Enuresis refers to the recurrent involuntary urination of children over 5 years of age during sleep at night due to lack of control, also known as nocturnal incontinence or bedwetting. Sudden enuresis in children can be divided into primary enuresis and secondary enuresis, which can be caused by genetic factors, sleep-wake disorders, developmental delays and organic diseases. You should seek medical attention for relevant examinations to clarify the cause and then treat the symptoms. Common causes 1. Genetic factors: Urine loss has a genetic tendency, so it can lead to urine loss due to genetics; 2. Sleep-wake disorder: When children sleep at night, it may be difficult to be awakened due to deeper sleep. So when the bladder fills up leading to urination, it is not yet awake itself; 3. Developmental delay: Usually during sleep, the brain’s control ability decreases, and if the child’s brain center is not well developed, it may also cause enuresis; 4. Organic diseases: Some organic lesions can also cause enuresis, such as urinary tract infections, lower urinary tract malformations and other urinary system diseases, mental retardation, tics and other mental diseases. In girls, urinary tract infections can lead to enuresis because of the shorter urethra. Boys may suffer from enuresis due to prepuce and phimosis. Treatment measures 1. Daily care: Children under 6 years old can be treated for enuresis mainly through education and life guidance, and generally do not need medication. Children should develop the habit of regular daytime urination and bedtime urination, and avoid excessive excitement before bedtime. 2. Medication: Usually, drugs such as desmopressin, promethazine, and tolterodine need to be used under the guidance of a professional doctor to relieve the symptoms of enuresis. If it is caused by disease, symptomatic treatment is also needed for the primary disease; 3. Surgery: If the boy has the problem of overcircumcision, circumcision can be performed. Some children’s enuresis can gradually disappear with age, and most of them can be cured after medication and improvement of living habits. Therefore, parents need to face the problem together with their children, pay attention to their psychological changes, and cultivate a confident and optimistic attitude to relieve the symptoms of enuresis.
