1. Introduction
This guidance supports clinicians in the prevention and management of constipation in children and young people with the following actions:
- providing a clear and standardised approach based on guidelines from the National Institute for Health and Care Excellence (NICE), the British National Formulary for Children (BNFc) and clinical expert groups
- ensuring that resources for clinicians, families and other care providers are easily accessible
- promoting available resources for clinicians, families and other care providers
- raising the profile of constipation in children and young people with a learning disability as a factor in adult mortality rates
- recommending standardised Systematized Nomenclature of Medicine (SNOMED) codes for constipation in electronic documentation:
SNOMED code | Term |
14760008 |
Constipation |
236069009 |
Chronic constipation |
31499008 |
Chronic constipation with overflow |
Note: NICE guidelines define chronic constipation as “symptoms lasting more than 3 months”.
2. Constipation pathway for primary care
Constipation pathway:
Child presents with constipation or soiling (faecal incontinence)
- Undertake assessment and eliminate red flags.
- If signs of faecal impaction present, follow ‘child presents with faecal impaction’. If no signs of faecal impaction present, follow ‘child presents with constipation’.
Child presents with faecal impaction
- Disimpact as per NICE guidelines. Review within 1 week.
- Ensure that parents know how to give macrogols (instruct to mix each sachet in 62mls of water for paediatric strength and 125mls for adult strength sachets)
- Macrogols should be used in all children including those under 2 as per NICE and BNFc.
- Do not assume soiling is part of underlying condition in children with disabilities.
- When impaction cleared treat as per child with constipation. If no improvement, see below.
- For more see principles of management for primary care and principles of management when a child presents in hospital.
Child presents with constipation
- Patient not impacted or has completed disimpaction: commence maintenance laxatives as per NICE Review in 2 weeks.
- Ensure that parents know how to give macrogols (instruct to mix each sachet in 62mls of water for paediatric strength and 125mls for adult strength sachets).
- Macrogols should be used in all children including those under 2 as per NICE and BNFc.
- Do not assume soiling is part of underlying condition in children with disabilities.
For further guidance on when a child presents with faecal impaction or constipation, see principles of management for primary care and principles of management when a child presents in hospital.
No Improvement
- No Improvement within two weeks of starting disimpaction or at review for maintenance, when on macrogols alone.
- Add a stimulant laxative such as sodium picosulfate as per NICE Guidance and BNFc.
- Review in 2 weeks.
No improvement after disimpaction or within three months of starting treatment
- No improvement after disimpaction or within three months of starting treatment, complex child or other concerns, refer to local community nurse-led children’s bladder and bowel service and continue to provide support.
Improved
Continue successful maintenance medication until regular bowel habit and toilet training established and symptom free. Ensure laxatives put onto repeat prescription. Review as required. Do not stop laxatives abruptly.
Improvement sustained
Reduce medication gradually, as tolerated. This will take weeks or months for chronic constipation.
Points to consider:
All families: safeguarding should be considered and managed as per local safeguarding procedures.
Resources for providing written and verbal information to family
Consider behavioural modification, toileting regimes, physical activity, diet and fluids as treatment adjuncts.
Red flags – for immediate referral to paediatrician
- symptoms that commence from birth or in the first few weeks
- failure or delay (>first 48 hours at term) in passing meconium
- ribbon stools, leg weakness or locomotor delay
- abdominal distension with vomiting
- abnormal examination findings including:
- abnormal appearance of anus
- gross abdominal distension
- abnormal gluteal muscles, scoliosis, sacral agenesis, discoloured skin, naevi or sinus, hairy patch, or central pit
- lower limb deformity including talipes
- abnormal lower limb reflexes or neuromuscular signs unexplained by existing conditions
- other symptoms that cause concern.

Principles of management for primary care (as per NICE guidance and quality standards)
- Laxatives are always first line management of acute or chronic constipation in children. The aim is to titrate doses to ensure the passage of soft, pain free stools and to overcome any withholding behaviours.
- Do not use diet and fluids alone as treatment. Diet and fluid adjustments do not break down hard faeces and there is evidence that constipation is unrelated to diet and fluid intake in about 59% of affected children.
- When constipation has persisted for more than four weeks it is considered chronic. Resolution can take six months or more if the child has developed mega-rectum or mega-colon. Maintenance doses of laxatives for chronic constipation should be continued for at least three to six months after symptoms resolve and toilet training is established unless loose stools develop. They should then be slowly and cautiously titrated down as the child tolerates. The aim is to prevent relapse.
- Children with disabilities are more prone to constipation than their typically developing peers. It must be treated proactively to prevent long-term morbidities and potential mortality in the young person or young adult with a learning disability.
- Treatment of constipation in children with disabilities should follow the same pathway. If there are complex needs, safeguarding concerns, or there is no or limited progress, consider early onward referral to specialist bladder and bowel service.
- Continued provision of prescriptions for laxatives is essential to allow the bowel to recover and prevent withholding due to fear of painful bowel actions.
- Laxatives should not be stopped abruptly.
- Acute constipation (history of less than four weeks) often needs proactive ongoing, preventative treatment so that it does not become chronic due to pain on bowel opening resulting in fear and withholding.
- If stools are too loose with macrogol alone, or if macrogol alone is insufficiently effective, add a stimulant laxative (sodium picosulfate or senna). Start with a lower dose and titrate upwards until desired effect achieved.
- Do not use rectal interventions as first line treatment. If rectal interventions are indicated these should be prescribed under the guidance of a specialist nurse or paediatrician.
- Regular follow up improves outcomes. Family should be contacted one week after commencing disimpaction, two weeks after commencing maintenance, then within a further four weeks and then within eight weeks. Further follow up should continue as appropriate to the child and family.
- If no improvement within four weeks in children under one year, refer urgently to a paediatrician.
- If no or limited improvement after three months, in children over one year old, or additional concerns refer to specialist service.
- If soiling resumes, consider if over or under treated and consider referral to specialist service.
- Consider involving other members of the multidisciplinary team as appropriate.
Assessment including physical examination
- Diagnosis is largely based on history: ask about frequency and size of bowel actions, consistency of stools, soiling (in toilet trained child), pain with bowel actions, bleeding or mucous passed with stools, retentive posturing (usually straight legs, tiptoe and back arched or hiding to defecate), straining, abdominal distension or pain, appetite and fluid intake.
- Ask about previous history, including onset of symptoms, precipitating factors, passage of meconium, growth and general wellbeing.
- Physical examination: to exclude red flags, as per NICE recommendations. Include inspection of perianal area for appearance, position and patency; abdominal examination, inspection of spine/lumbosacral and gluteal regions; lower limb neuromuscular examination including tone and strength. If any red flags in history or examination suggest new onset neurological impairment check lower limb reflexes.
- If not trained to examine do not delay treatment. If not making expected progress with treatment, refer to paediatrician for examination and specialist intervention.
- If faltering growth treat constipation and check for coeliac and hypothyroidism.
- Do not undertake digital rectal examination unless competent to interpret features of anatomical abnormality or Hirschsprung’s disease.
Disimpaction guide for primary care
- Treatment involves clearing out all retained faeces through administration of escalating doses of laxatives. Macrogols are used as first line unless contraindicated.

- Advise the family on how to mix and administer macrogols (understanding macrogol laxatives) and how to prepare macrogol laxatives.
- Advise the family to continue on the above regime until the child is passing type 7 stools with no lumps of faeces present, although there may be ‘bits’ from undigested food. Explain that this usually takes 5-7 days, but may take longer.
- If disimpaction is not complete within fourteen days of starting the above regime, or if macrogols are not tolerated or not taken by the child, add a stimulant laxative as per BNFc. Consider starting on low doses and titrating up to avoid excess abdominal pain. Children who are on a stimulant laxative only may benefit from the addition of an osmotic laxative such as lactulose or docusate.

Maintenance guide for primary care
- First line treatment of all idiopathic constipation in children is with laxatives, usually macrogols. Prompt treatment may prevent constipation becoming chronic.
- Chronic constipation requires long-term treatment to overcome fear of painful defecation and subsequent withholding and establishment of toilet training in younger children.
- Many children require laxatives for months.
- Ensure parents know how to mix and administer macrogols (understanding macrogol laxatives and how to prepare macrogol laxatives).
- Adjust laxative dose according to response. Consider adding stimulants if macrogols insufficiently effective, not tolerated or refused by the child. Children who are on a stimulant laxative only may benefit from the addition of an osmotic laxative such as lactulose or docusate.
- Continue laxatives at dose required to maintain soft bowel motions for at least three to six months. Reduce doses cautiously over a long time period if initial constipation had persisted for more than four weeks.

4. Principles of management when child presents in hospital
Children should NOT attend A&E for treatment of constipation UNLESS acutely unwell:
- increasing abdominal pain
- increasing abdominal distention
- vomiting, unable to tolerate oral fluids
- reduced urine output
- Child may present to A&E or be diagnosed during an in-patient stay.
- Assess child to rule out an urgent medical emergency.
- Complete assessment to confirm diagnosis of constipation.
- Explain diagnosis to family including correct treatment pathway – ie in primary care.
- Provide information using varied media – printed, by sending a link to parent’s mobile and by showing QR code.
- Give sufficient Macrogol laxatives to last 1/52 (unless they already have a supply at home).
- Refer to GP, emphasizing that the child must be reviewed within 1/52 to monitor progress with disimpaction and prescribe more laxatives.
- Do not routinely prescribe PR interventions in A&E.
- Indication for PR intervention – distressed child, in significant pain, unable to pass any stool.
- Consider Sodium Citrate micro-enema/Bisacodyl suppository as first line PR treatment.
- Consider Phosphate enema if Sodium Citrate/Bisacodyl ineffective, titrating dose according to age and considering dilution.
- PR medication to be cautiously administered in A&E department. Child to be observed to ensure effective result, pain settled and clinical urgency resolved.
- If yes, child to be discharged home with disimpaction information, oral laxatives and referral to GP as above.
- If no, child to be admitted.
- If admission is deemed necessary, constipation management may include:
- Administration of macrogol laxatives via nasogastric tube; stimulant laxatives added as required.
- Kleen prep or Picolax may be prescribed if macrogol laxatives + stimulants + enemas/suppositories are not effective.
- Manual evacuation should only be used as a last resort, and must always be performed under general anaesthetic and with guidance from a paediatrician/paediatric surgeon.
