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.

Can you Treat a Food Allergy by Altering the Gut Microbiome?

There is a relationship between gut microbiome and allergy which may allow some children to outgrow their food allergy.

Routine liver cancer screening extends lives for patients with alcohol-associated cirrhosis

A new study led by investigators from Mass General Brigham found routine liver cancer screening to be cost-effective and life-extending for individuals with alcohol-associated cirrhosis, even when their annual risk of developing liver cancer is less than half the risk level guiding current screening recommendations.

Vaginal estrogen use may be associated with perioperative hip fracture complications

Postmenopausal women are at greater risk for multiple health issues, such as hip fractures and urinary tract infections (UTIs), due to estrogen loss.

Antibody patterns may predict inflammatory bowel disease years before diagnosis

A large-scale study, presented today at UEG Week 2026, has identified distinct antibody patterns up to 10 years before the diagnosis of inflammatory bowel disease (IBD), potentially opening new avenues for earlier risk detection and providing insights into future disease course.

Antibiotic exposure during childhood linked to higher risk of IBS in young adults

Antibiotic use from childhood through early adulthood was associated with higher odds of irritable bowel syndrome (IBS) at age 24, with the odds increasing as the number of antibiotic prescriptions rose, according to a new study presented today at UEG Week 2026.

Your age may not tell the whole story about your health, but your blood could

Researchers analyzed plasma metabolites from 18,476 individuals aged 1 to 96 years and developed two metabolomic aging measures to assess biological aging, chronic disease, and mortality risk. Accelerated metabolomic aging was associated with greater risks of chronic disease and death, while a separate mortality-linked measure provided additional information about health status and disease burden beyond conventional clinical assessments.

E. coli eavesdrops on neighboring bacteria to stabilize gut diversity

The stability of the human gut microbiome relies on interactions between different bacterial species. However, the specific molecular mechanisms of these interactions, particularly among non-dominant species, remain largely unexplored.

Scientists studied diet and lung cancer in 95,612 adults. One eating pattern stood out

A prospective study of 95,612 U.S. adults found that those with the highest sulfur microbial diet scores had a 23% higher adjusted lung cancer incidence hazard and a 19% higher lung cancer-related mortality hazard than those with the lowest scores. However, the associations weakened after accounting for overall dietary quality and competing causes of death, and the findings do not establish a causal relationship.

Diet drinks showed no clear weight-loss edge over water after two years

In a two-year randomized trial combining assisted weight management with an unassisted follow-up year, completers maintained average weight losses of 4.8 kg with diet drinks and 3.7 kg with water. Researchers found no significant difference between groups, but fewer than half of the 493 participants completed follow-up.

Lynch syndrome patients rarely use aspirin for cancer prevention

According to international studies, taking Acetylsalicylic acid daily can protect people with Lynch syndrome from developing colorectal cancer - even at low doses. Researchers from the University Hospital Bonn (UKB), the University of Bonn, and the Center for Integrated Oncology (CIO) Bonn, in collaboration with the self-help organization SemiColon, have now found that these scientific findings have so far been insufficiently incorporated into clinical practice.
