Pain, Fatigue, and Bloating Aren’t Random, They’re Messages w/ Dawn Giammalvo
How can you feel relatively ok and brush off your nagging symptoms as “normal”? What you don’t realize is that they are not normal, just common. The signals are our body’s only way of communicating, but we have either forgotten or not been taught how to listen.
Key Takeaways:
- Any symptom, no matter how common, is never normal.
- Systemic inflammation is at the root cause of most of our symptoms and diseases.
- There isn’t a single pharmaceutical drug out there that can fix it - only lifestyle changes.

Understanding the Gut-Hormone-Brain Triad and What It Means For Your Health w/ Alissa Hodgson
When it comes to lasting health, it’s never just one thing. Your gut, hormones, and brain are in constant communication—and the health of one system directly impacts the others.
This “triad” is anchored by the liver and influences nearly every area of your well-being. If you only address one system in isolation, you may see short-term relief, but eventually metabolic chaos catches up.
In this episode of the Health Detective Podcast with Alissa Hodgson, we dive into the gut–hormone–brain connection—what it means, why it matters, and how a comprehensive approach creates better outcomes for everyone, from busy women navigating hormone changes to families supporting loved ones with Down syndrome.

Anxiety, Fatigue, and Mood Issues ARE NOT Normal In Motherhood! w/ Nichole Krueger
Feeling exhausted, anxious, or like you’ve lost yourself in motherhood?
You’re not alone—and it’s not “just stress” or “part of being a mom.” Burnout, anxiety, and constant fatigue are often signs of deeper, correctable imbalances.
Through functional lab testing, we uncover the hidden root causes—like gut issues, hormone imbalances, nutrient deficiencies, or other stressors—that conventional approaches often miss. When you finally see the data, you realize you’re not crazy, you’re not failing, and it’s not all in your head. You just need the right roadmap.
That’s where the D.R.E.S.S. approach (diet, rest, exercise, stress reduction, supplementation) comes in. With small, sustainable changes that fit your busy life, you can restore your energy, balance your mood, and feel calm and confident again—without overhauling everything at once.
