Spending time speaking with Professor Jerilynn Prior is a humbling experience that always gives me new insight - and this week’s podcast episode does not disappoint. Jerilynn is a professor of endocrinology and metabolism from the University of British Columbia in Vancouver, and she has dedicated her career to the study of menstrual cycles and the effects of cycles in their changing estrogen and progesterone hormone levels on women's health. In 2002, she founded the Center for Menstrual Cycle and Ovulation Research Center, better known as CeMCOR. And this houses a wealth of information. Jerilynn is also the director of the British Columbia Center of of the Osteoporosis study, which was studying osteoporosis fractures and bone mineral density, and has followed over 9,000 women and men across the country for 19 years plus a thousand younger women. In this episode, we focus on discussing osteoporosis. She shares with us her ABCs of osteoporosis prevention and treatment. We also, of course, talk about HRT and why she and I both believe that this term should no longer be used. We also delve into the misnomers around using DEXA scans to diagnose osteoporosis.
