PMOS reveals the long road to truly personalized health

Victoria Song argues that renaming PCOS to PMOS reflects a broader hormonal and metabolic condition, and that personalized health tech is not yet capable of reliably addressing chronic illnesses. While wearables and AI promise tailored guidance, PMOS manifests differently across individuals, interacts with insulin resistance and medications, and is influenced by factors like hormonal contraception, making universal personalization elusive. Despite industry optimism, real-world personalization still requires significant self-tracking, medical input, and trial-and-error, highlighting a gap between hype and what current science and healthcare systems can safely deliver.
