Dr Hagmeyer Explains Functional Medicine and The BIG Picture

“When Experience Makes All The Difference”

People from all over the world seek the help and expertise of Dr Hagmeyer for their chronic health problems. Dr Hagmeyer’s Holistic “BIG PICTURE” approach is what sets him aside from many Integrative, Holistic and Functional Medicine Physicians.

While many physicians claim to be “Holistic” and “Treat the person,” many of these physicians do a disservice to their patients by either not running the proper testing or by not monitoring a patients progress with retesting.

Dr Hagmeyer firmly believes that If your not testing, your guessing. Dr Hagmeyer is not a big fan of guessing about your health.

Having over 20 years of experience in natural and alternative health, Dr Hagmeyer has a passion for helping people who suffer with digestive disorders, food allergies, Leaky gut, SIBO, Crohn’s, Celiac disease, Gluten Intolerance, Candida, Parasites and Acid Reflux. Dr Hagmeyer also has a passion for helping patients suffering with Autoimmune disorders, hormone imbalances( PMS, PCOS, Endometriosis, Infertility) and neurodegenerative diseases such as MS, Parkinson’s and dementia.

Dr Hagmeyer Functional Medicine Approach

Step I- Case Review-

This is where we learn about our patient. Applicants will mail in all paperwork prior prior to their case review. This gives Dr Hagmeyer the time he needs to thoroughly understand your health problem and some of the hidden causes that may have been overlooked. This also gives Dr Hagmeyer the opportunity to see what has been done, what has not been done so that we can avoid any duplicate testing.

Your story is the most important component to your case. To understand your story we will need several key elements. Existing blood work, Health History Narrative (3-5 page typed), New patient paperwork and any other testing you feel that will be helpful to Dr Hagmeyer in understanding your case.

Step II-Testing-

Upon receiving your records, Dr Hagmeyer will review them and determine what additional testing will appropriate in your case. There are often many “layers” to chronic health problems.  These layers may include Hormones, Adrenal, GI, Infection, Immune, Dietary, Methylation, Detoxification, vitamin/mineral imbalances.

The functional and metabolic testing serves an integral part and a compass that helps Dr Hagmeyer understand “WHY” you feel the way you do.

While many holistic and Integrative doctors get “hung up” on one area ie Hormones, Gut, Adrenal glands, they miss the “BIG PICTURE”. Patients from all over the world contact Dr Hagmeyer because of the comprehensive testing and methodical treatment taken. Advanced Metabolic and Functional Testing

Step III Customized Nutrition-

Once Dr Hagmeyer understands the causes behind your Metabolic health problem, Dr Hagmeyer will determine a course of action and treatment program. Treatment is individualized and customized to each patients test results.

Dr Hagmeyer does not have a “cookie cutter” approach to helping his patients reclaim their lives. Instead, a customized meal plan and supplement protocol will be created for you based on the “glitches” in your bodies biochemistry.

Dr Hagmeyer will often pair you up with one of his registered dietitians or holistic nutritionists to further support your healing journey. This ensures you don’t feel overwhelmed with all of the dietary and lifestyle changes to be made. We want you to have a life changing experience with our office and our team members. We are here for you every step of the way.

Step IV Check Points

Your personalized program is monitored every step of the way. You will never feel alone. One of the complaints we often hear from patients within the US and international, is that they feel like they have no guidance or direction.

Whoever they worked with in the past didn’t have a plan for recovery. This is why we have developed strategic check points throughout your program.

These check points occur at two weeks, six weeks and ten weeks and are designed to monitor your progress, maintain accountability and ensure your success every step of the way. These include Metabolic Assessment Forms, Neurological Health Forms, Dietary Food Journaling and Progress questionnaires all of which maximize the effectiveness of your Program.

Step V Lifestyle Education

You will receive health education as part of your program, along with several opportunities to attend workshops, Webinars for our international patients, Videos only accessible to our patients.  Lifestyle education ensures your long term success.
