If you've spent years being told your gut symptoms are 'functional' with no clear path forward, the Rome V criteria published in May 2026 represent the most significant shift in gut-brain disorder diagnosis in nearly two decades.
A multinational trial found that a food-based diet (CDED) plus partial formula outperformed formula-only feeding for pediatric Crohn's disease by week 12, reaching 76% sustained remission versus 45%.
A systematic review pooling 23 studies and 2,951 stroke patients found consistent gut bacteria imbalances - fewer beneficial microbes, more harmful ones - tied to worse disability, infection risk, and recovery after stroke. The link is associative, not proven causal.
A sweeping anti-aging review zeroes in on the gut: a Mediterranean diet preserved microbial diversity in over 1,100 older adults, and young-donor fecal transplants showed early signs of reversing aging markers in mice and, more modestly, in people.
The largest gut-microbiome analysis of Parkinson's disease to date pools over 1,200 samples from six countries and finds the same bacterial pattern showing up again and again, but the signal explains less than 1% of the variation between patients and healthy people.
A new meta-analysis of 14 randomized controlled trials finds that fecal microbiota transplantation raises the odds of remission in ulcerative colitis patients by 55% compared to placebo, with oral delivery and pooled-donor strategies pulling ahead of the pack.
Across 15 countries and nearly 8,000 samples, scientists have built the most reliable microbial fingerprint of colorectal cancer ever assembled. And eating more fiber measurably shifts it in the right direction.
Scientists now know that a single NOD2 mutation can raise Crohn's disease risk by nearly fourfold, and carrying two copies pushes that risk up to 27 times higher. The genetics of inflammatory bowel disease are finally giving researchers clear molecular targets.
