Estrogen-Gut Microbiome Axis - Is It Impacting You?
Updated: Mar 20
Struggling with sore breasts, endometriosis, polycystic ovary syndrome, fertility and PMS symptoms?
I here to share with you some exciting emerging research indicating that your gut health plays a role in your hormonal health, especially estrogen.
We clear estrogen through a phase 2 liver detox process whereby the liver (via the bile) pushes the hormone into the gut. Think of the estrogen like a present wrapped with a pretty bow on it – it is ready to be excreted by the body through the stool (your poop!). However, if you have high β-glucuronidase, this enzyme in the gut acts like a cheeky child undoing all the bows on all of these presents (i.e. reducing the deconjugated estrogen)(1, 2). The result – the estrogen is recirculated through the body (which is not good), often resulting in the symptoms I shared above due to the build-up in the body.
The good news is that you can learn what your level of β-glucuronidase through a gut microbiome test (this poop test also provides you a wealth of information about what’s going on in there – if you have leaky gut, dysbiosis, good microbial diversity etc) and address it through nutritional therapy.
