About this trial
The goal of this clinical trial is to learn if probiotics can help improve symptoms in adults with overactive bladder (OAB) and anxiety. The main questions it aims to answer are:
1. Does taking probiotics lower the number of times participants need to urinate in a 24-hour period? 2. Does taking probiotics lower participants' anxiety levels?
Researchers will compare probiotics to a placebo (a look-alike powder that contains no active bacteria) to see if the probiotics work better to treat OAB and anxiety when both groups also use standard behavioral therapy (like bladder training).
Participants will:
1. Take probiotics or a placebo twice a day for 12 weeks. 2. Learn and practice bladder training using a manual and educational videos. 3. Keep a 3-day diary of when they urinate and what they drink at the beginning, middle, and end of the study. 4. Answer survey questions about their anxiety and quality of life during clinic visits. 5. Provide urine samples for routine checkups to ensure they do not have infections.
