This book presents the surgical therapy of obesity and metabolic diseases in a practice-oriented and detailed way. The specific surgical procedures with their indications, performance and risks are described precisely in words and pictures. Special emphasis is placed on the choice of the appropriate surgical procedure for the individual patient. In addition to the mechanisms of action, interdisciplinary preoperative evaluation of the patient and postoperative aftercare are explained. Furthermore, surgical, internal and psychosomatic complications and complication management are described. Information on obesity center organization and alternative bariatric therapies complete the volume.

This book is a translation of the original German 1^st edition Adipositas- und metabolische Chirurgie by Jürgen Ordemann & Ulf Elbelt, published by Springer-Verlag GmbH Germany, part of Springer Nature in 2017. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
