For IBS-C (constipation-predominant)
Find the rhythm that finally keeps you regular.
IBS-C is the opposite challenge: bloating, hard stools, and going every 3-5 days. A Gut Day connects fibre intake, hydration, movement and stress to actual stool patterns - so you can build a routine that works.
Why generic 'eat more fibre' advice isn't enough
Fibre helps - but the type matters. Soluble fibre (oats, psyllium, kiwifruit) softens stools. Insoluble fibre (bran, raw veg) can paradoxically worsen IBS-C bloating. Add fluids, magnesium intake, walking minutes and stress, and you have 5+ variables to juggle. A Gut Day tracks them all and shows which combination produces a Bristol 3-4 stool for YOU.
What you'll learn after two weeks
Your fibre sweet spot
The grams-per-day range where you go regularly without bloating.
Your trigger combinations
Sometimes it's not one food - it's 'low fluid + sedentary day + stress'.
Your best routine
Morning walk + warm water? Kiwifruit at breakfast? The data tells you.
How A Gut Day helps
Built for this exact problem
Fluid intake quick-log
Tap a glass icon. Water, tea, coffee all count - with caffeine flagged.
- Quick-add glasses
- Cumulative ml total
- Caffeine separation
Movement integration
Steps and walking minutes (Apple Health / Google Fit) cross-correlated with stool patterns.
- Apple Health sync
- Google Fit sync
- Manual movement log
Bristol 1-2 alerts
Hard stools logged trigger a backwards check: was the day before low-fluid? Low-fibre? Sedentary?
How it works for IBS-C
- 1
Log meals + fluids + movement daily
First two weeks are pure baseline.
- 2
Log every stool with Bristol score
Even the misses (no stool today). Frequency is half the data.
- 3
Read the weekly insight
Sundays you get a one-page summary: what worked, what didn't.
- 4
Adjust ONE thing per week
Add a kiwi at breakfast. Or a 20-min morning walk. Re-measure.
The kiwifruit, magnesium and psyllium evidence
Three things have decent IBS-C evidence: 2 green kiwifruit per day (improves stool frequency in trials), magnesium oxide 300-500mg (osmotic laxative effect), and psyllium husk 5-10g (soluble fibre that holds water).
None of these work for everyone. A Gut Day lets you test each as a 2-week trial, then compare your weekly Bristol average before vs after - so you know if it's actually working for YOUR body, not just the average study participant.
Why the morning matters most
The gastrocolic reflex - the urge to go after eating - is strongest in the morning. Most regular people use it without thinking. IBS-C often suppresses it from years of 'no time' or 'not now'.
A simple intervention with strong support in the data: warm fluid + breakfast + a 10-minute window of NOT being on the phone, every morning. The app tracks adherence and stool frequency in parallel.
Frequently asked questions
- Will A Gut Day suggest laxatives?
- No. The app surfaces patterns. Decisions about laxatives, supplements or medication belong with your doctor or dietitian.
- Does it work for chronic constipation that isn't IBS?
- Yes - the same fibre/fluid/movement tracking applies. The IBS-specific insights (stress correlation, FODMAP tagging) are also helpful but optional.
- I don't go every day. Is that abnormal?
- Not necessarily. 'Normal' is anywhere from 3 times per day to 3 times per week, as long as it's not painful and stools are Bristol 3-4. The app tracks your normal.
- Can I track magnesium or psyllium intake?
- Yes - log them as supplements with dose. Insights treat them as variables alongside food.
- What if my fibre is already high but I'm still constipated?
- Often the issue is fluid (under 1.5L/day with high fibre makes things worse) or insoluble:soluble ratio. The app shows the breakdown so you can rebalance.
