How can this event help me?
Polyendocrine Metabolic Ovarian Syndrome (PMOS), previously known as Polycystic Ovary Syndrome (PCOS), is a common hormonal and metabolic condition that can affect women throughout their lives. It can influence much more than reproductive health, with potential effects on hormones, metabolism, blood sugar, weight, cardiovascular health and overall wellbeing. Understanding how these different aspects of your health are connected can help you make more informed choices about your care.
In this BJC Connect event, Endocrinologist Dr Cellina Ching will explore PMOS and the ways it can affect your health at different stages of life. She’ll explain the connection between hormones and metabolic health, what to be aware of as your health changes over time, and the practical steps that can help support your wellbeing.
In this session, Cellina will be discussing:
Understanding PMOS: Learn more about the condition, how it can affect your body and the different symptoms and health considerations associated with it
PMOS and your health: Explore the connections between hormones, metabolism, reproductive health and other aspects of your wellbeing
PMOS through different stages of life: Understand how symptoms and health considerations can change from adolescence through adulthood and beyond
Hormones and metabolic health: discover how blood sugar, cholesterol, body composition and hormones can interact and influence your health
Looking after your health with PMOS: explore how movement, exercise, nutrition, sleep and other lifestyle factors can support your health over the long term
Join us on Wednesday, October 28th at 8:00 PM AEDT for this informative live online event with Endocrinologist Dr Cellina Ching. As always, we welcome your questions and discussions to make this an engaging and supportive experience for everyone.
