Rebuilding Your Gut After Antibiotics
Antibiotics save lives but disrupt the microbiome. Here is an evidence-based plan to recover diversity — and confirm it's returning.
Antibiotics are essential but blunt — they reduce microbial diversity along with the target infection. Recovery is very possible, and now observable.
What antibiotics do to the gut
By clearing bacteria broadly, antibiotics temporarily lower diversity and can cause digestive upset. Most people recover, but the process benefits from support.

The recovery plan
Emphasise diverse fibre and fermented foods, stay hydrated, and consider probiotics with clinical guidance. Reintroduce variety gradually to rebuild diversity.
- Diverse fibre intake
- Fermented foods
- Hydration
- Probiotics with guidance
“Understand recovery after antibiotics — with data instead of guesswork.”
Confirming recovery
Monitoring digestive patterns shows diversity and regularity returning over the following weeks.
