When to use

  • Diagnosing functional constipation in a child or adolescent (developmental age ≥4 years) without alarm features.
  • Distinguishing functional constipation from organic causes before initiating empiric management.

Formula

Must include ≥2 of: ≤2 defecations/week, ≥1 faecal incontinence episode/week, retentive posturing/stool withholding, painful or hard bowel movements, large faecal mass in rectum, large-diameter stools — occurring at least weekly for ≥1 month, with insufficient criteria for IBS and no other explanation after evaluation.

Pearls and pitfalls

  • Rectal examination and fecal mass are optional but supportive; the diagnosis can be made on history alone.
  • Alarm features (weight loss, bilious vomiting, blood in stool, failure to thrive, late-onset after birth) warrant further work-up before labelling as functional.
