Chemical Intolerance in Primary Care Settings

May 26, 2017

This study examines the prevalence and clinical characteristics of chemical intolerance in a sample of primary care clinic patients. A total of 400 patients were recruited from 2 family medicine clinic waiting rooms in San Antonio, Texas. Patients completed the validated Quick Environmental Exposure and Sensitivity Inventory (QEESI) to assess chemical intolerance Overall, 20.3% of […]


Chemical Intolerance – Comparing Gulf War Veterans & Other Affected Groups

May 26, 2017

Up to one-third of the U.S. population reported being either “especially” or “unusually” intolerant to certain chemicals, with about 5% reporting physician-diagnosed chemical intolerance (CI). Dr. Claudia Miller and colleagues developed the Environmental Exposure and Sensitivity Inventory (EESI), a validated tool designed to assist researchers and clinicians in evaluating patients and populations for CI. In this study, Drs. Miller and Prihoda applied the EESI to five different population groups for comparison. Groups were CI patients (1) who did or (2) did not attribute onset of their illness to a specific exposure event, (3) patients with surgically implanted devices, (4) Gulf War veterans (GWV), and (5) controls. All of the exposure groups reported similar multi-system symptoms and new onset chemical, food and drug intolerances despite having different initiating exposures.
