A Perspective on the Interaction Between Recurrent Lower Urinary Tract Infections and Irritable Bowel Syndrome

Given the potential overlap in risk factors associated with both irritable bowel syndrome (IBS) and lower urinary tract infections (LUTIs), we aimed to identify factors that may contribute to the development of both conditions, as well as recurrent lower urinary tract infections (RLUTIs). Our research also sought to explore overlapping symptoms and interactions between these two disorders.

The study included young women with a history of urinary tract infections. Participants were divided into three groups: women with sporadic LUTIs (NRLUTIs), women with recurrent LUTIs (RLUTIs), and women with both a history of urinary infections (NRLUTI or RLUTI) and a diagnosis of IBS. The diagnosis of IBS is primarily clinical, relying on symptoms and the exclusion of other gastrointestinal disorders. Data from intestinal microbiota tests were combined with information on patients' symptom perception, dietary habits, lifestyle, and knowledge regarding their conditions.

Abdominal pain, constipation, insufficient knowledge about antibiotic and probiotic use, and nutritionally unbalanced diets were identified as common factors associated with both LUTI-IBS and RLUTI.

Our research identified shared risk factors between LUTI, IBS, and RLUTI, suggesting a pathological interdependence between these conditions. Notably, women with RLUTIs often experience gastrointestinal symptoms such as abdominal pain and constipation after consuming foods known to trigger IBS. This highlights that gut dysbiosis is both a risk factor and a potential consequence of RLUTI. The presence of either condition appears to exacerbate the symptoms of the other, further underscoring the intricate connection between RLUTI and IBS in affected individuals.
