In response to last week's newsletter all about 💩, I got a message from a friend sharing that her digestion has absolutely tanked in the last few years, and she's worried about what it means.
One thing I didn't elaborate on that newsletter is that declining hormones often throw off our gut health. If you've noticed some changes after 40, it's possible that lower Estrogen levels are playing a role. It doesn't mean there is something catastrophic going on, but rather a cascading decline of a healthy microbiome that has downstream effects you may be noticing.
More bad news about midlife?
We might not have been aware of how hormones play a role in declining gut health. And while it's hard to hear all the ways we're falling apart (one more thing to deal with?) take this info as more evidence that working on our microbiome is a worthwhile endeavor.
Estrogen and gut bacteria have a two-way relationship: hormones help shape the gut environment, and gut bacteria help process estrogen. As estrogen declines it can change your microbiome.
Here are a few ways this may show up:
* Bacteria balance: Changes in estrogen can influence the types and balance of bacteria living in your gut, lowering beneficial bacteria which makes room for detrimental levels to rise.
* Gut lining: Estrogen plays a role in supporting the intestinal barrier and immune function. Lower levels = thinner lining.
* Digestion: Bloating, constipation or changes in bowel habits are common during perimenopause.
* Estrogen recycling: Gut bacteria help determine how much estrogen gets recycled versus eliminated. Estrogen detox can slow in midlife, which plays a part in higher breast cancer levels after 40.
