Bedwetting issues?


My daughter is 8 years old and has been bedwetting almost every night.
I've observed that whenever she bends her legs backward while sleeping, it indicates she needs to urinate.
However, she does not wake up on her own; she either needs to be called to get up or will only wake up after wetting her underwear, but she has no memory of it the next day.
She also has a constipation issue and takes a stool softener (Sennoside A+B & Magnesium Oxide) daily.
Could her long-term use of stool softeners be contributing to this problem? During the day, she often holds her urine, fidgets, and cannot sit still, but she claims she doesn't feel the urge until it's very urgent.
Could this be due to her central nervous system not being fully developed? If we need to see a doctor, should we consult a pediatric urologist? Thank you for your response, doctor!

The definition of bedwetting refers to the involuntary urination that occurs during sleep in children older than 5 or 6 years.
Therefore, your child is experiencing bedwetting.
The primary cause is often due to the immaturity of the central nervous system, which typically improves with age.
However, it is essential to rule out other secondary factors, such as childhood diabetes, diabetes insipidus, urinary tract infections, urinary system structural abnormalities, and severe constipation (which will not improve with laxatives).
Therefore, it is recommended to consult a pediatric nephrologist at a major hospital for further evaluation.

More Info


Bedwetting, or nocturnal enuresis, is a common issue among children, particularly those around the age of 8. It can be a source of embarrassment and frustration for both the child and the parents. Understanding the causes and potential solutions can help alleviate this problem.


Causes of Bedwetting
1. Developmental Factors: Many children experience bedwetting because their bladder control is still developing. The central nervous system, which helps regulate bladder function, may not be fully mature, leading to difficulties in waking up when the bladder is full.

2. Genetics: There is often a familial pattern to bedwetting. If one or both parents experienced bedwetting as children, their offspring may be more likely to experience it as well.

3. Deep Sleep: Some children are deep sleepers and may not wake up when they need to urinate. This can lead to bedwetting, as they may not be aware of the sensation of a full bladder.

4. Constipation: As you mentioned, your daughter has a history of constipation and is taking softeners. Constipation can put pressure on the bladder, reducing its capacity and leading to involuntary urination during sleep. The rectum and bladder are located close to each other, and a full rectum can interfere with bladder function.

5. Psychological Factors: Stressful events, such as changes in the family environment, starting school, or other significant life changes, can trigger or exacerbate bedwetting.

6. Medical Conditions: In some cases, underlying medical issues such as urinary tract infections, diabetes, or abnormalities in the urinary tract can contribute to bedwetting.


Solutions for Bedwetting
1. Behavioral Techniques: Establishing a routine can help. Encourage your daughter to use the bathroom before bedtime and limit fluid intake in the evening. A reward system for dry nights can also be motivating.

2. Bladder Training: During the day, encourage her to hold her urine for longer periods to help increase bladder capacity. This can be done gradually by extending the time between bathroom visits.

3. Nighttime Waking: You can set an alarm to wake her up during the night to use the bathroom. This can help her become more aware of her body's signals.

4. Addressing Constipation: Since your daughter is experiencing constipation, it’s crucial to manage this issue effectively. Ensure she has a diet rich in fiber, adequate hydration, and regular physical activity. Consult with a pediatrician about the long-term use of softeners and explore other dietary adjustments.

5. Medical Evaluation: If bedwetting persists despite these interventions, or if you notice any other concerning symptoms, it may be beneficial to consult a pediatric urologist. They can evaluate for any underlying medical conditions and provide specialized treatment options.

6. Support and Reassurance: It’s essential to provide emotional support to your daughter. Bedwetting can be distressing, and children often feel embarrassed. Reassure her that this is a common issue and that she is not alone.


Conclusion
Bedwetting is a multifaceted issue that can stem from various causes, including developmental delays, genetic factors, and constipation. By addressing the underlying issues, such as constipation, and implementing behavioral strategies, many children can overcome bedwetting. If the problem persists, seeking medical advice is a prudent step to ensure there are no underlying health concerns. Remember, patience and understanding are key as your daughter navigates this challenge.
