Key facts

Encopresis at a glance.

The essentials, in plain English - what it is, the two types, and how UK paediatric teams treat it.

  • What it is

    Involuntary passage of stool in inappropriate places in a child aged 4 or over, at least once a month for three months.

  • How common

    Around 1 to 4 per cent of school-age children - boys affected roughly three times more often than girls.

  • Two types

    Retentive (80 to 95 per cent) - overflow around impacted stool. Non-retentive - behavioural, emotional or safeguarding-related.

  • Main driver

    Chronic constipation with a distended rectum and reduced sensation - not laziness, not naughtiness.

  • Foundation therapy

    Disimpaction with Movicol Paediatric, then long maintenance, plus a non-punitive toileting plan.

  • When to escalate

    Non-retentive soiling, safeguarding concerns, refractory disease or red flags need paediatric specialist input.

Why this guide matters

A stepped plan, not a battle at the toilet.

Encopresis is common, treatable and - with the right plan - usually resolvable. Three points shape everything else on this page.

  • De-stigmatise first

    Explain, reassure and remove blame. A punitive approach entrenches the problem - a calm, non-judgemental plan does the opposite.

  • Treat the constipation properly

    For retentive encopresis, disimpaction followed by long maintenance with Movicol Paediatric is the foundation. Stopping too soon causes relapse.

  • Escalate when the picture fits

    Non-retentive soiling, safeguarding concerns or refractory disease need paediatric gastroenterology, psychology or CAMHS input.

How the diagnosis is made

From first conversation to a clear plan.

The steps a UK GP or paediatrician will normally follow, in order - so you know what to expect and why.

  1. 01

    Assessing

    Careful, non-judgemental history

    Toilet training, stool pattern, painful stools, diet, fluids, school transitions and family stress - the story does most of the work.

  2. 02

    Assessing

    Safeguarding assessment

    Especially with non-retentive soiling - emotional wellbeing, family context and any concerns must be considered carefully.

  3. 03

    Assessing

    Examination

    Abdomen for a palpable faecal mass, spine and neurology, growth and perianal inspection. PR examination is usually deferred to a specialist.

  4. 04

    Confirming

    Selective investigations

    Coeliac serology, thyroid function and calcium if the picture is atypical - abdominal x-ray is not needed routinely per NICE CG99.

  5. 05

    Confirming

    Rule out organic causes

    Hirschsprung disease, spinal dysraphism, cow milk protein allergy, coeliac and hypothyroidism are rare but important to consider.

  6. 06

    Planning

    Paediatric referral if needed

    Refractory disease, non-retentive soiling, safeguarding red flags or suspected organic cause warrant paediatric gastroenterology or psychiatry.

  7. 07

    Planning

    Shared, written plan

    A clear disimpaction and maintenance plan, plus a school and family strategy - agreed with the child where age appropriate.

Typical timeline: a first appointment to a settled maintenance plan in weeks - full resolution over months.

Symptoms

What encopresis actually looks like.

The classic mix of soiling, withholding, hard stools and pain - and the features that mean it is time to escalate.

  • Soiling and underwear stains

    Often mistaken for diarrhoea - it is usually overflow around impacted stool in retentive encopresis.

  • Infrequent, large hard stools

    Passing very large or painful stools every few days - a hallmark of retentive constipation.

  • Abdominal pain and bloating

    Recurrent tummy ache, sometimes with reduced appetite and irritability that eases after passing stool.

  • Palpable faecal loading

    A firm, sometimes tender mass in the lower abdomen - a common examination finding.

  • Anal fissure and PR bleeding

    Fresh red blood on the paper or nappy from a fissure caused by hard stool - painful and self-perpetuating.

  • Withholding behaviour

    Crossing legs, tiptoeing, hiding, refusing the toilet - a fear-driven response to a previous painful stool.

  • Emotional impact

    Shame, low mood, bullying, social withdrawal and family stress - the hidden burden that matters as much as the bowels.

  • Red flag - non-retentive soiling

    Soiling without constipation, or with behavioural, emotional or safeguarding concerns - needs specialist assessment.

Treatment

How encopresis is treated in the UK.

De-stigmatise, disimpact, maintain and behavioural care - with psychological input and specialist support when needed.

  • De-stigmatise and educate

    The first step is always to explain that this is common, not the child's fault, and treatable - and to agree a non-punitive approach.

  • Disimpaction with Movicol

    High-dose Movicol Paediatric, escalating over one to two weeks per NICE CG99 - the essential first step in retentive encopresis.

  • Maintenance laxative

    Daily Movicol Paediatric at a lower dose for months, then very gradual reduction - stopping too early is the commonest cause of relapse.

  • Stimulant laxatives

    Senna, sodium picosulphate or bisacodyl added when osmotic laxatives alone are not enough - specialist advice for prolonged use.

  • Behavioural toileting plan

    Sitting on the toilet after meals to use the gastrocolic reflex, with a step stool, timer and reward chart - never punishment.

  • Diet and fluids

    Adequate fibre and fluids, and avoiding excessive constipating foods - a supporting strategy, never a substitute for laxatives.

  • Psychological support

    For non-retentive or refractory cases - paediatric psychology, CBT, family therapy and safeguarding input as needed.

  • Rectal irrigation (Peristeen)

    For severe, refractory retentive disease under specialist paediatric gastroenterology - see our guide to rectal irrigation.

A quiet reminder

This guide is for information, not medical advice.

Your GP or paediatrician knows your child and history and can tell you which parts apply. If in doubt, get seen.

Red flags

When soiling needs urgent attention.

Most encopresis is managed in primary care. These are the situations that are not - and where specialist input is needed.

  • Non-retentive soiling

    Soiling without constipation - always raises questions about emotional wellbeing, behaviour and safeguarding, and needs specialist input.

  • Safeguarding concerns

    Regression, distress, disclosure or family circumstances that raise concern - follow local safeguarding processes urgently.

  • Delayed passage of meconium

    Late passage after birth, chronic severe constipation from infancy or failure to thrive - consider Hirschsprung disease.

  • Neurological signs

    Lower limb weakness, sensory change, gait disturbance or bladder involvement - consider spinal dysraphism or cord tethering.

  • Growth failure or weight loss

    Faltering growth alongside bowel symptoms - consider coeliac disease, hypothyroidism or inflammatory bowel disease.

  • Persistent PR bleeding

    Beyond a simple fissure - warrants specialist review to exclude other causes of bleeding.

  • Refractory disease

    Failure to respond to a properly delivered disimpaction and maintenance plan - refer to paediatric gastroenterology.

  • Severe psychological distress

    Bullying, school refusal, low mood or self-harm ideation - needs urgent CAMHS or paediatric psychology input.

  • Suspected organic cause

    Coeliac serology, thyroid function or calcium abnormality, or clinical features suggesting an underlying disease.

Living with it

A treatable condition, with a clear plan.

Four things that make the biggest difference day to day - non-punitive language, a post-meal toileting routine, patience with maintenance and a supportive plan at school.

A quiet reminder

Consistency beats intensity, every time.

Small, steady habits - kept up for months - do more than a heroic week that does not last.

  1. 01 Language

    Non-punitive, always

    This is not a discipline problem. Praise the effort, not the outcome, and take the shame out of soiling with calm language.

  2. 02 Routine

    Sit after meals

    Ten minutes on the toilet after breakfast and evening meal uses the gastrocolic reflex - with a step stool so feet are supported.

  3. 03 Patience

    Months, not weeks

    Retentive encopresis needs long maintenance treatment. Reducing laxatives too soon is the commonest cause of relapse.

  4. 04 School

    A quiet plan with school

    Reliable toilet access, spare clothes and a supportive named adult make a real difference - ask for reasonable adjustments.

Frequently asked

Everything we get asked about encopresis.

Quick answers on causes, treatment, timelines and when to see a specialist.

  • What is encopresis?

    Encopresis is the involuntary passage of stool in inappropriate places in a child aged four or over who would normally be expected to be toilet-trained. Under Rome IV and DSM-5-TR criteria it happens at least once a month for at least three months. Most cases are retentive - overflow around impacted stool - and around one to four per cent of school-age children are affected.

  • Is my child doing this on purpose?

    No. In retentive encopresis, the rectum is stretched by impacted stool, sensation is reduced and soft stool leaks around it without the child feeling it coming. In non-retentive encopresis there may be emotional, behavioural or safeguarding factors at play - but it is not naughtiness, and a punitive approach makes things worse.

  • What is the difference between retentive and non-retentive encopresis?

    Retentive encopresis - by far the most common form - is caused by chronic constipation with a distended rectum, reduced sensation and overflow soiling. Non-retentive encopresis happens without evidence of constipation and is more likely to be linked to emotional distress, oppositional behaviour, trauma or safeguarding concerns. The two need different treatment plans, which is why careful assessment matters.

  • How is encopresis treated in the UK?

    Per NICE CG99, retentive encopresis is treated in stages - de-stigmatise and educate the family, disimpact with a high-dose escalating course of Movicol Paediatric over one to two weeks, then a long maintenance course of daily Movicol with a behavioural toileting plan and dietary support. Stimulant laxatives, psychological support and specialist paediatric input are added as needed.

  • How long does treatment take?

    Longer than most families expect. Disimpaction usually takes one to two weeks, but maintenance often runs for six to twelve months or more. The rectum needs time to return to a normal size and normal sensation. Stopping laxatives too early is the commonest reason relapse happens - taper slowly, guided by your paediatric team.

  • When should we see a specialist?

    Ask for a paediatric referral if there is non-retentive soiling, safeguarding concerns, refractory disease despite proper treatment, faltering growth, neurological features, delayed passage of meconium as a baby, or significant emotional distress. Rectal irrigation and specialist psychological input are available through paediatric gastroenterology and CAMHS.
