Episode Summary
“What if your bloating, fatigue, brain fog, anxiety, stubborn weight gain, and hormone symptoms are actually starting in your gut?”
In this episode, Dr. Mariza sits down with Dr. Cassie Smith — dual board-certified endocrinologist, founder of Modern Endocrine, and author of Fix Your Gut, Fix Your Hormones — to unpack the powerful connection between gut health, hormone balance, stress, metabolism, inflammation, and reproductive health.
Together, they dive into how chronic stress, poor gut health, blood sugar dysregulation, inflammation, and lifestyle overload silently impact everything from cortisol and insulin to estrogen, progesterone, thyroid function, and fertility.
Dr. Cassie explains why so many women are told their labs are “normal” while still feeling exhausted, bloated, anxious, inflamed, and disconnected from their bodies — and why gut dysfunction is often the missing piece conventional medicine overlooks.
They also explore the growing metabolic and hormonal crisis happening in younger women, the connection between PCOS, insulin resistance, gut dysfunction, and birth control, and why many women are struggling to restore healthy cycles and fertility later in life.
This conversation is a powerful reminder that hormones do not work in isolation. Your gut, nervous system, metabolism, sleep, stress resilience, and hormones are all deeply interconnected.
If you’ve been feeling like your body is trying to tell you something but nobody has connected the dots yet, this episode will help you understand where healing truly begins.
