Bedwetting, also called nighttime incontinence or nocturnal enuresis, is involuntary urination while asleep. By the age of 6 years old, 90% of children are able to remain dry overnight. For the other 10%, bedwetting can remain a challenge into their teenage years and beyond.

There are two different types of bedwetting: primary enuresis and secondary enuresis. Primary enuresis is defined as the child never developed nighttime dryness; secondary enuresis is defined as the child had a period of being dry and then started to experience nighttime wetness. Both are common, affecting 5-7 million children throughout the US. It affects roughly 15% of girls and 22% of boys. 

Causes

There are several causes to both types and it’s important to discuss bedwetting with your pediatrician to look for the source: 

A Hormone Imbalance

Our bodies use a hormone called ADH, antidiuretic hormone, to slow the production of urine at night so we can sleep and recover from the day. Insufficient production of this hormone would allow too much urine to be produced at night and could lead to nocturia, which is frequent nighttime urination, or bedwetting. 

Inability to Recognize a Full Bladder

As our bladders fill with urine, it expands. When it expands and stretches enough, nerve endings surrounding it will send a message to our brain to let us know it is time to empty. This sensation can be diminished in children who are not developmentally ready for this milestone or in children who have poor interoception, the perception of sensation from within your body. 

Detrusor Overactivity 

The detrusor is a smooth muscle that forms a layer of the wall of the bladder and contracts when it is time to urinate. If this muscle becomes overactive, it may contract involuntarily, releasing the contents of the bladder at inopportune times. 

Disrupted Sleep Patterns 

The child may have an immature sleep pattern allowing uninhibited reflexive contractions of the bladder, which will improve as the child’s central nervous system matures. The child may also be experiencing sleep apnea, a condition in which a child’s breathing is interrupted during sleep, often due to inflamed or enlarged tonsils or adenoids. 

Constipation 

Fecal matter is stored in the rectum until it is ready to be released. This should occur daily, however, for anyone who is constipated, it may take longer. Although our bladders have a maximum stretch capacity and will automatically empty at a certain point, our rectum can stretch much larger and store poop for days, weeks, months, or even years. As the rectum enlarges, the available space in our pelvis lessens. Eventually, the rectum will begin to push against and increase pressure on the bladder. This can increase both urgency and frequency of urination both during the day and night. 

Stress and anxiety

Stressful events, such as becoming a big brother or sister, starting a new school, sleeping away from home, negative and unwanted attention from adults, may trigger bedwetting. 

Medical diagnoses

Diabetes, kidney disease, sickle cell disease, lumbosacral disorders, anatomical anomalies, and urinary tract infections can all cause bedwetting.

Bedwetting Strategies to Try 

If your child is past the age of 6 and still consistently bedwetting, please speak to your pediatrician about diagnosis and treatment options. In the meantime, here are some simple strategies you can try at home:

  1. If your child has not developed daytime dryness yet, start here. Nighttime dryness usually occurs 10-12 months after consistent daytime dryness. 
  2. Become a detective and look for patterns. Most nighttime leakages occur in the first 4 hours of sleep or 1-2 hours before awakening. After putting your child to sleep, return to their room to check if they’re wet every hour. Continue this for 1-2 weeks to understand the voiding pattern that’s developed. Once you’ve discovered when they consistently leak, wake them up 30 minutes prior to this time and prompt them to void on the toilet. Continue this for a week and after 7 full nights of dryness, decrease the time to awaken by 15-30 minutes after each successful week until full dryness is achieved. 
  3. Avoid common bladder irritants 1-2 hours before bed including: 
    • Milk
    • Carbonated beverages
    • Chocolate 
    • Artificial sweeteners
    • Foods with red or blue dye
    • Acidic foods: tomato-based products, vinegar, tea, curry, citrus fruits, and juices, spicy foods

Pelvic Floor Therapy Can Help

Depending on the cause, pelvic floor therapy may be able to help! Together, we can create a personalized treatment plan that addresses bowel and bladder habits, food and fluid intake, behavior modifications, bedtime routines, clean-up routines, and toileting habits and positioning. It’s important to remember that bedwetting is completely involuntary and no child does this on purpose. For more information, schedule a free consultation with our pelvic floor specialist. With reassurance, support, and understanding, your child can look forward to dry nights!
