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.

New strategy targets Porphyromonas gingivalis without harming healthy microbes

For years, treating gum disease has meant scraping away plaque, cutting out damaged tissue or turning to antibiotics that kill bacteria indiscriminately.

Gut bacteria may explain differences in peanut allergy reactions

One of the big mysteries in food allergy is why two people with similar levels of peanut specific antibodies can react so differently. It turns out the answer may be in the mouth and gut's bacteria.

New collaboration explores familial inflammatory bowel disease in Saudi Arabia

Mount Sinai and King Saud University Medical City in Riyadh, Saudi Arabia, today announced a three-year collaboration aimed at better understanding why inflammatory bowel disease (IBD) runs in some Saudi families, and how that knowledge can lead to risk ascertainment, earlier diagnosis and more personalized treatment options.

Study links gut microbiome health directly to ovarian aging processes

A new study details how fecal transplants from older female mice significantly improve ovarian function and fertility in young mice. The surprising results reveal a direct link between the microbiome (the collection of all bacteria and other microbes present) of the gut and ovarian health and function.

Experts identify safest and most effective diets for IBS management

This review in Nutrients evaluates the scientific evidence, clinical effectiveness, and safety of major dietary strategies for irritable bowel syndrome, including traditional advice, low-FODMAP, gluten-free, Mediterranean, and starch- and sucrose-reduced diets. It concludes that while the low-FODMAP diet has the strongest short-term evidence, no single approach fits all patients, and dietitian-led personalization is essential.

High-dose curcumin fails to produce lasting gut microbiome changes in IBD patients

In an open-label study of 29 men, including patients with ulcerative colitis and Crohn’s disease in remission, 6 g per day of curcumin for eight weeks led to modest, transient shifts in gut microbiota composition without sustained restructuring. Despite achieving high fecal concentrations and minimal systemic bioavailability, curcumin did not produce durable microbiome changes, and disease activity scores remained stable.
