Abstract

BACKGROUND:

Overactive bladder syndrome (OAB) is defined as a symptom complex comprising urgency, with or without urge incontinence, and usually frequency and nocturia. The association between irritable bowel syndrome (IBS) and bladder symptoms has been reported. This study is designed to investigate whether functional dyspepsia (FD), like IBS, is associated with OAB.

METHODS:

A web surveys containing questions about OAB, FD, IBS, and demographics were completed by 5494 public individuals (2302 men and 3192 women) who have no history of severe illness. The prevalence and overlap of OAB, FD, and IBS were examined.

KEY RESULTS:

Among participants with FD, 20.5% could also be diagnosed with OAB (odds ratio [OR]: 2.85; 95% confidence interval [CI]: 2.21-3.67). Although concomitant FD and IBS were more strongly associated with OAB (OR: 4.34; 95% CI: 2.81-6.73), OAB was also highly prevalent among participants with FD but without IBS (OR: 3.09; 95% CI: 2.29-4.18). Among participants with FD, an overlapping OAB condition was more prevalent in those with both postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS) (OR: 3.75; 95% CI: 2.48-5.67) than in those with PDS or EPS alone. Among participants with OAB, the severity of bladder symptoms was greater in participants with dyspeptic symptoms than without them.

CONCLUSIONS & INFERENCES:

Overactive bladder syndrome is common among FD patients, even if they do not have IBS. To improve FD patients' quality of life, it will be important to provide management for OAB.
