What You Need to Know About Functional Medicine

The foundation of East-West Medicine is rooted in Functional Medicine.  Although Functional Medicine is a new approach to Western Medicine, it is a practice that has been perfected by Eastern Medicine with over 2000 years of empirical clinical evidence in writing.  By definition, Functional Medicine is the practice of medicine where diagnoses and treatments focus on the whole body and consider the harmonization of all organ systems to produce optimal health, healing and longevity.  Dr. Barrett builds upon the Functional Foundation of Eastern Medicine with the many advantages of Western Medicine for a unique approach to medicine that has cured many illnesses that have been otherwise deemed idiopathic and written off as due to aging.

While Western Functional Medicine offers the advantage of laboratory testing and diagnoses after a symptom presents itself, Eastern Functional Medicine has the advantage of Traditional Diagnostic Methods based on inquiry, observation and palpation that can identify medical problems and weaknesses before symptoms manifest.  Traditional Diagnostic Methods can offer empirical based clinical data regarding circulation, lymphatic drainage, quality of blood, peripheral and somatic nerve function, health of gut microbiome, functions of all organs, stress levels, levels of inflammation and overall global strength of an individual’s body, mind and spirt.  For example, an individual may suffer from fatigue due to due to digestive malabsorption caused by stress.  However, the individual may not show signs of malabsorption with symptoms or laboratory tests.  Also, the individual may be so accustomed to living with stress that they may not be aware they are stressed.  A Traditional Diagnosis will empirically identify clinical evidence of stress and malabsorption upon observation.  With Dr. Barrett’s years of clinical experience, the accuracy of his Traditional Diagnostic Methods is superior to most.  Many times his East-West approach to Functional Medicine can diagnose, treat and cure health issues before lab tests are completed.  However, although Eastern Functional Medicine has many advantages, there are cases where the Western approach is helpful.  Given the wisdom of his experience, Dr. Barrett can guide you through the process with confidence.

How Are Modern Functional Medicine and Traditional Chinese Medicine Different

Modern functional medicine offers more laboratory manufactured solutions while Acupuncture and Traditional Chinese Medicine focus on all natural solutions. Laboratory produced manufactured solutions may offer the answer to an otherwise untreatable health issue. However, the individual may become dependent on such substance as they may eliminate symptoms but not the underlying cause. Whereas, Acupuncture and Traditional Chinese Medicine focus on increasing the body, mind and spirit of an individual to be self sustaining and resolve health issues from within and thus eliminate a constant dependency.

When is Modern Functional Medicine the Best Solution?

Acupuncture and Traditional Chinese Medicine focus on naturally optimizing your health and wellness in accordance with your genetic gifts at birth. For most people this puts them on top of their game in terms of health and wellness. However, for some this is not enough. Perhaps their genetic makeup constitutes bodily functions and dietary tolerance for a different environment and diet. This is common today with mass global migration. Until now the only solutions in these situations would have been chemically engineered pharmaceutical drugs which usually come with many side effects that may cause one to wonder if they are worth it. However, over the last 30 years much progress has been made in identifying and diagnosing genetic voids or weaknesses along with related non-pharmaceutical produced supplements to treat the symptoms of such voids without the side effects. This is aspect of functional medicine is known as known as genome medicine. Truly progress has been made.

When Will Dr Barrett Prescribe a Modern Functional Medicine Non-Pharmaceutical Produced Supplement for a Genetic Void or Weakness?

Given that most healthcare solutions with Acupuncture and Traditional Chinese Medicine are designed to be self sustainable through diet and lifestyle without dependencies on substances natural or otherwise, Dr. Barrett prefers to reserve other supplements to address a genetic void only after a patient has plateaued and a true void can be identified as being the root of the cause.

How Does It Work?

First a patient will be given a saliva test which will be used to identify a genetic DNA profile. This profile can then be analyzed for appropriate voids that may lead the the health issue being addressed. After the analysis an appropriate supplement can be designed and prescribed to address any genetic void and resolve the health issue.

What Symptoms are Most Commonly Addressed Through Genomics?

The most common symptoms that ultimately may require a genomic solution are as Obsessive Compulsive Disorder and Attention Deficit Disorder.
