Unseen Drips and Total Toxic Burden: Bridging Medicine and Building Science
When unexplained symptoms appear alongside water damage, persistent musty odors, or high indoor humidity, the investigation may need to extend beyond the person to the building itself. And because people sharing the same home can experience very different symptoms, identifying a possible environmental problem is rarely as simple as looking at one person or taking one test.
Dr. Imran Khan is an internal medicine physician with training in functional medicine whose practice includes patients concerned about mold and environmental exposures. In this conversation, he and John Bohde connect the medical and building sides of mold investigation, from symptom patterns and exposure history to moisture problems, HVAC systems, testing, source control, remediation, and recovery. Dr. Khan also explains why his clinical approach prioritizes reducing ongoing exposure before detoxification and why improvement after remediation may take time.
In this episode, you’ll discover:
Why changes in symptoms after moving into a new home, spending time away, or encountering water damage, musty odors, or high humidity can provide clues worth investigating
How moisture and HVAC problems can contribute to hidden mold concerns, and why identifying and correcting the source is different from simply repairing or covering visible damage
Why Dr. Khan considers source control an important step before detoxification, and why symptom patterns and recovery timelines can differ significantly from person to person
This episode is for anyone experiencing unexplained symptoms alongside concerns about their home or workplace, families whose members seem to respond differently to the same environment, and people trying to understand how medical care, building investigation, remediation, and recovery may fit together.
