contractions, expelling urine.
2. Deep sleep preventing immediate awakening when the bladder expands after falling asleep.
3. Psychological factors, such as the child feeling unloved or neglected by parents.
4. Genetic predisposition, with a higher incidence of enuresis among the child's parents or siblings.Treatment for Enuresis For children over 5 years old who frequently wet the bed, parents should promptly seek medical evaluation. Once diagnosed, early intervention at a specialized nocturnal enuresis clinic is recommended, ideally beginning before school age. A comprehensive assessment identifies the cause and determines the most appropriate treatment strategy.For enuresis, common medications include imipramine, oxibunin, ephedrine, and desmopressin. The combination of amitriptyline, desmopressin, and oxibunin is currently considered an effective triple-drug regimen for treating refractory mixed enuresis. Professor Yu Li emphasizes that beyond medical interventions, parental cooperation is crucial in treating childhood enuresis.
First, parents should help children establish good sleep schedules and hygiene habits while avoiding overexertion. During treatment, track the child's bedwetting patterns and wake them 1–2 times at night using an alarm clock to urinate. Additionally, limit fluid intake after dinner and ensure the bladder is emptied before bedtime to reduce bedwetting episodes.
Most importantly, parents must provide psychological support during treatment. Chronic bedwetting can severely impact a child's mental health. Avoid mocking, scolding, or punishing the child, as this only increases their emotional burden. Show empathy and care to alleviate feelings of inferiority caused by bedwetting.Build your child's confidence in overcoming the condition through patient encouragement. Reward them when bedwetting episodes decrease, as this approach is key to achieving complete resolution of enuresis.
