Dr. Betsy Greenleaf discusses the gut-brain-vagina connection and how it impacts women's health. She explains that gut health is crucial for overall well-being and can affect mental health, hormone balance, weight, and even libido. The gut-brain-vagina connection is mediated through the microbiome, and imbalances in the gut can lead to various health issues. Dr. Greenleaf emphasizes the importance of a healthy diet, including fermented foods and fiber, in supporting gut health. She also advises against using harsh soaps and detergents on the vaginal area, as they can disrupt the microbiome and cause irritation.
