This book is a translation of the original German edition „Adipositas- und metabolische
Chirurgie“ by Ordemann, Jürgen, published by Springer-Verlag GmbH, DE in 2017. The
translation was done with the help of articial intelligence (machine translation by the
service DeepL.com). A subsequent human revision was done primarily in terms of con-
tent, so that the book will read stylistically differently from a conventional translation.
Springer Nature works continuously to further the development of tools for the produc-
tion of books and on the related technologies to support the authors.

Preface

Isolated cases of pronounced obesity have been found since the early
stages of human history. However, obesity has emerged to be a signicant
health problem over the last 100 years—with unforeseeable consequences
for the development of mankind. Obesity is a chronic disease that can
shorten life span and lead to various complications such as metabolic syn-
drome, sleep-related breathing disorders, neoplasm and reduced fertility.
The effect of conservative treatment is usually low and of limited dura-
tion. Conservative therapies such as nutritional therapy, physical exercise
therapy and behavioural therapy are associated with major challenges for
the person concerned. In the case of drug therapy, undesirable effects can
also occur. To date, the underlying pathophysiology and genetic predispo-
sition of the affected persons cannot be adequately addressed by conserva-
tive therapies and the dramatic environmental changes leading to obesity
are also difcult to inuence at an individual level.
In contrast, surgical measures can signicantly improve the course of
obesity. Mortality and morbidity are signicantly reduced compared to
conservative therapy. In the meantime, obesity surgery and metabolic sur-
gery have become established forms of therapy for obesity and its compli-
cations. Due to insufcient information, however, patients who are affected
and their therapists still have considerable concern. In addition, health
insurance companies also have strong reservations. In comparison to other
countries, obesity surgery is still very rarely performed in Germany.
Our practice-oriented textbook is mainly for surgeons who would
like to familiarize themselves with the indications, surgical procedures,
metabolic interventions, risks and aftercare of obesity surgery. An inter-
disciplinary approach in the treatment of people with obesity and asso-
ciated secondary diseases is of particular importance. For this reason,
nutritional medicine, internal medicine and psychosomatic issues are
featured in this textbook in detail. Our textbook is also intended to help
guide nutritional physicians, internists, general practitioners and mem-
bers of the professional groups involved in the treatment of obesity. We
intend to provide practical knowledge for the care of obese patients and
to improve the understanding of prevention, complications and after-
care of bariatric surgery for these different professional groups.
Many people contributed their expertise to the development of this
textbook. First, our thanks go to the authors of the different chapters.
We would also like to thank Dr. Fritz Kraemer and the team at Springer.
We would like to particularly thank our editor Heidrun Schoeler for her
cooperation and commitment.
We hope that this textbook will be helpful to professionals who are
involved in the treatment of obesity and that it will encourage them to
provide an interdisciplinary approach to their patients.
