In this episode, we’re diving deep into the gut-stress connection and how chronic stress impacts digestion, immunity, and overall gut health. We’ll unpack how the HPA axis (your body's stress response system) directly affects gut motility, stomach acid production, and microbial balance - leading to issues like bloating, food sensitivities, Candida overgrowth, and even leaky gut. Plus, we’ll explore why low secretory IgA (SIgA) is connected to adrenal health and levels weaken gut immunity and make you more susceptible to infections. Tune in as we share practical strategies to break the stress-gut cycle, support adrenal health, and restore balance from the inside out!
