Constipation Treatment in Adolescents

Effectiveness and Appropriateness for Adolescents

  • The American Gastroenterological Association recommends that psyllium-containing compounds like Metamucil are unlikely to effectively control constipation and are not recommended as primary treatment, particularly when other more effective options are available 1, 3
  • For adolescents with constipation, stimulant laxatives or osmotic laxatives are generally more effective and appropriate 2, 4

Better Treatment Options for Adolescent Constipation

  • The National Comprehensive Cancer Network recommends that osmotic laxatives (polyethylene glycol, lactulose, magnesium salts) or stimulant laxatives (senna, bisacodyl) should be considered as first-line pharmacological treatments 5, 4
  • Polyethylene glycol (PEG) is particularly effective and well-tolerated in younger populations 4
  • Stimulant laxatives like senna or bisacodyl are more effective than fiber supplements for treating constipation 2, 5

Non-Pharmacological Approaches to Consider First

  • Increased dietary fiber through natural food sources rather than supplements 2, 4
  • Adequate fluid intake and regular physical activity 1, 2
  • Establishing regular toilet habits and time for defecation 2
