"Dyspepsia in Clinical Practice" is a comprehensive professional book that addresses the complex topic of dyspepsia. Despite years of research on this subject, there is no uniform definition or standardized guidelines worldwide, highlighting the need for a clear and practical approach. This book provides a summary of current guidelines and presents a unified, practical definition of dyspepsia. It includes a diagnostic algorithm that focuses on upper gastrointestinal endoscopy and follows a rational initial therapeutic approach based on epidemiology, pathophysiology, clinical presentation, and response to previous therapies. The information is presented from the perspective of practitioners and also considers dyspepsia in children and the elderly, a topic often overlooked in the literature. The provided guidelines are easily implementable in clinical practice and contribute to cost reduction as well as increased patient safety. This book is a valuable resource for gastroenterologists, internists, family physicians, pediatricians, and healthcare professionals in training.
