No, it's not a typo.

Your oestrobolome is the collection of gut bacteria specifically responsible for breaking down and eliminating oestrogen from your body. When it's working well, excess oestrogen gets processed and excreted efficiently. When it's not - through antibiotics, a poor diet, or chronic stress- that oestrogen gets reabsorbed back into the bloodstream instead of leaving your body.

The downstream effects: worsening PMS, heavier periods, hormonal acne, bloating, low mood, and over time, increased breast cancer risk.

Most women have never heard of it and yet it sits at the centre of hormonal health.

3 things you can do tomorrow to support it:

1. Add fibre, specifically. Fibre binds to excess oestrogen in the gut and carries it out of the body. Aim for a variety: flaxseeds, lentils, leafy greens, oats. Diversity of plant foods = diversity of gut bacteria.

2. Cut back on alcohol. Alcohol directly impairs the liver's ability to process oestrogen and disrupts gut bacteria balance. Even moderate intake has been shown to elevate circulating oestrogen levels. One less drink is a hormonal act.

3. Eat fermented foods daily. Yoghurt, kefir, sauerkraut, kimchi, miso -  these introduce beneficial bacteria that support a healthy microbiome and, in turn, a functioning oestrobolome. One portion a day is enough to start shifting the balance.

Your gut and your hormones are not separate systems. It's time we stopped treating them that way.
