Request for an indicator for associated bowel movement in the bladder diary
Here is the evidence to back my request here:
Top 5 research papers on the interaction between bowel movement and bladder activity occurring in the same timeframe as the bladder activity.
Why this matters :
Bladder diaries often show variable urgency, frequency, and leakage that users can’t explain. A common missing context is **bowel activity and rectal loading** (e.g., constipation, rectal distension, bowel movement timing), which can acutely modulate bladder reflexes and sensations. Without bowel context, apps may misattribute patterns to fluids, caffeine, anxiety, or “random variability.”
What the science shows in plain terms is:
The bladder and bowel share:
- Anatomic proximity - (rectum can mechanically affect bladder/urethra when distended)
- Shared neural pathways (cross-sensitization and reflex cross-talk via pelvic afferents and spinal circuits)
- Shared inflammatory/sensory signalling (bowel inflammation can increase bladder excitability)
Result: bowel state and bowel events can shift bladder capacity, urgency thresholds, detrusor activity, and perceived bladder sensation on the same day—and sometimes within a short timeframe.
Key evidence (5 anchor papers)
- Burgers et al., Journal of Urology (2010), doi:10.1016/j.juro.2010.03.120
Acute rectal distension in children measurably alters lower urinary tract function on urodynamics → direct evidence of time-linked bowel→bladder effects.
- Wyndaele et al., Journal of Urology (2013), doi:10.1016/j.juro.2013.03.045
Colorectal distension modulates bladder inhibition (animal model) → physiologic basis for bowel fullness influencing urgency/frequency.
- Minagawa et al., Journal of Urology (2013)
Colorectal distension changes bladder afferent nerve activity → explains altered bladder sensation/urgency around bowel changes.
- Liang et al., Journal of Neuroinflammation (2012)
Colonic inflammation drives changes in bladder activity via sensory pathway signaling → supports tracking bowel flares alongside urinary flares.
- Scientific Reports (2022)
**Functional constipation** induces bladder overactivity with relevant molecular pathway changes → supports bowel-state markers to interpret urinary frequency/urgency trends.
I trust this is sufficient evidence for adding a “bowel movement associated” indicator to the bladder diary to capture association between bowel movements and urinary events.
Confusing messaging.
Response from developer
Hello and thank you for your feedback. In the App Store description it does say the app is "aimed at men who are seeing a specialist physiotherapist for problems connected to their. . .". However, we will look to make this message clearer earlier on, and state that it is for men who are experiencing symptoms and for men before and after a prostatectomy. Best wishes, Squeezy team.
Not Worth it.
Response from developer
Thank you for taking the time to share your feedback. We’ve intentionally kept the app simple so users can focus on their exercises without unnecessary distractions. The app is a one-off purchase of £2.99, which provides lifetime access to exercise tracking, creating your own plan, reminders, and evidence-based, up-to-date information which is written and curated by clinicians. While information found on the internet or through AI tools can seem convenient, it is often not clinically validated and may be inaccurate or unsafe. Our content is designed to ensure users receive reliable guidance they can trust. Best wishes, Squeezy team.
