Detailed definition
The shift from "HRT" to "MHT" is essentially terminological — both refer to the same intervention of replacing estrogen and (when appropriate) progesterone. NAMS, the International Menopause Society, the British Menopause Society, and other groups now prefer MHT because it frames the therapy as supporting a normal physiological transition rather than treating a deficiency disease. In practice, both terms are used interchangeably in patient-facing communication, and "HRT" remains far more recognized by lay audiences.
Why it matters in menopause
Patients searching for "HRT" and providers writing in current professional literature using "MHT" are talking about the same thing. The terminology should not be a barrier to care.
