Your Gut, Your Brain, and Your Sleep Are All Aging Together
September 3, 2026·9:56·Episode 116
Quick Summary
This episode covers three new findings: gut bacteria start shifting during perimenopause — possibly years before your last period; a new study looks at estriol (a lesser-known estrogen) and its effect on brain fog; and a PubMed study published this week suggests chronic sleep deprivation may actually accelerate ovarian aging through a specific inflammatory process, not just result from it.
Your Gut, Your Brain, and Your Sleep Are All Aging Together

Key Takeaways
- ✦The gut microbiome appears to start changing during perimenopause, before periods stop — meaning gut symptoms in your 40s may be hormonally driven, not random.
- ✦A new study found that estriol, a form of estrogen less commonly used in hormone therapy, showed improvements in brain fog — but the study is small and not yet enough to change clinical practice.
- ✦Chronic sleep deprivation may trigger ovarian aging through an inflammatory pathway involving something called IL-17 signaling — suggesting sleep loss isn't only a symptom of hormonal change, it may contribute to it.
- ✦Most hormone therapy research focuses on estradiol; estriol is worth watching but needs larger trials before drawing firm conclusions.
- ✦The gut-hormone connection is an emerging area of research — interesting and plausible, but still early enough that anyone selling you a "menopause gut protocol" supplement is running ahead of the science.
