The goal of this issue of Gastroenterology Clinics is to present GI diseases which affect women uniquely, such as pelvic floor problems and pregnancy related disorders, or which require a more considered approach such as functional bowel disease or autoimmune processes. It will also address the position of women and female gastroenterologists in the health system as a whole. This issue is published at an exciting, transitional time in the future of gastroenterology, as we adjust approaches for the assessment of disease in a large portion of our patient population, and as we address the challenges in practicing medicine based on the uniqueness of specific populations.

With collaboration of Consulting Editor, Dr. Alan Buchman, Guest Editors Drs. Gerard Mullen and Berkeley Limketkai have created a practical and current issue covering the breadth of topics in nutrition and gastrointestinal disease.

In the last three decades, the prevalence of obesity has doubled with over 600 million obese adults worldwide. The gastrointestinal complications of obesity are well publicized; however, the role of the gastrointestinal tract in the development and treatment of obesity is often understated. From the pathophysiologic role of gut hormones and the microbiota, to the purposeful, anatomic derangement of the gastrointestinal tract that is utilized as a treatment for obesity, it is imperative that gastroenterologists understand the full scope of obesity in relation to the gastrointestinal system. Studies suggest that in the U.S. obesity is underrecognized and undertreated by health care providers. Given its complex sociology, pathophysiology, and treatment, obesity, like many other diseases, requires a multidisciplinary approach. Therefore, gastroenterologists must be equipped with the relevant knowledge of obesity that will empower them to properly manage their patients.

In this issue of Gastroenterology Clinics, guest editor Dr. John A. Martin brings his considerable expertise to the topic of Advances in Endoscopy. Endoscopy has forever changed the fundamental nature of the clinical gastroenterologist's practice, from one that was originally predominantly clinic-based, to one that, today, is largely driven by endoscopy. In this issue, top experts explore and celebrate the now numerous facets of diagnostic and therapeutic endoscopy that markedly benefit patients today and continually advance to empower the gastrointestinal endoscopist more and more, year by year. - Contains 14 relevant, practice-oriented topics including pediatric endoscopy; ERCP: biliary and pancreatic endoscopy; endoscopic ultrasound; advanced esophageal endoscopy; artificial intelligence in endoscopy; and more. - Provides in-depth clinical reviews on endoscopy, offering actionable insights for clinical practice. - Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews.
