The Psychological Causes of Bedwetting

This piece has been medically reviewed by Samantha Eaker DNP, CPNP-PC, Medical Advisor to Aeroflow Urology.

The physical causes of primary and secondary nocturnal enuresis vary from child to adult.

In your child, the causes for bedwetting may include:

• Constipation. A 2018 study revealed that about 32 percent of children and adolescents are constipated, and when your child is constipated, it can lead to NE for two reasons. The first is that when your child’s rectum is full, it can reduce the amount of urine their bladder can hold. The second is that full bowels can mix up nerve signals from the bladder to the brain. This can contribute not only to bedwetting, but also daytime urinary symptoms such as daytime incontinence (wetting), urgency, frequency, and urinary tract infections (UTIs).
• Genetics. There seems to be a link between children who wet the bed and parents who wet the bed when they were young. Seventy-seven percent of children whose parents experienced NE wet the bed. So, if you wet the bed when you were younger, it’s more likely your child will, too.
• Bladder size. If your child wets the bed, it may be due to their bladder capacity. Some children have smaller bladder sizes, leading to less room to hold urine at night and less bladder control.
• Medical conditions. Children who wet the bed sometimes have correlated with and associated with medical conditions, such as sleep apnea, diabetes, incontinence, sickle cell disease, UTIs, and attention deficit hyperactivity disorder (ADHD).
• Neurological conditions. Seizure disorders, multiple sclerosis (MS), and Parkinson’s disease have been linked to bedwetting due to impaired bladder control.
• Basic arousal from sleep. For many children who experience bedwetting, the underlying cause is simply that they are heavy sleepers and do not wake up easily at night.
• Hormone imbalance. The antidiuretic hormone (ADH), also known as vasopressin, controls how much urine the body makes at night. ADH tells the body to make less during sleep, but if your child’s brain doesn’t produce enough ADH, they will make too much urine as they sleep.

In adults, the physical reasons for nocturnal enuresis may include:

• Genetics. Like children, adults can experience bedwetting due to their family history. Bedwetting can be passed down from generation to generation. If your parent or parents wet the bed, the chances that you will are much higher.
• Hormone imbalance. The same hormone, vasopressin or ADH, controls urine production in adults. If you don’t make enough ADH at night, you may wet the bed.
• Bladder size. Similar to children who wet the bed, adults with smaller bladders may be unable to hold more urine at night and therefore may experience NE.
• Overactive bladder (OAB). If you have OAB, you may be more likely to wet the bed due to your bladder muscles contracting at incorrect times.
• Medical conditions. Adults who have NE sometimes have correlating conditions, such as cancer, UTIs, prostate cancer, enlarged prostate gland, pelvic organ prolapse (in women), bladder cancer, and diabetes (especially among the elderly).
• Neurological conditions. Seizure disorders, multiple sclerosis (MS), and Parkinson’s disease have been linked to adult bedwetting due to impaired bladder control.
• Obstructions. If you experience bedwetting as an adult, it may be due to blockages or obstructions in your urinary tract. Common obstructions include kidney stones, tumors, and bladder stones. These can also cause daytime wetting and incomplete voiding.
• Medications. Some prescriptions taken for insomnia, such as Thioridazine, Clozapine, and Risperidone, can cause bedwetting in adults.
• Bladder irritants. Irritants like caffeine and alcohol can cause bedwetting. Drinking alcohol slows the production of ADH in your body, so when you go to sleep after drinking, your body continues to produce large amounts of urine. Alcohol also irritates the bladder and adds to the amount of fluids that need to be filtered through your body. 
• Sleep problems. If you experience sleep apnea or have a hard time arousing from sleep, you may be more prone to NE.

The physical reasons listed above have been proven to be linked to NE, but what about the non-physical causes of bedwetting?

According to the American Psychological Association, although it is not entirely understood, there is a link between psychological factors and bedwetting in adults and children.

One study found that NE is ranked as the third most distressing life event for children (out of 11), so it makes sense that wetting the bed would be an outcome of these issues. Possible causes include:

• Stress, anxiety, or fear. If your child experiences stress, anxiety, or fear, they may be more prone to wetting the bed. Chronic stressors, such as socioeconomic problems, a family’s financial situation, bullying, and other anxieties, have been linked to bedwetting. When children experience stress, they have a more challenging time falling asleep, leading to sleep deprivation. After being sleep deprived, they go into an even deeper rest where they cannot wake themselves up to use the bathroom.
• Life events. Significant life changes, like moving, divorce, attending a new school, the birth of a new sibling, or a death in the family can cause or worsen NE in your child. When these changes occur, your child’s stress level may rise, resulting in sleep deprivation and bedwetting. One study also found that children prone to stress were more likely to experience NE.
• Child abuse or sexual abuse. The American Academy of Pediatrics revealed that NE could result from sexual abuse in children and teens. Some healthcare professionals believe this is a protective mechanism children may use against their abuser. Still, it may also be an unconscious decision made due to stress and fear. Physical abuse by parents, family members, or caretakers in the home or at a daycare / school may also lead to bedwetting in children. Always take action if you believe your child is being harmed or abused in any way.

• Post-traumatic stress disorder (PTSD). PTSD may develop in children who have experienced physical or sexual abuse or things like car accidents. PTSD can cause bedwetting, fear of falling asleep, or nightmares in children. In addition, reliving the events that cause PTSD can trigger a fight-or-flight response in your child’s body, causing their nerves to become extra sensitive. This can result in the body filling the kidneys with urine and contracting too quickly to make it to the bathroom.
• Night terrors. Sleeping problems like night terrors (possibly due to PTSD) can cause your child to wake up in a panic, causing them to lose control of their bladder and wet the bed.

The psychological aspects of NE are similar in adults to those in children, with a couple of different possibilities. Because adults are unlikely to disclose their bedwetting patterns to healthcare professionals due to shame or embarrassment, there may be less evidence to support the psychological causes. Some of the known reasons in adults include:

• PTSD. No matter what age you are, PTSD can increase the likelihood that you experience bedwetting. NE in veterans is ubiquitous; One study showed that incontinence was three times more likely, including bedwetting, in men who had PTSD from war experiences.
• Life events. It can all contribute to bedwetting if you are starting a new job, having a child, entering into a new relationship, moving into a new house, or losing a loved one. These life changes create stress, making it harder to fall asleep. When you do finally sleep, you may go into a deeper sleep and not wake up to go.
• Unsafe environments. If you live in an environment that feels unsafe, you may experience bedwetting due to stress. An environment in which you are sexually or physically abused is also considered hazardous for adults, which can lead to wetting the bed. If you live in an unsafe situation or experiencing abuse, always get help.
• Stress and anxiety. Emotional problems like stress and anxiety can cause NE. If you experience chronic stress or anxiety, your body enters the fight-or-flight response, which can fill your kidneys with urine while you sleep.

Bedwetting can have a significant impact on the lives of adults and children, whether it’s in the form of low self-esteem, shame, embarrassment, or not being able to participate in certain activities.

The impacts bedwetting can have on children include:

• Emotional and social development issues. If your child wets the bed frequently, they may experience bullying or teasing from family members or peers. This can impact their emotional and social development by causing shame, embarrassment, and fear of participating in sleepovers, family holidays, and certain school activities.
• Low self-esteem. Your child’s self-esteem may be lowered when they wet the bed, which may lead to a cycle of more wet nights. This may be because children who wet the bed report being teased by their family members or peers.

The impacts of bedwetting in adults include:

• Financial strains. It’s estimated that it can cost you up to $1,000 a year to replace bedding that’s damaged during bedwetting.
• Low self-esteem. If you’re experiencing NE, you may feel ashamed and begin to experience low levels of confidence.
• Depression. A study done showed that adults who wet the bed had higher cases of depression and, in turn, were more likely to wet the bed.
• Interruption of daily life. If you experience bedwetting, you may avoid taking specific jobs. You may also see a drop in your performance at work due to waking up in the middle of the night to get dry. You may choose not to participate in activities like staying at other people’s or a partner’s house to avoid a bedwetting incident.

This may help rule out if the cause is a low amount of ADH. Getting an ADH test won’t determine a condition by itself, but it can be helpful for your healthcare provider as they attempt to treat you or your child’s condition.

• Try bedwetting alarms.Bedwetting alarms can work for deep sleepers who experience NE. These are typically thought to be the gold standard treatment for bedwetting. To use bedwetting alarms, you place a sensor in you or your child’s pajamas, and the alarm will sound when it senses moisture. The alarm should wake you or your child up to use the bathroom. However, it can be challenging for individuals who are deep sleepers.
• Talk to a therapist. If you or your child is experiencing PTSD, chronic stress, anxiety, bullying, low self-esteem, physical, or sexual abuse, speak with a professional therapist. You or your child’s mental health should always be a priority. Not only will this help with psychological issues behind bedwetting, but a therapist may also be able to help come up with a plan to stop the NE.
• Ask about medication. Sometimes your healthcare provider may prescribe desmopressin or imipramine (for children ages six and up). These medications can lower the amount of urine your kidneys produce and help you or your child sleep through the night.
• Manage stress at home. If stress is the reason behind NE, try managing it at home. Techniques like using positive mantras, stress balls, meditation, and exercise can all help to reduce stress.

• Be supportive. If your child is experiencing bedwetting, be supportive of them and encourage them. Let them know they are not alone by explaining how common bedwetting is among children. You can also help them by reaffirming their behavior when they wake up wet, such as telling them they were brave to come and get you for help.
• Use the bathroom at night.Before bedtime, you should use the bathroom to ensure you void your urine completely before sleep. It is recommended to double-pee (pee, do something for 2-5 minutes, than pee again) before bed if possible. This may help decrease the amount that builds up during the night.
• Alter your diet and fluid intake. Limit the amount of fluids you or your child has before bed and reduce your caffeine and alcohol intake as to limiting bladder irritants may reduce the risk of wetting overnight.
• Try bladder therapy. Speak with a healthcare professional to see how you can retrain your bladder to hold more urine during the night.
• See a sleep specialist. If you experience heavy sleep or sleep apnea, see a specialist. They may use continuous airway pressure therapy to treat sleep apnea.
• Talk with your healthcare provider about surgery. If you experience incontinence and NE, surgery may be an option for you. Sacral nerve stimulation, detrusor myectomy, pelvic organ prolapse repair, and bladder augmentation may help.
