Area of Science:

  • Gastroenterology
  • Physiology

Background:

  • Chronic constipation is a common condition with diverse underlying causes.
  • Accurate diagnosis of subtypes is crucial for effective treatment selection.

Purpose of the Study:

  • To outline the physiological basis for chronic constipation subtypes.
  • To guide therapeutic choices based on identified subtypes.

Main Methods:

  • Utilizing the 5-day colonic marker test for transit.
  • Employing anorectal manometry with balloon expulsion testing for pelvic floor function.
  • Defining subtypes by colonic transit, pelvic floor function, and pain.

Main Results:

  • Identified subtypes: slow-transit constipation, pelvic floor dyssynergia, functional constipation, and irritable bowel syndrome with constipation.

  • Significant overlap exists between subtypes, complicating clear distinctions.
  • Symptom severity correlates with reduced quality of life and physical functioning.

    • Conclusions:

    • Physiological testing aids in classifying chronic constipation.
    • Understanding subtypes and their overlap is essential for personalized management.
    • Symptom severity assessment is vital for treatment aggressiveness.
