Objectives: Irritable Bowel Syndrome (IBS) presents with diverse symptomatology influenced by individual traits, necessitating a comprehensive understanding of contributing factors. This study aimed to delineate the features of IBS symptom severity in Korean patients, employing the Irritable Bowel Syndrome Severity Scoring System (IBS-SSS) and exploring associated factors.

Methods: Conducted through online surveys, the study recruited 239 Korean adults aged 20-64, adhering to ROME IV criteria. Survey domains encompassed demographics, IBS symptom severity assessed via the IBS-SSS, and dietary habits assessed using a Food Frequency Questionnaire (FFQ). Symptom severity was graded on a scale of 0 to 500, categorized as mild (75-174), moderate (175-299), or severe (≥300). Statistical analyses, including cross-analysis, ANOVA, and post-hoc tests, were performed using SPSS version 26.0, with a significance level set at p< 0.05.

Results: Results revealed that among the participants, 100 (41.9%) had mild symptoms, 104 (43.5%) had moderate symptoms, and 35 (14.6%) had severe symptoms. Factors showing significant differences according to symptom severity included stress (p < 0.001), stool form (p=0.049), and experience of nutrition education or dietary therapy (p=0.001). Although overall FODMAPs intake did not exhibit significant differences, age-stratified analysis revealed variations in fructan intake according to symptom severity. Notably, among individuals aged 30-49, fructan intake was 3.33±2.36 g (mild)(a), 4.80±3.75 g (moderate)(b), and 4.53±2.76 g (severe)(ab), respectively (p < 0.03).

Conclusions: These findings underscore the multifactorial nature of symptom severity in IBS and emphasize the need for personalized management strategies considering factors such as stress, nutrition education, and dietary intake.
