I was able to attend the AANP Health Policy conference in Washington DC this week. I am always happy to be back in DC, but 12 degrees was a bit 🥶 It was great to catch up with friends and make some new ones at the conference. On Tuesday, it was a bit warmer and we went to Capitol Hill to lobby for improved health policies including classifying nurses and NP as PROFESSIONALS! I can't believe that is an issue we need to address, but here we are. Advocacy is something all of us can do more of to improve the circumstances we as RNs and NPd work in while also working to improve healthcare for everyone. If not us, then who?

It’s not an alternative trend. It’s a return to what healthcare should be.

Functional nursing is how we stop managing disease and start promoting true healing. This isn’t extra. It’s essential.

Functional psychiatry is one of the least common niches in the functional medicine world, but it is often where patients experience some of the most profound “whole person” care. In this episode, Brigitte Sager interviews Everest Goldstein, board-certified psychiatric nurse practitioner and IFM certified clinician, about what functional psychiatry really means, how she built her practice, and why nursing is uniquely positioned to lead in this space.

Everest shares her own turning point after Lyme disease, when a provider spent the time to take a full functional history and connect the dots. From there, she explains how functional psychiatry treats depression and anxiety as symptoms with root causes, not labels that end the conversation. You’ll hear practical, surprising examples of how gut health, cortisol dysregulation, dysbiosis, H. pylori, constipation, and yeast overgrowth can drive mood symptoms, and why foundations like sleep, stress, movement, and nutrition matter more than “shiny objects” like endless supplements, peptides, or IVs.

They also discuss building community as a clinician, the realities of starting a practice, and how nurses can confidently work within scope by focusing on foundational health behaviors and patient education.

Key Takeaways:
➡️ Functional psychiatry is a root-cause approach that integrates conventional and functional tools to restore whole-person health
➡️ Depression and anxiety can reflect underlying physiology such as gut dysfunction, cortisol patterns, hormones, sleep disruption, or unresolved trauma
➡️ Gut health is a recurring driver in mental health cases, including dysbiosis, H. pylori, constipation, and yeast overgrowth
➡️ “Treatment-resistant depression” often signals an incomplete root-cause workup, not a lack of options
➡️ Many medication side effects and poor responses make more sense when you evaluate stress physiology (including low cortisol patterns)
➡️ Nurses can create major impact within scope by prioritizing foundations: nutrition, sleep, movement, stress regulation, and lifestyle change support
➡️ New functional providers often overuse supplements; experienced clinicians typically simplify and return to the basics
➡️ Sustainable practice building requires boundaries, community, and a clear niche that patients can understand

It’s not radical to care about root causes. It’s responsible.

The science supports it. The outcomes demand it.
Functional nursing honors the full complexity of what healing really takes.

Elimination diets sound simple on paper, but in real life, they can create confusion, overwhelm, and unexpected setbacks for both nurses and their patients. In this episode of The Functional Nurse Podcast, Brigitte Sager breaks down the top 7 challenges functional medicine nurses face when guiding clients through an elimination diet, and how to set the stage for success from the start.

You’ll learn how to help patients navigate challenges and avoid common reintroduction mistakes that sabotage their hard work. Topics include:
➡️ How to choose the right timing and “create space” before starting
➡️ Simplifying to reduce overwhelm and prevent burnout
➡️ What to do when patients feel worse before they feel better
➡️ How to handle slip-ups
➡️ Making the reintroduction phase a true experiment with structure and tracking
➡️ Avoiding common mistakes like reintroducing foods during illness or flare-ups
➡️ Why food sensitivities are not the root cause

This episode empowers nurses to guide patients with confidence, empathy, and clarity while also keeping the focus on gut repair, root cause healing, and sustainable behavior change.
