Bedwetting: Facts and Myths

How often have you heard that bedwetting was behavioral or caused by deep sleep and your child would outgrow it? 15% of children per year will “outgrow” bedwetting. What if your child is in the percentile at the end of that range?

Facts:

• Bedwetting affects 15% of girls and 22% of boys
• 5 - 7 Million US children
• Boys are 50% more likely than girls to wet the bed
• 10% of 6 year olds continue to wet
• Spontaneous cure rate 15% per year thereafter
• 1-3% of 18 year olds still wet their beds
• Less than 50% of all bedwetting children have bedwetting alone, without also experiencing daytime urinary leakage or constipation
• Bedwetting is genetic – if one parent was a bed wetter the child has a 40% chance of wetting the bed and if both parents were bedwetters the percentile goes up to 77%

Myths:

• Your child is lazy
• Your child is doing this to get attention
• Your child is just a deep sleeper
• You must wait to grow out of it

Research from the International Children’s Continence Society (ICCS) is a great resource for exploring the research on this topic and other pediatric voiding issues. www.i-c-c-s.org

What causes Bedwetting?

There are many philosophies discussed in the research. Here are some listed below:

1. Hormone deficiency- our bladders empty about every 2-3 hours during the day however at night we can hold over 8 hours! This happens because our bodies produce an antidiuretic hormone when we sleep to slow kidney function and produce less urine to empty into the bladder. If this hormone is not being produced, the kidneys produce as much urine at night as they do during the day. In this case, it's good that the bladder empties out in our sleep, otherwise our bladders would be dangerously large and possibly reflux urine backward into the kidneys. Clearly not behavioral!!
2. Dr. Steven Hodges has researched and written extensively on the topic of constipation causing pressure from the rectum against the bladder making it irritable during sleep. His research has supported the fact that once the bowel is cleaned out daily the bedwetting episodes diminish. See It’s No Accident by Dr. Hodges or visit https://www.bedwettingandaccidents.com for more information on this topic. Again, a physiological cause of bedwetting versus behavioral.
3. Sleep Disturbance and Nasal Airway Obstruction. Dr. Neveus and colleagues reported that 43.5% of children with snoring or obstructive sleep apnea became dry after adenotonsillectomy. Dr. Kovacevic also found increases in antidiuretic hormone seen in responders post-operatively.

Take Home Message

1. Active treatment for bedwetting should begin at age 6
2. The impact of bedwetting is mainly psychological and may be severe
3. Children with bedwetting have abnormal psychological test scores, however once the bedwetting is resolved the test scores return to normal
4. “Treatment is not only justified but mandatory”
