Area of Science:

  • Gastroenterology
  • Digestive System Diagnostics
  • Intestinal Physiology

Context:

  • Diagnostic procedures for intestinal functions are crucial in gastroenterology.
  • Indications include suspected intestinal motility disturbances and malabsorption syndromes.
  • Current methods like H2 breath tests and D-xylose tests have limitations.

Purpose:

  • To review current diagnostic techniques for intestinal functions.
  • To highlight the role of H2 breath tests and their substrates (lactulose, lactitol, glucose).
  • To introduce emerging 13C breath tests for enhanced diagnostic capabilities.

Summary:

  • H2 breath tests assess orocecal transit time and bacterial overgrowth.
  • Intestinal manometry offers detailed motility analysis but is specialized.
