In the late 1990s, the Minnesota Board of Medicine audited the practice of Keith W. Sehnert, M.D. and concluded: (a) “almost without exception,” his evaluations, diagnoses, and treatments were the same for all of the 27 cases it reviewed, (b) his concept of medical illness and pathophysiology revolved “almost exclusively” around candidiasis sensitivity syndrome, and (c) he identified “three interlocking ‘clusters’ of problems common to his patients: (i) systemic candida infections; food allergies/intolerances; and hypothyroidism.” In 1998, he board ordered him to stop seeing patients for at least three years, after which he could reapply foir licensure if he could prove to the board that was competent to resume practice [13]. However, he died in 1999.

In 2019, the Medical Board of California reprimanded John Edward Humiston, M.D. for negligence in the care of two patients. In one of the cases, he prescribed alleged anti-Candida supplement protocol [14].

The Bottom Line

I believe that practitioners who diagnose nonexistent “yeast problems” should have their licenses revoked. Some apply this diagnosis to nearly every patient they see.
