The Gut Microbiome in Eating Disorders

Ahh, the microbiome — the great unknown.

As more and more evidence emerges on the gut microbiome in eating disorders, it's increasingly clear that there's a *lot* happening in the gut. Which makes sense, really: the gut microbiome is heavily influenced by diet quality, adequacy and diversity, not to mention the well-known impact of mental health.

When it comes to an eating disorder, your gut is going through it too. There are many changes and flow-on effects happening beneath the surface that we simply can't see — and don't yet fully understand. From what we know so far, the gut microbiome and gut function don't necessarily "bounce right back" in early ED recovery, so understanding what we *can* do to support it over the long term is genuinely helpful.

What we know supports the gut microbiome long-term

- Eating a nutritionally adequate and diverse diet

- Limiting antibiotic use to medical necessity

- Supporting the nervous system and mental wellbeing

- Getting sufficient, quality sleep

- Building a positive relationship with movement

None of this is a quick fix, and it's not about perfection either. It's simply a reminder that recovery isn't just a mental process — it's a whole-body one, and the gut is very much part of that picture.
