Post-Infectious IBS Recovery: Practical Steps

Improve Gut Health Editorial Team • Jan 26, 2026 • 6 min read

IBS symptoms after an infection can persist. A structured, evidence-informed plan helps restore function and comfort.

Quick answer

Post-infectious IBS (PI-IBS) often improves with time and a targeted approach that addresses lingering inflammation, motility, and diet. Start with a simple baseline and a short, structured trial of targeted therapies as guided by a clinician.

Key steps

  • Ensure infection is fully resolved and assess for persistent symptoms that require medical evaluation.
  • Establish baseline: regular meals, protein at each meal, and gradual fiber as tolerated.
  • Intro a phased gut-healing approach if symptoms persist: hydration, movement, stress management.
  • Consider targeted testing for dysbiosis or small intestinal bacterial overgrowth if symptoms linger beyond 4-8 weeks.

Practical plan

  • Meal timing: eat at consistent times to support motility.
  • Fiber: start with soluble fiber, monitor tolerance.
  • Hydration and physical activity: modest daily movement supports transit.
  • Reassess symptoms after 2-4 weeks and adjust plan with clinician guidance.
