New research on menopause and the gut, published this month. 🚨
A longitudinal study followed 964 women across the menopause transition and found increases in markers of gut barrier damage and immune activation linked to microbial translocation. Those markers rose during the transition itself, not in the years before or after it.
What I find validating is that this builds on research I referenced while writing The Menopause Gut (link in bio). In 2020, the same research group published the first human study examining the association between menopause and gut barrier outcomes within SWAN, a large multiethnic U.S. cohort focused on women’s health through the menopause transition.
Now we have a much larger longitudinal dataset pointing in the same direction.
As hormones decline, we are seeing more evidence of compromised gut barrier integrity, microbial translocation, and changes in immune activation.
Clinically, this is part of why we may see more autoimmunity, more food sensitivities, and changes in how the immune system responds to opportunistic bacteria, viruses, and fungi in midlife.
The mechanisms and long-term consequences still need more research. But the connection between hormonal decline, the gut, and immune regulation continues to hold up.
