Celiac disease (CD) is defined as a permanent sensitivity to the gluten in wheat and related proteins found in barley and rye. It affects 0.5-1% of the general population world-wide. Currently the only available treatment is lifelong adherence to the gluten-free diet (GFD). This book discusses the lifestyle and financial implications that GFD has on patients as well as the nutritional diets that must be followed in both children and adults. The clinical presentations of CD are categorised into three main groups: Malabsorption, autoimmunity and gut dysmotility. These three main groups are discussed as well as recently published work on celiac disease and the pregnancy outcome of patients with CD. Finally, techniques such as MR-enterography that are used to identify CD are addressed in this book as well.
