What causes bedwetting in 6-year-old children?

Children aged 6 are considered to be relatively sensible, but some of them wet the bed. There are many reasons why babies of this age wet the bed, such as genetic factors, delayed bladder maturation, and too deep sleep. Many parents find that their 6-year-old children wet the bed and don’t know what caused it. What is bedwetting? Let’s take a look at it next.

1. Genetic factors

30% of the fathers of children with enuresis and 20% of the mothers of children with enuresis also suffered from enuresis when they were children. Conversely, if both parents have a history of enuresis, 40% of their sons will suffer from enuresis and 25% of their daughters will also suffer from this disease.

2. Delayed bladder maturation

Some children with enuresis tend to have smaller bladders than normal children. These children urinate relatively more frequently but not in large amounts. This is because there is not much urine in the bladder, so it contracts and urinates.

3. Disease Factors

It is uncommon for enuresis to be caused by organic diseases. Urinary tract infections, deformities, spina bifida, meningocele, etc. can cause enuresis. In addition, asymptomatic bacteriuria and hypercalciuria can also cause enuresis and should attract people's attention.

4. Sleeping too deeply

This is a more common factor. These children often play until they are tired before going to bed, sleep very deeply, are difficult to wake up, and often wet the bed in their dreams. If you drink more water before going to bed, you are more likely to wet the bed.

5. According to the clinical characteristics of primary enuresis, the disease can be divided into the following types:

Diurnal and nocturnal urinary frequency type: frequent urination at night, often >1 time, accompanied by daytime urinary frequency. The pathological mechanism is the disorder of bladder urination function regulation.

Arousal disorder type: Arousal disorder is prominent, and there is no frequent urination during the day. The pathological mechanism is the disorder of nerve conduction function regulation.

Nocturnal polyuria: The amount of urine is large at night, but the frequency of bedwetting is not frequent, and there is no frequent urination during the day. The pathological mechanism is the disorder of nocturnal antidiuretic hormone secretion function.

Hybrid:

1. Frequent urination during the day and night + awakening disorder;

2. Frequent urination during the day and night + polyuria at night; 3. Arousal disorder + polyuria at night.

Enuresis can cause harm such as decreased immunity, impaired reproductive function, damaged gastrointestinal system, psychological problems, and decreased intelligence.
