How I Work
— And Why
A guide to understanding functional medicine and what to expect when we work together.
Kim Pellegri, ACFMHC, MRHP, AFNTP
If you’ve never worked with a functional medicine practitioner before, I want to start by telling you something important: this is not going to feel like a typical doctor’s appointment. And that’s the point.
What you’re about to experience is a completely different way of thinking about your health — one that asks why your body is struggling, not just what to name the symptom and which drug to assign to it. This guide is my way of walking you through how I think, how I work, and why the process looks the way it does. I want you to feel informed, confident, and like a true partner in your own care.
1. Your Body Is a Web, Not a List of Separate Problems
One of the first things I want you to understand is that the human body doesn’t work in isolated compartments. Everything is connected. Your gut talks to your brain. Your blood sugar affects your hormones. Your stress response drives inflammation. Your sleep quality impacts your immune system. And on and on.
This interconnected map of how your systems affect one another is what we call the physiological web. It means that what looks like five separate problems on the surface is often one root-cause pattern expressing itself in multiple places at once.
Most people who come to me have already been through the conventional system. They’ve seen multiple specialists, received multiple diagnoses, and are taking multiple medications — one for each “problem.” But nobody ever asked what was pulling on all of those systems at the same time.
That’s the question I’m here to answer.
2. Peeling the Layers: The Onion Approach to Chronic Illness
Here’s the most important metaphor I use when I explain functional medicine to someone who’s brand new to it: your health is like an onion.
When you’ve been struggling with chronic symptoms for months or years, there are typically many layers of dysfunction stacked on top of one another. What you’re feeling on the surface — the fatigue, the brain fog, the bloating, the anxiety, the pain — is not the whole story. It’s the outermost layer of a much deeper picture.
My job is to peel those layers back, one at a time, in the right order.
Why in order? Because layers don’t all have equal weight. Some layers are sitting on top of everything else and making the whole system unstable. Until we address those, we can’t clearly see — or effectively treat — what’s beneath them.
A Real Example
Imagine someone comes to me with 30 symptoms: fatigue, anxiety, digestive issues, joint pain, hormonal imbalances, brain fog, and more. We start with the most foundational layer — maybe blood sugar instability and disrupted sleep — and address just those two things first.
Two months later, 15 of those 30 symptoms are gone. Not because we treated all 30, but because we removed the smoke screen that was making everything worse. Now I can see the actual fire underneath.
This is the work. It’s not always fast. It’s not always linear. But it’s the most efficient path to real, lasting change — because we’re not chasing symptoms. We’re changing the terrain.
3. We Work in Phases — And Here’s Why That Matters
I don’t walk into your case with a fixed, one-size-fits-all protocol. I walk in with a strategy — and that strategy evolves as you do.
I organize every client’s care into phases. Think of each phase as a chapter in your health story. Each one has a specific goal, and we track how you respond before we move to the next. Here’s what that might look like in practice:
- Phase 1: Stabilize the foundation — blood sugar, sleep, energy, gut motility
- Phase 2: Run targeted labs to go deeper — autoimmunity, inflammation, hormones, gut microbiome, toxins
- Phase 3: Address what the labs reveal and reduce systemic burden so your body can tolerate deeper interventions
- Phase 4+: Refine, optimize, rebuild — this is where we move into true root-cause resolution and long-term resilience
This phased approach is not a sign that things aren’t working. It’s the sign that we’re doing this right. Chronic conditions didn’t develop overnight, and they don’t resolve overnight either. But every phase brings you closer to the version of yourself you’re working toward.
4. Everything You Do Is Both Therapeutic AND Diagnostic
This is one of my favorite things to explain to clients, because it completely reframes what “responding to treatment” means.
When I give you a recommendation — a dietary change, a supplement, a lifestyle shift — I’m watching how your body responds with just as much interest as I’m hoping for improvement. Your response is information.
If we work on improving your sleep and you suddenly feel 50% better across the board — that tells me sleep dysregulation was a major driver in your case.
If we improve your sleep and your anxiety is still through the roof — that tells me something else is maintaining it, and now we go find that.
Either way, we learn. Either way, we move forward.
Nothing we do together is wasted. Every intervention either helps you heal or helps me understand your physiology more deeply. That’s the beauty of this process.
5. This Is a Partnership, Not a Prescription
I will be direct with you: the way I work requires your active participation. I’m not handing you a protocol and sending you on your way. I’m walking through this with you.
That means:
- You show up to follow-ups ready to track and report how you’re feeling — not just “good” or “bad,” but specifically.
- You give the dietary and lifestyle changes a real chance, because they are not optional additions to the plan — they are the foundation.
- You communicate with me when something isn’t working, because that’s data, not failure.
- You trust the process, even when it feels slower than you’d like, because sustainable healing is not a shortcut.
In return, I will always have a plan. I will always be thinking about your case between sessions. I will never walk into a follow-up without knowing where we are and where we’re headed. You will always know what phase we’re in, what the goal is, and why.
6. What You Can Expect in Our Work Together
At the Start
We do a thorough intake — symptoms, history, diet, lifestyle, past labs, everything. I’m building a picture of you, not just your diagnosis.
Testing
I use functional blood chemistry, specialty labs (gut, hormones, toxins, immunology, genetics), and sometimes imaging referrals to get a complete picture. I read labs through a functional lens — looking at optimal ranges, patterns, and trends, not just “normal vs. abnormal.”
Personalized Protocols
Every recommendation I make is individualized. Your food plan, supplement protocol, and lifestyle targets are built around your labs, your genetics, your history, and your life. There is no generic plan here.
Ongoing Follow-Up
We meet regularly to review your progress, adjust the plan, and move through phases together. I document everything, track your trajectory over time, and always bring a clear clinical eye to our sessions.
7. A Note on Timelines
I will not promise you a timeline, because I don’t know how many layers your onion has until we start peeling. What I can promise you is this:
- I will work through your case with intention and strategy.
- I will never keep you on a path that isn’t working.
- I will always be honest with you about where we are and what I see.
- And I will never stop asking why.
For some people, major shifts happen in the first few months. For others with deeply complex or long-standing conditions, we may be 8–9 months in and still refining Phase 1 — and that is not failure. That is the reality of hidden viruses, chronic infections, environmental, toxicities, auto immune disease, or chronic disease,etc. and it means we’re doing the deep work, not the surface work.
I’m Glad You’re Here
Choosing to pursue functional medicine is a courageous decision. It means you’re done settling for feeling less than your best, and you’re ready to do the actual work of understanding your body at a deeper level.
I’ve been practicing functional medicine since 2014 and studying herbal and whole-body medicine since the late 1990s. I have trained with some of the most rigorous programs in the field, and I bring everything I know to every single client case. You are not a diagnosis to me. You are a whole, complex human being, and that is how I will always treat you.
Let’s peel the layers back — together.
