The lifelong care required for bariatric surgery patients often presents colleagues in the office with the situation of having to identify surgical and nutritive complications related to the previous surgery. This often requires very specialized knowledge not only of the surgical procedures themselves, but especially of the metabolic changes that follow surgery. 

Based on many years of experience in the leading surgical obesity centers in Germany, the editors have compiled this book. It offers practical guidance for the follow-up care of obesity patients who have undergone surgery. With practical relevance, the book supports general practitioners and internists in their competence to recognize and treat postoperative changes and complications.
