by GMFH Editing Team

2025 has been a productive year in gut microbiome research, spanning metabolic health, neurogastroenterology, immune modulation, and precision nutrition. In this ‘Year in Review’ article, the GMFH editing team describes their pick of the top GMFH-covered advances in 2025, outlining their impact in the clinical setting and implications for current and future research.

The 6th biennial meeting of the European Society of Neurogastroenterology and Motility, held at Queen Mary University of London, UK, from 4-6 September 2025, covered basic, translational, and clinical research in neurogastroenterology, including dietary therapies and ‘biotics’ for the management of gastrointestinal disorders. Find out more about the main takeaways from the conference.

Digestive Disease Week 2025 featured recent basic, translational, and clinical research into the microbiome. Find out more about the main takeaways relevant for your clinical practice selected by GMFH editors.

Prebiotics have been widely researched in the context of gastrointestinal conditions and might hold potential to influence cognition outcomes by modulating the microbiota-gut-brain axis. A new randomised controlled trial in individuals aged over 60s showed that a prebiotic blend (inulin and fructo-oligosaccharides) is well tolerated and may improve cognition compared with a placebo.

After two decades of scientific exploration, the human microbiome has emerged as a critical determinant of health and disease. Fueled by multi-omics technologies and machine learning, the field has advanced from correlation-based observations to establishing causal relationships. This article presents recent and compelling examples of microbiome-based treatments that are ripe for clinical adoption and discusses challenges and opportunities facing the field based on expert interviews conducted by the GMFH team.

The 13th Gut Microbiota for Health World Summit took place 15-16 March 2025 in Washington, D.C., and it focused on advances in microbiome research to diagnose, prevent, and manage gastrointestinal and extra-intestinal conditions. Find out more about the most valuable takeaways from the event.
