In this episode of the Biohackher Podcast, Azra sits down with Dr Craig Haifer, clinical gastroenterologist, microbiome researcher and one of Australia’s leading voices bridging medicine and preventative wellness, to unpack why gut health is the master regulator of ageing, hormones, immunity and inflammation.
From bloating and brain fog to menopause, mood and longevity, this conversation goes far beyond “eat more fibre” — diving into the real science of the gut–brain–hormone axis and what women need to know to age well.

-
Why bloating isn’t always about food — and how pelvic floor dysfunction and “gut flow” play a major role
-
The surprising reason many gut issues begin in adolescence, not adulthood
-
Why restrictive diets (including long-term low-FODMAP) can backfire — and how to think about diet like a prescription
-
How stress, sleep and the nervous system shape your microbiome more than most supplements
-
What centenarians’ guts reveal about healthy ageing and longevity microbes
-
The truth about probiotics vs prebiotics — and why feeding your own gut ecosystem matters more than chasing trendy strains
