Does filling the colon with water make colonoscopy easier? What a 2026 systematic review and meta-analysis of 30 trials actually found
Water infusion — filling the colon with warm water instead of air or CO2 — has been studied as a gentler way to do a colonoscopy. A 2026 systematic review and meta-analysis pooled 30 randomized trials: it found no difference in adenoma detection, reaching the cecum, or procedure time, but fewer people needed on-demand sedation (risk ratio 0.61) or abdominal pressing (risk ratio 0.65). A comfort finding, not a detection upgrade — and whether it's offered depends on your endoscopy unit.

Ear, nose and throat signs in IBD: what a 2026 systematic review actually documents
Joints, eyes and skin are the extraintestinal manifestations of inflammatory bowel disease that most people have heard of. A 2026 systematic review pulls together the ear, nose and throat side of the picture — uncommon, mostly documented in small case series, but consistent enough that the authors think clinicians should be looking.

Microbiota and FMT in IBD: what a 2026 systematic review actually surveys
Patients with inflammatory bowel disease hear a lot about the gut microbiome and about fecal microbiota transplantation — sometimes presented as a quiet cure, sometimes dismissed as fringe. A 2026 systematic review pulls the current literature together and draws a more honest picture: established for one infection, still investigational for IBD itself.

Does IBD play a role in cognitive decline? What a 2026 systematic review of 66 studies actually says
Brain fog and forgetfulness are something the IBD community has talked about for years. A new 2026 systematic review pools 66 studies and finds the link is real enough to take seriously — and small enough, still, that the careful word in every sentence is 'associated'.

When 'temporary' isn't: what a 2026 meta-analysis says about loop ileostomies after rectal cancer surgery
A 2026 systematic review and meta-analysis pooled 19 studies and nearly 10,000 patients to ask a simple, uncomfortable question — when a diverting loop ileostomy is planned as temporary after rectal cancer surgery, how often does it actually become permanent?

When fatigue isn't 'just being tired': what a 2026 review tells us about anaemia risk in IBD
Anaemia is one of the most common companions of inflammatory bowel disease. A 2026 systematic review and meta-analysis pooled the existing studies to ask which patients face the highest risk — not to predict the future, but to map what's worth looking for.

Does inflammation track with low mood in IBD? What a 2026 meta-analysis of CRP and depression actually found
Higher inflammation, lower mood — it's an intuitive link, and a 2026 meta-analysis in inflammatory bowel disease finds the two are associated. But the word 'associated' is doing a lot of quiet work in that sentence, and it matters.

When it might not be the flare: a 2026 expert update on C. difficile infection in IBD
A C. difficile gut infection can look almost exactly like an IBD flare — same diarrhoea, same urgency. A 2026 American Gastroenterological Association practice update exists precisely because telling them apart changes what should happen next.
