A Gut DayA Gut Day
After antibiotics

Rebuild your gut after a course.

A single antibiotic course can shift your microbiome for 6 to 12 months. A Gut Day guides the recovery with fibre, fermented foods and gentle symptom tracking.

What antibiotics do to your gut

Antibiotics kill the bacteria they target plus many useful gut bacteria as collateral. Diversity drops, beneficial species shrink, and opportunistic species (sometimes including C. difficile) get more room. Most people recover within months, but the trajectory is faster and more complete with deliberate diet support. A Gut Day provides the structure.

Your 12-week recovery framework

Weeks 1 to 2: rebuild gently

Soluble fibre, fermented foods, hydration. Avoid unnecessary restriction.

Weeks 3 to 8: diversity drive

Aim for 30 different plant species per week. The app tracks species count.

Weeks 9 to 12: cement and assess

Continue diversity. Compare baseline symptoms to pre-antibiotic state.

How A Gut Day helps

Built for this exact problem

Plant species counter

Each unique plant food (vegetable, fruit, nut, seed, herb, spice, grain, legume) counts as one species. The target is 30 per week.

  • Auto-counted from meals
  • Weekly diversity score
  • Suggestions to fill gaps

Fermented food tracker

Yoghurt, kefir, kimchi, sauerkraut, kombucha - tracked daily. The target is some fermented food on most days.

  • Fermented food log
  • Weekly streak
  • Brand database

Symptom recovery timeline

Track bloating, urgency, stool consistency over the 12 weeks. See the recovery curve.

  • Pre/post comparison
  • Weekly trend
  • Stalled-recovery alerts

Probiotic support

If you take a probiotic, log strain and dose. The app tracks any symptom correlation.

  • Strain library
  • Dose tracking
  • Effectiveness scoring

How A Gut Day runs your recovery

  1. 1

    Mark your last antibiotic dose

    The app starts a 12-week recovery timeline.

  2. 2

    Follow weekly diet goals

    Each week the app suggests 2 to 3 new plant species and a fermented food to add.

  3. 3

    Track symptoms once daily

    Bloating, stool quality, energy. Three sliders, 30 seconds.

  4. 4

    Review at week 12

    See your diversity, fermented intake and symptom trajectory. Compare to baseline.

Why probiotics alone are not enough

Most commercial probiotics deliver a few strains in capsule form. They can help with specific things (antibiotic-associated diarrhoea, for instance) but they do not rebuild ecosystem diversity. That requires food diversity over weeks.

A Gut Day tracks both - probiotic supplements and dietary diversity - so you can see what is actually moving your symptoms.

When to worry: post-antibiotic complications

Persistent diarrhoea more than a week after the course ends, blood in stool, fever, or severe abdominal pain can indicate C. difficile infection or other complications. The app's red-flag detection prompts you to seek care if symptoms match.

For most people though, recovery is uneventful and just needs structure.

Frequently asked questions

Do I need to take a probiotic?
Not necessarily. Diet diversity matters more. Specific probiotics (like S. boulardii) can help during the antibiotic course itself, but the long-term rebuild is dietary.
How long until I feel normal?
Most people feel normal within 4 to 8 weeks. Microbiome composition can take 6 to 12 months to fully reset.
What if I have to take antibiotics again?
The app tracks repeat courses and shows the cumulative impact. Some patterns of repeat courses (e.g. recurrent UTIs) need a longer-term gut strategy.
Is this for kids too?
Yes - the kid-friendly mode includes the antibiotic recovery framework with age-appropriate diversity goals.
What should I avoid during recovery?
Unnecessary restriction. Strict low-FODMAP or elimination diets right after antibiotics can actually slow microbiome recovery. Diversity wins.
