Amenorrhea, Energy Deficiency & the Female Athlete
About this episode
The episode discusses amenorrhea and its implications for female athletes, focusing on energy deficiency and hormonal health.
We dive into the often-overlooked topic of amenorrhea: the absence of menstruation. Biomechanist Katy Bowman and biologist Dr. Jeannette Loram unpack the science with a focus on Functional Hypothalamic Amenorrhea (FHA) linked to energy deficiency in athletes. They explore how intense training and and sport pressures around leanness or weight can disrupt regular hormonal signals, affecting long-term bone density, cardiovascular health, and performance. They also discuss the original concept of the Female Athlete Triad (low energy availability, menstrual dysfunction, and low bone mineral density) and its evolution into RED-S (Relative Energy Deficiency in Sport), a more holistic model encompassing many aspects of health and wellbeing. The conversation expands into evolutionary perspectives, comparing Western menstrual experiences—from menarche to menopause—with those of hunter-gatherer populations like the Hadza, and questioning what “normal” really means. Ultimately, this episode reframes intense athletics as a nuanced practice that must be supported by adequate nutrition and recovery.
