Similarities between post-COVID and post-infectious Irritable Bowel Syndrome (PI-IBS) suggest that the latter can serve as a useful model for understanding pathophysiological mechanisms and developing therapeutic approaches. Both conditions are functional disorders triggered by an acute infection, with multifactorial etiology and limited biomarker-based diagnostics. The variability of symptoms and the high frequency of comorbidities make these disorders particularly difficult to diagnose. Diagnostic efforts may be further hindered by the stigmatization of such disorders among healthcare providers, the health insurance industry, and the general public. This article explores the parallels between PI-IBS and post-COVID, highlighting, on the one hand, what can be learned from the management of IBS to better address the needs of patients with post-COVID long-term sequelae, and, on the other hand, raising doubts\u2014based on decades of research into drug therapy development for IBS\u2014about the likelihood of a rapidly available treatment for post-COVID.<\/jats:p>","DOI":"10.3389\/fimmu.2026.1717324","type":"journal-article","created":{"date-parts":[[2026,3,16]],"date-time":"2026-03-16T06:39:28Z","timestamp":1773643168000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Lessons
