Can enteral nutrition therapy help achieve remission in patients with ulcerative colitis?
Enteral nutrition (EN) therapy involves using liquid formula diets as a primary or supplemental source of nutrition. For ulcerative colitis (UC), the question is whether EN can help calm inflammation and lead to remission. Current evidence suggests EN may be beneficial, especially in acute severe UC, but it is not a standard first-line therapy for UC as it is for Crohn's disease. Studies show clinical remission rates around 60% in some UC patients, and EN may help modulate the gut microbiome and reduce inflammation.
What the research says
A retrospective study of 350 Chinese UC patients found that enteral nutrition therapy was associated with clinical remission in 60% of patients over 6 weeks, defined as a Mayo score ≤ 2 with no individual subscore > 1 5. This suggests EN can be effective for some UC patients, though the study did not compare EN to other treatments. A 2026 review on acute severe UC (ASUC) notes that exclusive enteral nutrition plays an important role in comprehensive management by modulating the gut microbiome, alongside other therapies 10. Another study in pediatric IBD patients found that both exclusive enteral nutrition and corticosteroids changed the gut microbiota, and patients who achieved remission had distinct microbial profiles, though this study included mostly Crohn's disease patients 11. A network meta-analysis of dietary supplements for UC did not specifically evaluate EN formulas, but it found that probiotics and certain supplements like selenium and flaxseed extract improved clinical scores 7. Overall, the evidence for EN in UC is less robust than for Crohn's disease, but it may be a useful adjunctive therapy, especially in hospitalized patients with acute severe disease.
What to ask your doctor
- Could enteral nutrition therapy be helpful for my ulcerative colitis, especially if I have active disease or am hospitalized?
- What type of enteral nutrition formula (elemental, semi-elemental, or polymeric) would be most appropriate for my condition?
- How long would I need to use enteral nutrition to see potential benefits, and what are the side effects?
- Is exclusive enteral nutrition recommended for acute severe UC, or is it mainly used for Crohn's disease?
- Can enteral nutrition be combined with my current medications, or is it used as a replacement?
