What Is Functional Medicine?

Functional medicine is a holistic approach to healthcare that addresses the root causes of illness and focuses on healing the whole person rather than just treating symptoms. It considers the unique genetic, environmental, and lifestyle factors contributing to health and well-being.

 Natural science-based medicine aims to restore balance and optimize function by understanding the interconnectedness of the body’s systems. This patient-centered approach utilizes a combination of conventional medicine and evidence-based alternative therapies, emphasizing preventive care and empowering individuals to take an active role in their health. 

With a focus on personalized treatment plans, functional medicine practiced at Medical Direct Care in Clarksville, TN, seeks to improve overall wellness and enhance quality of life. Additionally, functional medicine is a proactive approach. Maintaining a healthy lifestyle limits the potential for chemical, physical, and emotional stressors that lead to disease.

Functional medicine takes an entirely different, client-focused approach which employs five basic principles that make this practice unique and effective for many clients. Here is a quick summary of these five essential precepts:

While human bodies are similar in appearance, all humans are genetically and biochemically unique; natural medicine shifts the focus of care to the person, not the disease, working to support the natural healing mechanism the body produces rather than battling the illness.

functional medicine science-based icon


Contemporary research confirms our bodies are composed of complicated networks and webs of relationships, both internal and external; understanding these relationships provides a better view into the functioning of the body.

The human body is capable of self-regulation and is in fact constantly balancing, adjusting, and correcting inconsistencies within all of the autonomic body systems.

functional medicine auto healing icon


The human body has an incredible ability to heal illnesses and diseases as they arise, while also preventing aging; cold medicines and other over-the-counter drugs are designed to ease the symptoms while the body does its job of curing the illness.



Rather than consider health as a neutral state (i.e., the absence of illness, disease, and discomfort), practitioners of holistic medicine see a state of great vitality to be the epitome of good health.

Benefits of Functional Medicine

The benefits of functional medicine include personalized care that improves overall health and well-being by treating each individual as unique. Amid a common diagnosis, we acknowledge the multi-factorial elements that require an individually designed treatment plan.

A prevention-focused perspective of chronic disease sets the expectation of consistent health as we live active lives even during our latter years. Focusing on finding and addressing the root cause of health issues instead of simply masking symptoms empowers our clients to courageously explore and answer the “why” instead of stopping at “what .” 

Finally, functional medicine promotes a team approach to healthcare and wellness. Instead of separating organs by specialty (i.e., heart specialist, kidney specialist, etc.), the holistic approach supports multidisciplinary conversations that lead to wholeness. We acknowledge that you’ll find that Dr. Fryer and the rest of our team have many different strategies to help you reach optimal health, including dietary changes, exercise, preventive and diagnostic lab work, next steps, and maintenance plans.

Focuses on Root Cause

Functional medicine focuses on identifying the root cause of health concerns rather than solely treating symptoms. Functional medicine aims to promote long-term healing and overall wellness by addressing the underlying imbalances in the body. Many of our clients with chronic conditions progress to the point that prescription medications are no longer necessary.

Personalized Healthcare

Since functional medicine considers each person’s unique genetics and lifestyle, it allows for tailored treatment plans that consider each person’s specific needs and health goals. Considering the client’s goals and desires, individualized health plans are where alternative medicine truly shines.

Proactive Healthcare

Functional medicine is a proactive choice for disease prevention, focusing on identifying and addressing risk factors before they lead to diseases. A personalized and comprehensive approach empowers individuals to control their health and well-being.

This emphasis on proactive preventative care empowers individuals to take an active role in managing their health with the support of our highly trained health and wellness team. This way, patients can experience improved vitality, enhanced quality of life, and a deeper understanding of their well-being.

Our Process

Attend a Highly Informative Meet and Greet Presentation

Learn how functional medicine can revolutionize your view of personal healthcare online during a live or an on-demand webinar, at one of our dinner talks, or at in-person presentations. During this one-hour presentation, you will obtain a behind-the-scenes view of healthcare tactics that may be making or keeping you sick, how Dr. Fryer practices combating these health-destroying practices, how Dr. Fryer implemented functional medicine strategies to regain his health, and various health topics. Asking questions, getting answers, and pursuing personalized care are promoted during these highly interactive sessions. Gaining this knowledge can set you on the path to excellent health by adopting functional medicine over the standard healthcare practices of the day.

Health Evaluation

Once you’ve decided functional medicine is right for you, the next step is for Dr. Fryer to determine if you are a good fit for Medical Direct Care. Dr. Fryer begins by performing a comprehensive evaluation based on an extensive health questionnaire the client completes before the consultation. During the 60-minute conversation, Dr. Fryer recommends the best course of action that will assist the client in obtaining their desired goals.

Healthcare Plan

After the client accepts the recommendations, developing a personalized treatment plan is the next step. This plan is the roadmap for the client’s health and wellness adventure.

Based on the evaluation results, we create a personalized healthcare plan that may include preventive lab work, dietary modifications, lifestyle changes, targeted supplementation, and other natural therapies to address the root cause of your health concerns.

Strategically Placed Wellness Appointments & Support

The personalized wellness roadmap will include strategically placed wellness appointments to monitor your progress closely. During these visits, asking questions, obtaining answers, evaluating progress, making adjustments, and strategizing are common activities. In addition to medical support, each client can access weekly 1:1 coaching sessions with a certified health and wellness coach. During these sessions, you will receive tips and tricks to implement the recommendations provided by the health providers. These sessions also assist you in moving from acquiring knowledge to implementing knowledge to transforming your life. In addition, monthly classes on various topics and weekly Tai Chi Qi Gong classes are available.

The History of Functional Medicine

Functional medicine has its roots in traditional medicine practices such as Ayurveda and Chinese medicine. In the 1990s, a group of forward-thinking physicians and researchers started questioning the standard healthcare model and discovering new ways of understanding and treating diseases. 

Consequently, they recognized that each person is unique and that genetics, lifestyle, and environment play a significant role in their health. This mindset shift led to the development of functional medicine, which combines the latest scientific research with a personalized approach to healthcare. Today, it is gaining popularity as more and more people seek alternative and preventative methods for improving their well-being.

Over the years, functional medicine has gained momentum and recognition as a legitimate approach to patient care. It has caught the attention of healthcare professionals, researchers, and patients alike due to its focus on addressing the underlying causes of illnesses rather than merely managing symptoms. 

Functional medicine looks beyond the conventional one-size-fits-all treatments and aims to create personalized and integrative healthcare plans. The increasing body of research supporting functional medicine and its success stories have made it a trusted alternative to the traditional healthcare model. As functional medicine continues to evolve, it promises to reshape how we approach and practice medicine, placing the patient’s well-being and long-term health at the forefront.

Integrative Approaches to Functional Medicine

The Holistic Approach in Functional Medicine

Functional medicine embraces a holistic approach, considering the interconnectedness of the body, mind, and spirit. It recognizes that imbalances in one area can impact the whole person and strives to restore balance and promote healing on all levels. It considers the interconnectedness of various bodily systems and supports overall health and wellness. 

Functional medicine seeks to create individualized treatment plans that restore balance and optimize the body’s natural healing abilities by considering a person’s unique genetic makeup, lifestyle, and environmental influences. This approach emphasizes the importance of nutrition, exercise, stress management, and other lifestyle factors in preventing and managing chronic diseases. By taking a whole-person approach, functional medicine aims to provide comprehensive and personalized care to support long-term health and well-being.

Combining Traditional and Alternative Medicine

What does a functional medicine doctor do?

Doctors pursue functional medicine in their post-graduate studies. Functional medicine doctors use lab testing to understand genetic, biochemical, and lifestyle components to create individualized treatment plans.


Can functional doctors write prescriptions?

Absolutely! Functional doctors are real doctors and we do write prescriptions when necessary. Just because traditional medicine is a disease-focused approach to health and functional medicine is a patient-centered approach doesn’t mean that we don’t write medications for ailments. The difference is personalized prescriptions.


Does functional medicine really work?

Yes, which is backed by mountains of research and patient results. Functional medicine focuses on the underlying causes of health problems and is a proactive healthcare approach.


What is the difference between a functional doctor and a regular doctor?

A functional medicine doctor takes a different approach than a traditional doctor. While a traditional doctor will primarily focus and treat a given condition, a functional medicine doctor will take a holistic approach to healthcare. We take into consideration the entire body when diagnosing and treating patients. 


What’s included in your functional medicine program?

Pre-Program Services:

Thorough personalized case evaluation to include research, review of labs, and a customized program design proposal

During the Program Services:

Access to an exclusive MDC Wellness Education System accessed through a wellness portal; hard copy of the manual that accompanies the online system; live classes; recordings of the live classes; Dr. Appointments (virtual and live); email support; Telephone support; private messaging; Coaching sessions by a board-certified life, health, and wellness coach

After the Program Services:

After a client completes their health and wellness program of 3 or 6 months they are given the option to further refine their personalized health and wellness plan through a VIP program that utilizes P.R.E.S.S. 360 tm,  a proprietary system specifically developed for the graduates by an inhouse certified life, health, and wellness coach. This six month program is a deep dive into applying the information received in the wellness program so that the client is equipped to create a personalized, custom-designed health and wellness system that leads to a transformed life in a systematic done-with-you process.


Services are also provided for legacy leavers who desire to upgrade their health and wellness legacy.  Many parents, grandparents, and great grandparents desire to apply their new found knowledge about health and wellness and share the information with their posterity as a priceless legacy that is better than gold.  We assist these individuals by equipping them with the training necessary to become the empowered elders that they are in the realm of health and wellness.  Our desire is to leave a legacy of multigenerational wholeness of spirit, mind, and body.


In addition to the VIP program there is ongoing support provided to the wellness graduates to foster community through education, encouragement, and empowerment opportunities.


How much is the functional medicine program investment?

The investment is determined by the need and the goals of the client.  After a thorough evaluation and an extensive 60 min interview with the potential wellness participant, the investment is determined that will yield the client’s desired results. 


Does insurance cover functional medicine in your office?

Although we accept insurance, insurance does not accept us.  Our goal as functional medicine providers is to prevent illness and to maximize health.  Insurance does not share in our perspective and only invest in the client’s health when a disease has already been established.  That being said, we utilize insurance to cover everything that it will cover as we assist in helping clients restore their health to the best possible level.


Is lab testing covered by insurance?

There are two types of labs: 1. Diagnostic and 2. Preventive labs. Diagnostic labs are usually utilized to determine the extent of an existing disease. For example a HbA1C if often used to determine or monitor blood glucose levels in the instance this test is serving a diagnostic purpose.  However, if I wanted to assess the reason why I may have a propensity for diabetes so as to prevent my pre-diabetic situation from becoming worse that same HbA1C would not be covered by insurance. I would have to pay out of pocket because I am not a diabetic yet. Therefore once we educate our clients on the value of purchasing preventive testing and acting proactively for their health and the expense of waiting for a disease to occur with additional health challenges, our clients choose to prioritize their health which is priceless.


Do you offer financing services?

Of course.  Based upon the credit score of the client we have partnered with a number of financial institutions to assist clients in prioritizing their health.  Care credit is one of these financial institutions that allows you to pay the office visits, lab testing, and nutritional supplement costs over a period of 12 months with same as cash options available.


Are HSA or FSA accounts accepted?

Both HSA and FSA accounts are accepted by our office but check with your particular plan to see if our services are covered by their plans.


Can you see patients in other cities?

Yes, as a wellness center we are able to offer our services by telemedicine in other cities, states, and countries however our only language is English.


How is lab testing performed?

Testing services have gotten very sophisticated over the years that we are able to mail test kits to our clients and they have all of the materials, information, and resources to simply collect the specimen and return it to the respective labs in a postage-paid container.  Once the specimen is received by the laboratory and processed, we are notified, we in turn notify the client to establish a lab review visit, and then we conduct the lab review live or via telemedicine.
