Do you ever feel like your body is working against you? Maybe you wake up exhausted, no matter how much you sleep, or struggle with brain fog that makes it impossible to focus. You’ve seen doctors, tried medications, and followed all the advice you’ve been given, yet the symptoms persist. It’s frustrating, overwhelming, and can leave you feeling stuck.
But what if the real issue isn’t just the symptoms themselves—but the approach to treating them? This is where Functional Medicine comes in. Unlike conventional medicine, which often focuses on managing symptoms, Functional Medicine digs deeper to uncover the root cause of your health challenges. It’s a personalized, science-backed way to address chronic fatigue, brain fog, and more—helping you finally reclaim your energy, focus, and love for life.
If you’ve ever heard the term ‘Functional Medicine’ or even ‘Holistic Medicine’ but aren’t really sure what they really mean or entail, you’re in the right place. Today, I’m diving into exactly what Functional Medicine is, how it works, and why it’s completely transforming lives for people just like you.
Now, I know these terms can feel a bit abstract. You might have heard them thrown around in conversations about wellness or seen them in articles about alternative health approaches, but it’s not always clear what they actually mean—or more importantly, how they apply to you.
So, let’s dive in.
What is Functional Medicine?
Let’s strip away the mystery and start at the beginning. Functional Medicine isn’t just another health trend—it’s a radically different way of looking at health, illness, and healing, that I believe is the future of medicine. In fact, it’s the approach I’ve built my entire practice around because, quite frankly, it just works.
Functional Medicine is all about asking better questions. Instead of focusing solely on symptoms—like fatigue, memory lapses, or brain fog—it asks, ‘Why are these symptoms happening in the first place?’
At its core, Functional Medicine takes a step back to look at the big picture. It’s patient-centered, meaning it’s designed to treat you as a whole person, not just a collection of specific symptoms or diagnoses.
Conventional Western medicine focuses on diagnosing and treating those isolated symptoms, often using medications to manage them. This works extremely well for more acute situations such as a bacterial infection or heart attack. However, it hasn’t done as well treating chronic conditions like diabetes, high blood pressure, depression, fatigue, or even dementia, which is probably why you’re reading this blog post right now. Functional Medicine, on the other hand, looks at the bigger picture, like I said, identifying patterns and uncovering the root cause of your symptoms to create a personalized plan for you to heal. It’s about understanding why your body is out of balance, not just treating what hurts.
So, let’s think of your body as an orchestra. Every system—your brain, gut, hormones, immune system, metabolism, and even your emotions—needs to work together in harmony to create a beautiful symphony. Functional Medicine is like the conductor, helping those systems get back in sync (or in tune) so you can feel like yourself again.
It also recognizes that no two people are the same. For example, two people with brain fog might have completely different root causes—like nutrient deficiencies for one person and chronic inflammation for the other. Functional Medicine digs deeper to uncover these root causes and create that personalized roadmap for healing I mentioned earlier.
That being said, Functional Medicine does not exclude or reject the medical knowledge we’ve gained from conventional medicine. Instead, it treats it as one tool in the toolbox instead of the only tool in the toolbox.
And, as a side note, I’m not knocking all our incredible conventional medicine providers. I was also originally trained in conventional pharmacy. These providers are really good at what they do. They just weren’t taught how to look at the body this way. And that’s not their fault.
But what makes Functional Medicine so effective? Like I said, it’s all about looking at the why instead of just the what. So, let’s dive deeper into how this approach works and why it’s helped so many people radically transform their lives by allowing them to reclaim their energy, focus, memory, and overall health.
Why Functional Medicine Works
The secret to why Functional Medicine is such a game-changer is something I’ve already revealed to you. It lies in its ability to uncover and address the root causes of your health challenges, rather than just putting a band-aid on the symptoms.
Let’s take chronic fatigue as an example. In conventional medicine, it unfortunately might be dismissed as stress, laziness, or even depression. But Functional Medicine digs deeper. It asks, ‘Why are you so exhausted?’ Maybe it’s an imbalance in your gut microbiome, a thyroid hormone deficiency, or even long-term exposure to toxins like mold. When we address that root cause (whatever it ends up being in your case), the fatigue often resolves naturally, and you start to feel like yourself again.
And here’s the important part: this approach isn’t guesswork, just throwing spaghetti against the wall to see if it sticks. Functional Medicine is deeply grounded in science and evidence-based practices. Resources like the Institute for Functional Medicine (IFM) continue to advance this research, ensuring that we’re using the best tools available to help you heal and continue to create health.
And, something that makes Functional Medicine truly unique is that it’s completely personalized. Your treatment isn’t based on averages or a one-size-fits-all protocol. It’s built around you. We look at your health history, lifestyle, advanced lab work, and even your genetics to create a plan that fits your body’s specific needs. Two people with similar symptoms might get entirely different treatment plans because their root causes—and their paths to healing—are different.
Another reason this works so well is that it empowers you. Instead of feeling like a passive participant in your care—waiting for test results or medication adjustments—you become an active partner in your healing process. Functional Medicine invites you to make those meaningful changes in your nutrition, your lifestyle, and your daily habits, putting you back in the driver’s seat of your own health.
Take Crystal for example. After working together for just 3 months, this is what she had to say:
“I was 6 months into being a 40 year old, and upon waking, I had chronic aches and pains. I felt awful! People around me and even my primary doctor would say, “Welcome to 40, welcome to old age.” I didn’t want to accept that. My whole body felt out of whack – daily headaches, brain fog, poor memory, mood swings, bloating, and overall fatigue. I was starting to have high cholesterol, and my doctor felt the need to just monitor me and did not offer any other solutions. I didn’t want to wait to see what happened to me.
Dr. Lexi offered tailored healthcare based on my deficiencies and helped put me back together. I no longer wake up with an achy, “old” body. I have the energy and clarity to get through my days. My daily headaches are GONE, my memory is improving, I learned how to properly fuel MY body, and I even lost 10lbs! Those around me have noticed my changes and been amazed by my progression. Most importantly, I feel amazing now and look forward to the next 40 years!”
It’s this personalized, root-cause approach that’s why so many people finally find answers through Functional Medicine. So, let’s dive into how Functional Medicine works its magic to tackle issues like brain fog, memory lapses, and the kind of fatigue that feels like it’s weighing you down every single day. The key is understanding that these symptoms are signals—or clues that your body is out of balance. Functional Medicine takes a deep dive into these signals to uncover what’s really driving them.
How Functional Medicine Addresses Cognitive Decline and Chronic Fatigue
So what are some of the things that tend to drive the dysfunction that results in the symptoms you’re experiencing? Let’s briefly go over some of the key areas that Functional Medicine investigates.
Key Areas Functional Medicine Investigates:
- Gut Health:
First, let’s talk about the gut-brain connection. Did you know your gut and brain are in constant communication? Just to look at one part of it, if your gut microbiome (or your gut bugs) is out of balance—due to things like poor diet, stress, or antibiotics—it can lead to symptoms like brain fog and low energy, not to mention skin issues and throwing off your metabolism. Functional Medicine focuses on restoring gut health to support clearer thinking and better energy. - Chronic Inflammation:
Inflammation is another major player. Chronic inflammation, often caused by processed foods, stress, or hidden infections, creates a toxic environment in your body. This is like having a fire alarm on in your body all the time and can slow down your brain’s ability to process information and leave you feeling completely drained. Reducing inflammation is a foundational step in Functional Medicine to help you feel more focused and energetic. - Hormone Imbalances:
Your hormones—like your thyroid, adrenal, and sex hormones, as well as insulin—are crucial for your energy and cognitive function. When any of these is out of balance, you might feel fatigued, foggy, or even irritable. Functional Medicine works to identify these imbalances and support your body in restoring them naturally. - Toxins and Detoxification:
Environmental toxins, like heavy metals, chemicals, or mold, can interfere with your cells’ ability to produce energy and function properly. Through Functional Medicine, we support your body’s natural detoxification systems to eliminate these toxins and improve your cellular health.
And we address all of these and more in my OAKLEY Method. It’s a step-by-step framework that I personalize for my clients that’s designed to optimize your cellular health. By focusing on cellular healing, we give your body the tools it needs to repair and thrive.
So, by addressing these key areas (and more) and implementing targeted interventions, this Functional Medicine approach offers a comprehensive approach to healing. But it’s not just about the science—it’s about helping you take back control of your health and your life.
So, what’s the next step in your journey? Let’s talk about how you can start exploring Functional Medicine for yourself.
