Background: Anxiety and depressive disorders frequently co-occur, and both are individually associated with gastrointestinal (GI) symptoms. Whether their co-occurrence carries a greater GI symptom burden than either alone has rarely been examined directly within a psychiatric outpatient population.
Objectives: To compare GI symptom burden, assessed by the IBS-SSS and GSRS, among patients with comorbid anxiety and depression, anxiety alone, and depression alone, and to examine whether any difference tracked psychiatric symptom severity.
Methods: A cross-sectional study was conducted in the psychiatry department of SMS Hospital, Jaipur, between March and June 2026. Adults aged 18–60 years with a DSM-5 diagnosis of anxiety only, depression only, or comorbid anxiety and depression were enrolled. Severity was graded with the HAM-A and PHQ-9. Groups were compared using Kruskal-Wallis and Fisher exact tests, with effect estimates from Firth penalised logistic regression.
Results: Thirty-two patients were analysed (comorbid, n=11; depression only, n=16; anxiety only, n=5). Clinically relevant IBS symptomatology (IBS-SSS ≥75) was present in 8/11 (72.7%, 95% CI 43.5–91.7) of the comorbid group, 1/16 (6.2%, 0.7–25.7) with depression alone, and 0/5 (0.0%, 0.0–37.9) with anxiety alone (p<0.001). Severe GSRS scores (≥40) occurred only in the comorbid group (6/11, 54.5%; p=0.003). Comorbidity remained associated with IBS symptomatology after adjustment for age and sex (OR 27.36, 95% CI 3.09–241.93; p=0.003). HAM-A and PHQ-9 distributions did not differ across groups (p=0.906; p=0.577).
Conclusion: In this small single-centre sample, comorbid anxiety and depression was associated with greater GI symptom burden than either alone, unexplained by psychiatric symptom severity.
Recommendation: Brief GI symptom screening should be considered for psychiatric outpatients with comorbid anxiety and depression, and the association should be confirmed in larger, multicentre, longitudinal studies.
