# Recurrent urinary tract infections and psychological burden: mechanisms and integrative perspectives

## TL;DR

This paper explores how recurring urinary tract infections and psychological stress influence each other through biological and traditional Chinese medicine perspectives.

## Contribution

The paper proposes four mechanisms linking rUTIs and psychological burden and integrates biomedical and TCM insights for a holistic understanding.

## Key findings

- Four mechanisms—immune dysregulation, endocrine imbalance, microbiome alteration, and neuroendocrine dysfunction—link rUTIs and psychological distress.
- Integrative interventions like CBT, MBSR, and TCM may help manage both rUTIs and psychological symptoms.
- Psychological stress and rUTIs may form a self-perpetuating cycle, requiring combined treatment approaches.

## Abstract

Recurrent urinary tract infections (rUTIs) remain a global health concern with significant physical and psychological impacts, particularly in women. Recent evidence indicates a strong bidirectional association between rUTIs and psychological burden, yet the underlying mechanisms remain incompletely understood.This review integrates findings from biomedical and traditional Chinese medicine (TCM) perspectives to elucidate potential pathways linking rUTIs with anxiety and depression. Four major mechanisms—immune dysregulation, endocrine imbalance, microbiome alteration, and neuroendocrine dysfunction—are proposed to explain this complex interaction. In addition, TCM conceptualizes this relationship through the theory of the “coexistence of disease and depression syndromes” emphasizing that emotional regulation is a key determinant of both urinary and systemic health. By synthesizing these insights, this narrative review underscores the importance of integrative approaches in preventing and managing rUTIs while addressing concurrent psychological distress.

Graphical abstract illustrating the proposed bidirectional relationship between psychological burden and recurrent urinary tract infections (rUTIs). Psychological stress is suggested to influence rUTIs through four interrelated biological pathways: immune dysregulation, endocrine imbalance, microbiome alteration, and neuroendocrine dysfunction. Recurrence of UTIs may further reinforce psychological distress, forming a potentially self-perpetuating cycle. Integrative interventions—including cognitive–behavioral therapy (CBT), mindfulness-based stress reduction (MBSR), and selected traditional Chinese medicine (TCM) modalities—may help alleviate both psychological and urinary symptoms by targeting overlapping physiological and psychosocial factors. These relationships represent associations rather than confirmed causal pathways.
