Remission & chronicity

Spontaneous remission
IBS is chronic and remitting; spontaneous 'remission' (symptom resolution without treatment) in ~30-40% at 2 years but symptom recurrence common; 10-20% develop persistent daily symptoms; <10% achieve permanent remission
Best-intervention remission
Low-FODMAP diet: 50-80% symptomatic response; gut-directed hypnotherapy: 70-80% response, durable at 5 years; CBT: 60-70% response; rifaximin for IBS-D: 40% vs 31% placebo (modest but significant); neuromodulators (amitriptyline, nortriptyline): 60-70% response in IBS-D/IBS-M
Gap size
Large — effective interventions exist but access to diet counselling, hypnotherapy, and CBT is limited; overreliance on antispasmodics and antidiarrheals
Primary barrier
access/practice
Gut-directed hypnotherapy has the strongest long-term evidence of any IBS treatment but virtually no trained therapists; FODMAP diet requires skilled dietitian; pharmacotherapy (linaclotide, plecanatide, eluxadoline) effective but expensive; most patients manage with OTC antispasmodics indefinitely
