The Age of Diagnosis: How Our Obsession with Medical Labels Is Making Us Sicker

Suzanne O'Sullivan examines the rapid expansion of psychiatric and physical health categories that define contemporary life. She argues that the drive to categorize every human discomfort as a clinical pathology creates a feedback loop where medical language dictates how individuals perceive their own bodies and minds. Through clinical case studies and historical analysis, the text documents the shift from treating visible pathology to managing identity-based syndromes. O'Sullivan details how diagnostic checklists often overlook environmental and social stressors, resulting in medical interventions that institutionalize suffering rather than resolving it.

This book is intended for medical practitioners, sociologists, and patients navigating the complexities of chronic illness. Readers will understand the psychological mechanisms that cause people to adopt symptoms based on cultural expectations and medical labeling. The text provides a framework for distinguishing between biological disease and the psychosomatic responses triggered by the modern healthcare system. Those finishing the book will possess a clearer perspective on the limitations of modern diagnostics and the potential risks of seeking a medical name for every form of human distress.
