Menopause is often referred to as "the change" and remains a complex and sensitive topic for many. Despite being historically under-discussed, it's crucial to address because of its profound impact on musculoskeletal health. Women are two to three times more likely than men to develop osteoarthritis, particularly around menopause. Changes in hormones, such as declining estrogen, can affect cartilage, bone density, inflammation, muscle health, and body weight - factors closely linked to joint pain and osteoarthritis symptoms. In this episode of the Joint Action Podcast, Dr. Ginny Mansberg, a GP and women's health expert, joins Prof. David Hunter to explore the intricate relationship between menopause and osteoarthritis. They discuss the physical and emotional challenges women face, including sleep disruption, weight gain, joint pain, and mental health issues like anxiety and depression. Dr. Mansberg shares valuable insights into how hormone replacement therapy (HRT) and lifestyle strategies, including exercise, can help manage symptoms and improve long-term health outcomes. Whether you're navigating menopause or supporting someone who is, this episode offers a compassionate, evidence-informed perspective on understanding and managing the journey.
