Post-infectious irritable bowel syndrome after intercontinental travel: a prospective multicentre study 2023

[Andy]

By longitudinally following a large cohort of intercontinental travellers, this study highlights the importance of considering multiple risk factors to comprehend post-infectious Irritable Bowel Syndrome (PI-IBS). Stomach cramps, antibiotic use and nausea during travel were among the variables that predicted PI-IBS development following an episode of traveller’s diarrhoea.

"33 Out of 960 (3.4%) travellers developed IBS without TD [Traveller's Diarrhea] after travel while 65 out of 539 at risk travellers developed PI-IBS (relative risk: 3.51, 95%CI 2.34-5.26, p<0.001). In addition, the majority (78.7%) retained PI-IBS symptoms up to 12 months after travel."

Sadly they don't report on any new diagnoses over the 12 months in this paper. The main study that this data was taken is here, but unfortunately it is paywalled.
