From teaching to medicine
Before becoming a physician, Sylvie Demers taught science at the secondary level (biology, chemistry and physics) and the college level (various biology courses) for more than four years in her hometown of Victoriaville; she has held a teaching certificate since 1986.
After completing her medical degree at Université Laval in 1996 and her family-medicine residency at Université de Sherbrooke in 1998, at the age of 41, she practised as a family physician with a highly varied practice: emergency, hospitalization, psychiatry, medico-legal medicine and teaching. She practised in Ville-Marie (Témiscamingue) and in Victoriaville, and has practised in Gatineau since early July 2004. Additional training in psychiatry and in law allowed her to practise psychiatry at the Centre Hospitalier Pierre-Janet, in Gatineau.
Biologist and researcher
Also a biologist and researcher, she completed a doctorate in experimental medicine at Université Laval in 2003, with a specialization in human molecular genetics.
The Centre ménopause-andropause Outaouais
In 2004, Dr. Demers decided to deepen her knowledge of sex hormones on her own and to advance scientific knowledge in the field. In January 2005, she founded the Centre ménopause-andropause Outaouais, in Gatineau, whose primary mission is to gain recognition for the many benefits of sex hormones to well-being and health. Since then, thousands of women and men have been or are being treated for a wide range of health problems related to sex hormones. She has developed her own expertise in hormone dosing — an invaluable tool for improving the overall care of women’s and men’s health.
Pioneer, author and speaker
A true pioneer in her field, a renowned speaker and the author of scientific publications, she is the recipient of several grants and distinctions, including, in 1996, the French Government award for the excellence of her results in medicine.
Her first book, the best-seller “Hormones au féminin : Repensez votre santé” (Les Éditions de l’Homme, 2008 and 2009), has been published in France since April 2011 and was updated in 2013 under the title “Hormones et Ménopause”; that version, translated into Dutch, has appeared in Belgium since 2012. In October 2013, she published “Le mythe de la vitamine D : Rétablir la vérité sur les hormones” (Les Éditions de l’Homme). In 2022 came “Hormones féminines et cholestérol : Alliés insoupçonnés de votre santé cardiovasculaire,” followed in 2024 by “Prévenir et traiter le cancer du sein : Le pouvoir des hormones féminines” (Les Éditions de l’Homme).
A feminist advocate, she works with a range of media to advance knowledge, dispel myths — particularly in the field of female hormones — and undo harmful, outdated prejudices.
