Gastroenterology, Celiac and Food Allergies & Sensitivities

Dr. Pearson's Integrative Gastroenterology

 

Dr. Pearson is a leading integrative gastroenterologist and pioneer in integrative gastroenterology diagnosis and management.  He has created new screening, monitoring, and treatment protocols that have changed lives for thousands of patients.    


Dr. Pearson was the Chair of the Medical Advisory Board of the Celiac Sprue Association for five years while he practiced in Tucson, Arizona.  Dr. Pearson provided training to other physicians and healthcare professionals on the diagnosis and management of celiac disease, as well as outreach programs such as the annual free celiac screening fair.  


Dr. Pearson was the medical director of the first U.S. free celiac screening fair that included comprehensive celiac screening, including the newer Deaminated Gliadin Peptide (DGP) testing.  Dr. Pearson also provided lectures on celiac disease, food allergies, and food sensitivities.  


 In addition to celiac disease, Dr. Pearson is a leading physician in Ulcerative Colitis, Crohn's disease, and other autoimmune conditions, including Hashimoto's thyroidits, Rheumatoid Arthritis, and Lupus.  Since all autoimmune conditions are immunological conditions and since the small intestines houses over 75% of our immune system, he has created holistic treatment plans treating the root cause of disease, while treating the whole person.     


Dr. Pearson is one of the first physicians in the U.S. to use blood IgE Food Allergy and IgG Food Sensitivity testing with patients.  Since over 75% of our immune system is in our small intestines, he believes food allergies and sensitivities should be tested in patients with GI complaints, autoimmune disease and other chronic illnesses.  Allergies and sensitivities can wear down an immune system and cause an selective immunoglobulin deficiency or cause a hyperreaction of the immune system, as seen in autoimmune conditions.  In chronic disease, you want to remove as many obstacles to cure as you can to help the body heal itself.     


Dr. Pearson developed a PsychoNeuroGastroEndoImmunology (PNGEI) model describing the interdependence of these systems and their role in health and disease. Dr. Pearson's model emphasizes the tremendous impact the intestinal tract has on our nervous, immune, and hormone systems - as it contains 80% of our serotonin and over 75% of our immune system. Dr. Pearson's PNGEI approach has helped patients recover from chronic illnesses including psychiatric issues, immune dysfunction, and nervous system disorders.
