Gastrointestinal Health

This hub offers a comprehensive resource on gastrointestinal health, digestive diseases, and the human microbiome, drawing together authoritative articles on basic science, clinical management, and emerging research. The collection addresses the pathophysiology, diagnosis, and treatment of major gastrointestinal disorders, including irritable bowel syndrome, celiac disease, inflammatory bowel disease, and gastroesophageal reflux, while also exploring surgical, dietary, and pharmacological interventions. Special emphasis is given to the role of the gut microbiome in health and disease, including its influence on immunity, metabolism, neurological function, and response to therapy. Readers will also find up-to-date insights into microbiome-related interventions, such as fecal microbiota transplantation, as well as practical guidance for dietary management and prevention. This hub serves as a trusted reference for clinicians, researchers, and individuals seeking an evidence-based understanding of digestive and microbiome science.
