Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to observe effects of caffeine on overactive bladder symptoms and wellbeing. This study looks at whether caffeine has bad effects on urinary symptoms or if lower doses of caffeine decrease the effects. The study will propose the following hypothesis: 1. The voiding and mental health symptoms will be greatest in the high dose treatment and lowest in the placebo treatment. 2. The low dose treatment will produce more voiding and mental health symptoms than the placebo treatment. 3. Voiding and mental health symptoms will be mediated by hydration status of the patient which will be assessed using a Tanita Scale.
