Episode notes
Lactobacilli Dominate Healthy Vaginas
- The healthy vaginal microbiome is dominated by lactobacilli bacteria that produce lactic acid.
- These bacteria lower pH and produce compounds like hydrogen peroxide that protect against harmful microbes.
Hormones Shape Microbiome Dynamics
- Vaginal microbiome composition changes with age, hormones, and cycles.
- Estrogen levels promote lactobacilli dominance; changes lead to greater microbial diversity.
Gut and Vaginal Microbiomes Connected
- Gut microbiome health affects vaginal microbiome composition.
- Eating fermented foods, vegetables, and fibers benefits both gut and vaginal microbial communities.
