Two, caffeine enhances the sensation and contractility of the bladder. Another way caffeine can affect prostate health is through its ability to irritate the bladder because it is a theoxanthine, a family of drugs that includes theobromine (found in chocolate) and theophylline (found in tea). Theophylline also stimulates and irritates the bladder.
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: The voiding and mental health symptoms will be greatest in the high dose treatment and lowest in the placebo treatment.
