If you’ve followed me for any length of time, you’ve heard me use the words functional medicine more times than I can count. I talk about gut health, hormones, metabolic health, inflammation, stress, nutrient status, environmental exposures, and how all of these things connect.
But recently, I realized I may have skipped over a pretty important question.
What exactly is functional medicine, anyway? And maybe more importantly, how is it actually different from the medicine you’re already receiving?
After more than 25 years practicing conventional medicine, I think I’m in a unique position to answer that. I didn’t leave conventional medicine because I stopped believing in it. I still prescribe medications when they’re appropriate. I order traditional labs. I refer to specialists. And if you have an acute medical problem or a disease that needs treatment, I absolutely want you receiving the conventional medical care you need.
What changed for me was realizing that there was another group of patients we weren’t serving particularly well. They weren’t necessarily sick by traditional definitions, but they certainly didn’t feel well. And telling them everything looked “normal” wasn’t answering the question they came in asking.
The Question That Changed How I Practice Medicine
Traditional medicine is largely designed to answer an incredibly important question: What disease or diagnosis could explain these symptoms?
Functional medicine doesn’t abandon that question. It adds another one.
What factors may be contributing to why this person feels this way, and which of those factors can we change?
That may sound like a small distinction, but it completely changes the conversation.
If you come to me exhausted, bloated, gaining weight, sleeping poorly, struggling with brain fog, and feeling like your hormones have taken on a life of their own, I’m not interested only in assigning each symptom to its own category. I want to step back and look at the person experiencing all of them.
How are you sleeping? What are you eating, and are you getting enough of what your body actually needs? How is your gut functioning? What is happening with your blood sugar and metabolic health? Are you maintaining muscle? What medications are you taking? Where are you in the hormonal transitions of midlife? What does your stress load look like? Are there environmental exposures that may matter?
Your body doesn’t operate in departments, even though our medical system often has to.
That’s one of the biggest differences functional medicine has brought to the way I practice.
It’s Not Always About Finding One “Root Cause”
The phrase root cause gets used a lot in functional medicine, and I use it too. But social media has turned it into something much simpler than human biology actually is.
There isn’t always one hidden culprit responsible for everything you’re experiencing.
Sometimes what I see is a woman who has spent years accumulating small changes. Sleep deteriorated during perimenopause. Stress increased. Exercise became less consistent because she was exhausted. Muscle started disappearing. Blood sugar became harder to regulate. Her gut became more reactive, so she began eliminating more and more foods. Somewhere along the way she accumulated a cabinet full of supplements, each one intended to fix a different symptom.
Which one is the root cause?
Sometimes that’s the wrong question.
What matters more is understanding how those pieces are interacting and identifying where we have the greatest opportunity to change the trajectory.
That is where functional medicine becomes useful rather than simply interesting.
So What Would I Actually Do Differently?
This is probably what most people really want to know.
Functional medicine doesn’t mean I automatically order every specialty test available, put you on an impossibly restrictive diet, and send you home with 27 supplements. In fact, sometimes the most important things we uncover are surprisingly basic.
Maybe you’re not eating enough protein. Maybe you’re sleeping six hours a night and compensating with caffeine. Maybe you’re having a bowel movement every three days and have simply decided that’s “normal for you.” Maybe you’ve lost significant muscle during midlife while focusing exclusively on the number on the scale. Or maybe you’ve become so overwhelmed by conflicting health advice that you’re trying to do everything and have no idea what is actually helping.
Other times, your history and symptoms tell me we need to look more deeply at your gut, nutrient status, metabolic health, hormones, or another area. And sometimes what I hear tells me that you need further conventional medical evaluation before we do anything else.
The goal isn’t more testing. It isn’t more supplements. And it certainly isn’t more complexity.
The goal is to ask better questions, figure out what matters most, and address things in an order that makes sense.
This Isn’t Conventional Medicine Versus Functional Medicine
This may be the misconception I most want to change.
I practiced conventional medicine for decades, and I know what it does extraordinarily well. I would never want to practice without it.
If you have pneumonia, I don’t want to “heal your terrain” instead of treating your pneumonia. If you need thyroid medication, hormone therapy, blood pressure treatment, an antibiotic, or another prescription, there are times when medication is absolutely the right tool.
But I also don’t think writing the prescription always has to be the end of the conversation.
Can we also ask what contributed to the problem? Are there things we can change that may improve how you feel now and reduce risk later? Can we build health while we’re treating disease rather than waiting for another diagnosis to appear?
That is the space where I believe conventional and functional medicine work beautifully together.
Maybe We’ve Made Health Too Complicated
The longer I do this work, the more convinced I am that most women don’t need more health information. They’re already drowning in it.
Fast. Don’t fast. Eat carbohydrates. Don’t eat carbohydrates. Track your glucose. Fix your cortisol. Heal your gut. Balance your hormones. Take this supplement. Avoid that food.
No wonder women are confused.
You shouldn’t need a medical degree-or spend three hours a day listening to health podcasts-to figure out how to take care of yourself. What you need is a way to determine which information actually applies to you, what deserves your attention first, and what you can stop worrying about.
That, more than anything, is what functional medicine means to me today.
It isn’t about abandoning good medicine or chasing every possible abnormality. It’s about stepping back far enough to see the whole person, connecting the pieces that actually matter, and creating a plan that makes sense for the person sitting in front of me.
Because ultimately, the goal isn’t to turn you into an expert in functional medicine.
The goal is to help you understand your body, know what to work on, and feel like yourself again.
