What is bedwetting?

Bedwetting, or nocturnal enuresis, is a condition that causes your child to urinate in bed while he or she sleeps. The condition occurs in children who are 5 years or older. Your child may wet the bed at least 2 times each week. He or she may never have had a dry night. He or she may have dry nights for at least 6 months and then begin to wet the bed again.

What causes bedwetting?

The exact cause of your child's bedwetting may not be known. Any of the following can cause bedwetting:

  • A small bladder
  • Bladder tightening before the bladder is full, causing leakage
  • Large amounts of urine made while your child sleeps
  • Deep sleep that keeps your child from waking to the feeling of a full bladder

What increases my child's risk for bedwetting?

  • Drinking a lot of liquid before bed
  • A medical condition such as constipation or a urinary tract infection (UTI)
  • Family history of bedwetting
  • Attention deficit hyperactivity disorder (ADHD)
  • Increased stress such as moving to a new home or the birth of a new sibling

How is bedwetting diagnosed?

Your child's healthcare provider will ask when your child started to wet the bed and how often it happens. The provider will check your child's abdomen, spine, and genitals. Your child's provider will ask if your child wets himself or herself during the day. Your child may need any of the following:

  • A urine test may show infection or dehydration.
  • A blood test may show organ function and sugar levels.
  • An ultrasound or cystoscopy may be needed to look at your child's urinary tract. Ask your child's healthcare provider for more information about these tests.

How is bedwetting treated?

  • A bedwetting alarm can be used to wake your child if he or she begins to urinate during the night. Use the alarm for at least 2 months, or until your child is dry for 14 nights in a row.
  • Pelvic muscle exercises are used to help strengthen pelvic muscles. The exercises will help improve bladder control.
  • Medicines can help your child's bladder hold more urine, or decrease the amount of urine made at night.
