Management Approach for a 20-Month-Old Child with Habitual Constipation

For a 20-month-old child with habitual constipation, implement a stepwise approach starting with increased fluid intake, dietary fiber, and osmotic laxatives as first-line treatment. 1

Initial Assessment and Non-Pharmacological Management

• Rule out organic causes by checking for "red flags" such as delayed passage of meconium, failure to thrive, abdominal distension, or perianal abnormalities 1
• Increase fluid intake to ensure adequate hydration, which is essential for proper stool consistency 2
• Increase dietary fiber intake if the child has adequate fluid intake and physical activity level 2
  • Age-appropriate fiber intake should be approximately age + 5 grams per day 3
  • Introduce fiber-rich foods gradually such as fruits, vegetables, and whole grains 2, 4
• Encourage regular physical activity appropriate for the child's developmental stage 2

Medication Management

• First-line medication: Polyethylene glycol (PEG)

  • Well-tolerated and effective for children with constipation 5
  • For children under 17 years, dosing should be determined by a doctor 6
  • Start with a lower dose and titrate based on response 2

• If constipation persists or is severe:

  • Consider adding a stimulant laxative such as senna or bisacodyl 2
  • Bisacodyl dosing for children: 5-10 mg daily with a goal of one non-forced bowel movement every 1-2 days 2

• For impaction (if present):

  • Consider glycerin suppository for immediate relief 2
  • May require manual disimpaction in severe cases (with appropriate pre-medication) 2

Behavioral Modifications

• Establish a regular toileting routine, encouraging the child to sit on the toilet for 5-10 minutes after meals 2
• Use positive reinforcement for successful bowel movements 4
• Implement a reward system to encourage compliance with dietary changes and toileting behaviors 4
• Monitor bowel movements using a stool diary to track progress 2

Follow-up and Maintenance

• Regular reassessment of constipation symptoms and response to treatment 2
• Continue maintenance therapy for several months as relapse is common (40-50% of children experience at least one relapse in 5 years) 1
• Gradually taper medications once regular bowel habits are established 5
• Continue dietary modifications and adequate fluid intake long-term 3

Common Pitfalls to Avoid

• Inadequate duration of treatment - maintenance therapy often needs to be continued for months to years 5
• Insufficient fiber intake - most children with constipation consume less than one-fourth of recommended fiber 3
• Overreliance on medications without addressing dietary and behavioral components 4
• Discontinuing treatment too early after initial improvement 1
• Failing to provide intensive dietary counseling to families, which is necessary for successful implementation of high-fiber diets 3

Remember that successful management requires consistent implementation of dietary changes, medication when needed, and behavioral modifications, with regular follow-up to adjust the treatment plan as the child grows.
