Encopresis is the repeated passing of stool into inappropriate places, like underwear, in children age four or older. It affects roughly 4% of five- and six-year-olds in the United States, dropping to about 1.6% by ages 11 to 12. Despite how alarming it can be for parents, encopresis is almost always tied to chronic constipation and is treatable with a combination of medical and behavioral approaches.
How Constipation Leads to Soiling
About nine out of ten children with encopresis have what’s called the “retentive” type, meaning the underlying problem is a buildup of hard stool in the colon. Understanding the chain of events helps explain why a child who seems to be having accidents isn’t doing it on purpose.
When a child holds in stool repeatedly, whether because of pain, fear, or simply not wanting to stop playing, a large mass of hard stool accumulates in the rectum. Over time, the colon stretches to accommodate it. That stretching dulls the nerves that normally signal “it’s time to go,” so the child gradually loses the ability to feel when they need a bowel movement. Meanwhile, softer or liquid stool higher up in the colon seeps around the blockage and leaks out, staining underwear. The child often has no idea it’s happening. To a parent, it looks like diarrhea or laziness, but it’s actually overflow leakage around a mass of impacted stool.
Children caught in this cycle often resort to “retentive posturing,” clenching their buttocks and squeezing their legs together. Parents sometimes mistake this for straining to go, when the child is actually trying not to go because passing the large, hard stool has become painful.
Non-Retentive Encopresis
The remaining roughly 10% of children with encopresis don’t have constipation at all. These children typically have daily bowel movements, show no signs of stool buildup, and don’t complain of constipation. Instead, soiling happens because the rectal lining can’t distinguish between gas and liquid. A child relaxes for a split second to pass gas, and stool leaks out with it. Episodes can range from small smears to a full bowel movement.
In some cases, non-retentive encopresis is connected to emotional disturbance. Soiling episodes may cluster around a particular person or time of day, sometimes triggered by anger in children with behavioral disorders. This form is diagnosed when a child four or older has inappropriate bowel movements at least once a month for two months or more, with no underlying disease or stool retention to explain it.
Why It Happens in the First Place
The cycle usually starts with something that makes a bowel movement painful or stressful. Common triggers include a bout of hard stool that hurt to pass, a change in diet, starting at a new school, toilet training that was pressured or started too early, or reluctance to use unfamiliar bathrooms. Once a child learns that pooping can hurt, they begin avoiding it. Each day of avoidance makes the retained stool harder and larger, which makes the next attempt more painful, reinforcing the avoidance.
Stress and psychological factors play a role as well. Children with encopresis show higher rates of emotional and behavioral problems compared to their peers. It’s often a chicken-and-egg situation: stress can trigger the constipation that leads to soiling, and the soiling itself creates shame and anxiety that make everything worse.
The Emotional Toll on Children
Encopresis carries a significant social and emotional burden. Children who soil are vulnerable to teasing, exclusion, and deep embarrassment. They may avoid sleepovers, field trips, or any situation where an accident could be discovered. Research consistently shows that children dealing with constipation and soiling together tend to have the highest levels of psychosocial problems, including low self-esteem, withdrawal, and behavioral difficulties.
These emotional struggles aren’t just a side effect. They can actively interfere with treatment. A child who feels ashamed may hide soiled underwear instead of telling a parent, or resist sitting on the toilet because the whole topic feels loaded with failure. Addressing the emotional side early, whether through reassurance at home or professional support, can improve how well the child responds to treatment overall.
How Treatment Works
For the retentive type, treatment happens in two phases. The first step is clearing the impacted stool from the colon, sometimes called a “clean-out.” This is done using laxatives, suppositories, or enemas, depending on how severe the blockage is. The second phase is maintenance: keeping stools soft and regular long enough for the stretched colon to return to its normal size and for the child’s rectal nerves to regain sensitivity. This maintenance phase typically involves continued use of stool softeners or mild laxatives, which are gradually reduced as bowel function normalizes.
Diet matters during this process. Increasing fiber through whole grain breads (look for at least 4 grams of fiber per slice), fruits, and vegetables helps keep stool soft. Adequate fluid intake is equally important, though the right amount varies by a child’s age and weight.
Behavioral Strategies
Medical treatment alone often isn’t enough. Behavioral approaches are a core part of the plan. The most effective technique is scheduled toilet sits: having your child sit on the toilet at the same times each day, typically after meals when the body’s natural digestive reflexes are strongest. Sits should last about five to ten minutes and happen whether or not the child feels the urge to go. The goal is to rebuild the habit of regular, relaxed toileting.
Positive reinforcement makes a measurable difference. One well-documented approach uses a token system where children earn small rewards simply for completing their scheduled sits, not just for producing a bowel movement. This removes the pressure of “performing” and helps the child associate the toilet with positive experiences. Over time, once regular sitting is established, rewards can shift to also include successful bowel movements. Consequences for accidents should be matter-of-fact, like helping with clean-up, rather than punitive.
What Recovery Looks Like
Encopresis is not a quick fix. Parents should expect treatment to take months, and setbacks are normal. A long-term follow-up study of 45 children found that at an average of about four and a half years after treatment, 58% were in complete remission, 29% had improved significantly, and 13% showed no improvement. Notably, children who had been out of treatment longer were more likely to be in remission, suggesting that the chances of full recovery increase with time.
The maintenance phase of treatment, keeping stools soft and sticking with scheduled sits, often needs to continue for six months or longer. Stopping laxatives too early is one of the most common reasons for relapse. The colon needs time to shrink back to its normal size, and the nerves need time to recover their sensitivity.
What Happens Without Treatment
Left untreated, encopresis can become a chronic problem that extends well beyond childhood. Physical complications include long-term constipation that becomes increasingly difficult to manage, loss of bladder control (because the distended colon presses on the bladder), and urinary tract infections. The social consequences can be equally damaging. Persistent soiling through the school years puts children at serious risk for bullying, social isolation, and lasting harm to self-confidence.
The global prevalence of encopresis ranges from 0.8% to 7.8% depending on how it’s measured, which means a fair number of children are affected but many never receive treatment. Because children are often too embarrassed to bring it up, and because parents may assume the child is simply being careless, the condition frequently goes unaddressed far longer than it needs to.
