Medicine for Dummies is a continuing series designed to encourage readers to think differently about health, illness, diagnosis, and treatment. Drawing on Dr. Smith's 55+ years of clinical experience and many hundreds of individual case histories, each installment looks beyond symptoms, diagnostic labels, and one-size-fits-all treatments to explore possible underlying causes of illness. The goal is to encourage readers to ask questions, consider alternatives, do their own research, and make informed decisions about their health.
