IBS vs Diverticular Disease: When Structural Changes Explain Your Symptoms
Diverticulosis is present in roughly 60 percent of people over age 60, and symptomatic diverticular disease causes abdominal pain, bloating, and altered bowel habits that overlap with IBS. Distinguishing between the two matters because diverticulitis complications (abscess, perforation, stricture) require specific management. CT imaging can identify diverticular disease that colonoscopy alone may undercharacterize.
Current Consensus
- Diverticulosis prevalence increases with age, affecting roughly 60 percent of people over 60.
- Symptomatic uncomplicated diverticular disease (SUDD) causes chronic or recurrent abdominal pain and bloating that mimics IBS.
- CT scan is the primary imaging modality for acute diverticulitis and can identify chronic diverticular changes.
- Left lower quadrant pain is more suggestive of diverticular disease, while IBS pain location is typically more diffuse.
- Post-diverticulitis IBS is a recognized entity where functional symptoms persist after inflammatory resolution.
Open Questions
- Whether SUDD and IBS are distinct conditions or overlapping presentations of visceral hypersensitivity.
- Optimal management of chronic symptoms in patients with both diverticulosis and IBS criteria.
- The role of the microbiome in diverticular disease pathogenesis and symptom generation.
- Whether mesalamine or other anti-inflammatory agents have a role in SUDD.
- How to differentiate post-diverticulitis IBS from ongoing subclinical inflammation.

Can Diverticular Disease Be Misdiagnosed as IBS? When Structural Changes Explain Your Symptoms
Diverticulosis found on colonoscopy is often dismissed while symptoms are attributed to IBS. Learn about SUDD vs IBS overlap, age factors, and when imaging matters.
Testing for Diverticular Disease When IBS Treatment Is Not Working
If IBS treatments are not helping, diverticular disease may be the cause. Learn about CT imaging, colonoscopy findings, the fiber debate, and when to seek urgent care.
