New Services

My approach to integrative health care is to first make sure that the most basic, fundamental physiological requirements for optimal health are in place. Thyroid hormone production and regulation of metabolism at the cellular level are prime examples of fundamental requirements for optimal health. If you have poor thyroid hormone regulation, symptoms like those on my Self-Tests often occur. When you normalize thyroid hormone regulation and restore your metabolism, these "mysterious symptoms" usually disappear within a few months.  The understanding and application of the principles of fundamental physiology were the reasons that you restored your health. 

Several months ago I received a call that opened the door to another "fundamental physiology" way to help people.  Dr. Peter Litchfield, Ph.D., President of Better Physiology, LTD and Sandra Reamer, MFA,  Executive Director of Behavioral Physiology Institute, LLC introduced me to overbreathing, or hypocapnia, which refers to a deficiency of carbon dioxide (CO2) in the blood and other extracellular fluids.  Their focus is on the integration of textbook physiology and behavioral science of breathing
Learned overbreathing, also known as "behavioral hypocapnia", occurs when you exhale too much CO2 and create a deficiency.  Proper allocation of CO2 is essential to keep our pH, electrolytes, blood flow, kidney function, and hemoglobin composition balanced.  A deficit of CO2 may cause health and performance issues including anxiety, panic attacks, anger, stress states, or physical symptoms such as high blood pressure, asthma, pain, muscle spasms, and fatigue. Attention, memory, learning, and task performance problems are common in people suffering from hypocapnia. 
This collection of symptoms of hypocapnia overlaps with many of those associated with poor thyroid regulation, suboptimal adrenal gland function, chronic fatigue, and fibromyalgia. And, I can also see how hypocapnia may mimic or aggravate some of the symptoms of overstimulation from excessive doses of thyroid hormone.
We usually don't notice our breathing unless we're exercising vigorously or have asthma or chronic lung disease. Some people receive instruction about breathing in an exercise, meditation, or yoga class.  Much of this education is based on pseudoscience, misinformation, and ignorance and is not consistent with respiratory physiology.
Breathing normally occurs as a reflexive action:  we don't have to think about it, it just happens.  For a variety of reasons, between 10% and 25% of the population learns to override this reflex and overbreathe.  In major urban areas in the US, 60% of ambulance runs are the direct consequence of symptoms caused, triggered, perpetuated, or exacerbated by learned hypocapnia.
The only way to know if you experience hypocapnia is to measure your exhaled CO2.  You cannot tell if someone is overbreathing based on their respiratory rate or watching the expansion of their chest.  I use the same technology to measure your CO2 levels that's used in surgery or critical care environments in hospitals. 
CapnoLearning, developed by the Behavioral Physiology Institute, is the system of behavioral analysis, behavior modification, biofeedback, cognitive learning, and awareness training to discover and correct behavioral hypocapnia.
Your exploration of possible overbreathing begins with a Breathing Assessment over the telephone to discuss your health and performance issues that could relate to hypocapnia. Your answers may lead us to schedule a Breathing Evaluation to actually measure your exhaled CO2 level and gain self-awareness of your breathing behavior.  If we find that you have behavioral hypocapnia, you can learn how to self-regulate your CO2 to improve your health and performance. CapnoLearning classes for self-exploration, awareness, and education are available.  
This course includes 8 hours of class time and are limited to 8 participants.
Call 303-413-9100 for more information, to sign up for a group class, or to schedule your private session.  

The Center for Metabolic Health, LLC has become Fundamental Physiology, LLC 

Since I've added another "fundamental physiology" service I decided to give my clinic a more descriptive name. The Center for Metabolic Health, LLC is now called  "Fundamental Physiology, LLC".  Please update the name and my new email address in your contact lists and databases. 
My new email address is: 
It is active and able to receive email.
Please continue to send your snail mail to:
Fundamental Physiology, LLC
P.O. Box 17131, Boulder, CO 80308 
My new physical address is:
1942 Broadway, Suite 314, Boulder, CO 80308
My website address will soon change to and I'll send out a newsletter to let you know when this is active.  

New Receptionists!

I'm delighted to announce that either Candice or Julia will be speaking with you when you call Fundamental Physiology, LLC during regular business hours.  They can give you general information about services and clinic policies.  As always, if you need to discuss specifics of your health care you will need to schedule an appointment to speak with me. 
You will be able to speak with Candice or Julia  Monday through Friday, 7:30 am through 5:30 pm, Mountain Time Zone.  Voice mail is available to take your message if you call outside those hours.  
What's on your mind?  My goal with my newsletters is to give you information that can help you get healthy and stay healthy.  Please feel free to email your questions or topics of interest so I can address them for you.
Kind regards, 

Dr. Gina S. Honeyman
