You've heard about placebo's? Well what about nocebos?
The Age of Diagnosis: How Our Obsession with Medical Labels Is Making Us Sicker

Briefly, what is this book about?
The idea that putting labels on something is not a free lunch—like everything else there are tradeoffs. Rather than framing numerous illnesses as being psychosomatic, O'Sullivan seems more to be suggesting that humans are very suggestible. (I get the meta-ness of the statement.) As such, once you generate a label it has a tendency to warp identities, and make people seek out confirming evidence. This all creates a sort of nocebo effect which may increase the severity of whatever symptoms they're experiencing.
To put it more succinctly, labels have power and we should be circumspect about applying them.
What's the author's angle?
O'Sullivan is a neurologist who noticed that lots of patients have "normal" tests, but are also indisputably suffering. As someone more focused on the brain than other parts of the body, she has long contended that expectations, culture, current fads, etc. play a much bigger role than most doctors want to admit. It's not all about biology, psychology also has a role. Previous books include It's All in Your Head: True Stories of Imaginary Illness and The Sleeping Beauties: And Other Stories of Mystery Illness.
Who should read this book?
Anyone interested in a broader discussion of how the world outside of medicine interacts with the world of medicine. How the epistemic crisis, culture, disease advocacy groups, bureaucracy, and patient longing all affect the act of putting a label on a cluster of symptoms.
What does the book have to say about the future?
