What is Functional Medicine? A Comprehensive Guide to Root-Cause Healing

At SALT Health, we don’t settle for band-aid fixes. We believe in getting to the heart of the matter—why your body feels the way it does, why you’re not thriving, and how to help you live life healthy. This is where functional medicine comes in.

Functional medicine is revolutionizing healthcare by focusing on the root causes of illness rather than just treating symptoms. It offers a comprehensive, personalized approach to health, considering every aspect of an individual’s life, from diet and exercise to genetics and environmental factors. As Dr. Aunna Herbst, Co-Founder & Chief Medical Officer at SALT Health, explains, “Functional medicine helps optimize functions by looking at biochemistry, genetics, environment, and lifestyle. It’s all about restoring balance in the body to improve overall well-being.”

At its core, functional medicine empowers individuals to take control of their well-being through personalized, proactive care. It’s not just healthcare—it’s life care.

What is Functional Medicine?

Functional medicine is a systems-based approach to health that prioritizes finding the root causes of illness and imbalances. We’re not just treating what’s wrong—we’re asking, “Why is this happening in the first place?”

Functional medicine is often described as personalized medicine. Unlike traditional care models that apply generalized treatments, functional medicine tailors its approach to the unique needs of each individual. 

This model examines how factors like genetics, biochemistry, nutrition, and environment interact to impact health. As we often explain to patients, functional medicine is about optimizing how your body functions as a whole, not just addressing parts in isolation. It’s about balance—homeostasis—and how we can support your body’s natural ability to heal.

“When you visit a functional medicine provider, the goal is to uncover your body’s specific needs. Whether it’s addressing nutrient deficiencies, supporting detoxification, or understanding genetic predispositions, functional medicine ensures every patient’s care is as unique as their DNA.” – Dr. Aunna Herbst

This approach makes functional medicine a powerful tool for achieving optimal health. It addresses chronic conditions, improves quality of life, and focuses on prevention through proactive care.

How Functional Medicine Differs from Conventional Care

A Holistic Perspective

Traditional medicine is great for acute issues—think broken bones or infections. But when it comes to chronic conditions like diabetes, autoimmune disorders, or unexplained fatigue, functional medicine shines by addressing the underlying imbalances that drive these issues.

Functional medicine asks questions like:

  • What lifestyle patterns or nutritional gaps could be contributing?
  • How is the body’s system responding to environmental stressors?
  • Are there genetic variations at play that we can support?

Why Root-Cause Matters

Dr. Herbst explains, “When we focus on root causes, we’re no longer guessing. We’re addressing the actual reasons behind symptoms, which allows for more precise, effective care.”

Conventional medicine often stops at treating symptoms. For example, if you’re exhausted, you might be told to “get more sleep.” Functional medicine asks why you’re so tired. Is it adrenal fatigue? A nutrient deficiency? Chronic inflammation? We dig deep to find the answer.

Traditional medicine tends to treat issues in silos—your digestive health here, your mental health there. Functional medicine looks at how everything is connected to see the bigger picture of your overall health and wellness.

This approach isn’t about handing you a prescription and sending you on your way. It’s about helping you understand your body, so you can take charge of your health.

Who Benefits from Functional Medicine?

Functional medicine isn’t exclusive to those with chronic illnesses. It’s for anyone who wants to take control of their health, whether that means managing a specific condition or simply feeling better day-to-day.

At SALT Health, we’ve seen functional medicine transform lives by addressing:

  • Chronic Fatigue: Finding and addressing hidden stressors like adrenal burnout or sleep disorders.
  • Digestive Disorders: Uncovering triggers for IBS, Crohn’s, or other gut issues.
  • Hormonal Imbalances: Supporting thyroid health, PCOS, or menopause-related concerns.
  • Mental Health Challenges: Targeting the root causes of anxiety, depression, and ADHD.
  • Autoimmune Conditions: Identifying and reducing inflammatory triggers.
  • Metabolic Health: Managing diabetes, cardiovascular health, or weight issues.

The Science Behind Functional Medicine

Functional medicine is built on a foundation of cutting-edge science, blending knowledge from biochemistry, physiology, and genetics to uncover how the body’s systems interact. Rather than focusing on symptoms in isolation, it seeks to understand the intricate connections that drive health and disease.

1. Biochemistry: The Body’s Chemical Symphony

Every process in the body, from energy production to immune response, relies on the delicate balance of biochemical interactions. Nutrients, hormones, and enzymes work together to keep systems running smoothly, but deficiencies, imbalances, or disruptions can lead to symptoms or chronic conditions.

For example:

  • A deficiency in magnesium might result in fatigue or muscle cramps because it’s a cofactor in over 300 enzymatic reactions.
  • Hormonal imbalances, such as low thyroid hormones, can manifest as weight gain, hair loss, or brain fog.

By understanding these processes, functional medicine can pinpoint what’s missing and restore harmony.

2. Pathophysiology: How Systems Go Off Track

Pathophysiology combines the study of normal bodily functions (physiology) with the mechanisms of disease (pathology). This lens helps us understand how chronic inflammation, poor detoxification, or immune dysfunction can contribute to health challenges.

Take detoxification, for instance. If the liver struggles to clear toxins due to nutrient deficiencies or environmental overload, those toxins can accumulate and cause systemic issues like fatigue, brain fog, or skin problems. Functional medicine identifies and supports these overwhelmed pathways to restore balance.

3. Genomics: Understanding Your Unique Genetic Blueprint

Genomics examines your entire genetic makeup to identify how your DNA influences your health, risk factors, and how your body responds to lifestyle choices. While your genes don’t change, understanding your genomic profile can help you make targeted decisions to support optimal health.

For example: Genomic insights can reveal a higher predisposition to inflammation, allowing you to take proactive steps—like managing stress or adjusting your diet—to reduce disease risk. You may discover specific nutrient needs or sensitivities, enabling you to personalize your nutrition plan to better support your body’s natural functions.

Dr. Herbst captures the beauty of functional medicine, saying, “It’s where we blend data-driven diagnostics with clinical intuition and patient collaboration. By uncovering how genes interact with lifestyle, we empower patients to take control of their health.”

What Makes Functional Medicine Unique?

Functional medicine stands apart by prioritizing a personalized, patient-centered approach that addresses root causes rather than just symptoms. Here’s how it redefines healthcare:

1. Time and Attention: The Gift of Listening

Functional medicine visits are intentionally longer—often lasting 30 minutes to an hour—because understanding your full story is essential to providing truly personalized care. Our providers take the time to explore your health history, lifestyle, and even childhood experiences to uncover patterns and root causes. This level of attention simply isn’t possible in the traditional model, where appointments often last just 7 to 10 minutes. By taking a deeper, more thoughtful approach, we ensure nothing is overlooked—because your body tells a story, and when we take the time to listen, we can find the answers.

2. Personalization: No One-Size-Fits-All Care

Every individual’s health journey is unique. Functional medicine tailors recommendations to your specific needs, based on:

  • Your genetic makeup
  • Your environmental exposures
  • Your current lifestyle and health goals

For example, two people with fatigue might have entirely different root causes—one driven by nutrient deficiencies and the other by chronic stress. Functional medicine ensures their care plans are as unique as their DNA.

3. Integration: Bridging the Gap Between Care Models

Functional medicine complements conventional medicine, creating a cohesive approach to health. It doesn’t reject traditional care but enhances it by focusing on prevention and addressing underlying causes.

For example:

  • A patient with heart disease might receive functional medicine support for optimizing cholesterol through diet and lifestyle while continuing necessary medications.
  • Functional medicine also works with specialists to provide actionable insights, such as genomic data that guides anesthesia choices or medication sensitivities.

Dr. Herbst describes it best: “Functional medicine isn’t about replacing conventional care; it’s about elevating it by creating a comprehensive, proactive approach to health.”

Why Patients Choose Functional Medicine

Patients often come to us feeling unheard or frustrated after years of bouncing from one specialist to another. Here’s what they say after trying functional medicine:

  • “For the first time, someone connected the dots.”
  • “I finally understand why I’ve been feeling this way.”
  • “This isn’t just about managing my condition—it’s about healing.”

Overcoming Common Concerns

Some people hesitate to try functional medicine, worrying that it might feel “too alternative” or that it diverges from the trusted approaches of conventional care. But functional medicine isn’t about replacing one system with another—it’s about integration and optimization.

This isn’t about choosing between functional and conventional medicine. It’s about bringing the best of both together to create a comprehensive approach that works for you. Functional medicine complements traditional healthcare by digging deeper into the root causes of health issues, focusing on prevention, and offering personalized solutions.

Here are a few ways functional medicine bridges the gap:

  • Evidence-Based Practices: Functional medicine relies on peer-reviewed research and clinically validated testing, ensuring the care you receive is grounded in science. From advanced lab work to genomics, the tools used in functional medicine align with the highest medical standards.
  • Collaboration, Not Competition: Functional medicine providers often work alongside conventional doctors. For example, a functional medicine provider might collaborate with a cardiologist to address inflammation in heart health or with an endocrinologist to explore hormonal imbalances.
  • A Focus on Whole-Person Care: Instead of treating just symptoms, functional medicine considers factors like nutrition, lifestyle, and genetics. This whole-person approach helps patients understand the “why” behind their conditions, empowering them to take an active role in their health.

For patients new to this approach, Dr. Herbst often shares this analogy: “Think of functional medicine as the missing piece of the puzzle. It doesn’t replace the rest—it completes the picture, allowing us to create a more effective, personalized care plan.”

By integrating functional medicine with traditional care, patients can benefit from the strengths of both approaches. It’s not about alternative versus conventional—it’s about finding what works best for each individual.

Why Functional Medicine Matters Now More Than Ever

In today’s fast-paced world, the traditional healthcare system often feels rushed and reactive. Patients may leave appointments with more questions than answers, feeling like their unique needs weren’t truly addressed. Functional medicine offers a different approach—one that’s thoughtful, proactive, and deeply personalized.

Dr. Herbst explains it this way:

“A diagnosis is just the beginning, not the end. The real questions are: Why is this happening, and how can I change it? Functional medicine helps you answer those questions and empowers you to take control of your health.”

This approach isn’t just about managing symptoms—it’s about understanding the underlying causes of health challenges and creating strategies to restore balance and vitality. By addressing root issues, functional medicine helps patients take ownership of their health journey, offering hope and clarity in an often overwhelming healthcare landscape.
