This is the first complete textbook to examine the myriad complications of rheumatic syndromes in the gastrointestinal tract. Each disease is summarized for a broad medical audience, with focus on the consequences of the disorder throughout the gut. The reader will formulate an understanding of the clinical, pharmacological, and nutritional aspects of the interface of these two specialties with expert contributors from a range of academic centers. Rheumatologists and gastroenterologists will be able to recognize, evaluate, and treat gastrointestinal symptoms of autoimmune diseases and collaborate in improving the experience and outcomes of these complex patients.
