What Science Tells Us About Childbirth That Your Doctor Won't | Assoc Prof Yvette Miller | TEDxQUT

Miller begins by illustrating how routine pregnancy appointments can trigger a cascade of medical interventions based on imprecise guesswork about due dates and baby size, which naturally vary by up to 37 days. She reveals that one in three women labeled high-risk are not actually high-risk, yet this labeling initiates a chain reaction: induction, drug-induced labor, restricted movement, epidurals, and potentially surgical intervention. Miller criticizes the maternity guidelines that drive these practices, noting that 90% lack strong scientific evidence and 40% are based purely on opinion rather than data. She traces this problem to a fundamental shift over the past century where birth transitioned from being viewed as a normal life event to a medical condition requiring management, based on the assumption that women's bodies are unreliable and prone to failure. Miller then examines specific interventions with poor evidence: the lithotomy position (lying on back), which fights gravity and narrows the pelvis despite being convenient for medical staff; episiotomy (cutting the perineum), which was promised to prevent tearing but actually increases severe tearing, pain, and pelvic floor damage; and continuous fetal monitoring, which doesn't improve outcomes for babies but increases surgical birth risk. She notes that less than 15% of pregnancies benefit from medical intervention, yet more than 70% receive it, creating a significant gap where intervention causes more harm than good. Miller emphasizes that pregnant women receive inadequate information about their options, with less than one in 10 hearing about all available choices. She concludes by proposing three empowering questions women should ask: Is there a real problem or just in case? What could I do instead? What if I said no right now?
