What should you know about wheatgrass ulcerative colitis?

Ulcerative colitis is an inflammatory condition affecting the lining of the large bowel. It can present with diarrhoea, urgency, rectal bleeding, abdominal pain and tiredness. Wheatgrass does not remove the underlying inflammation, so stopping prescribed medicine to use it can allow symptoms to worsen. Products may also vary in preparation and can add nausea, bloating or loose stools, making it harder to judge whether the condition is active.

Read more about [Ulcerative Colitis](/conditions/ulcerative-colitis/) and tell your clinician about every supplement, powder or juice you use.

Continue treatment as prescribed unless the clinician managing your bowel condition changes it. If you want to try wheatgrass, discuss the product, ingredients and dose first, especially during a flare or if you take medicines that affect immunity. Keep a record of bowel frequency, blood, pain, fever, appetite and any change after the product. A [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) can help decide whether symptoms need examination or tests.

Contact your care team promptly for increasing diarrhoea, new or heavier rectal bleeding, persistent abdominal pain, fever, dehydration or marked weakness. Seek urgent help for severe abdominal swelling or pain, fainting, confusion, or inability to keep fluids down. Screening decisions are separate from supplement use; ask your clinician about [Colorectal Cancer Screening](/treatments/diagnostics-and-screening/colorectal-cancer-screening/) when relevant to your history.

Ask whether wheatgrass could interact with your medicines, whether your current symptoms suggest a flare, and what signs should trigger same-day advice. Ask for a clear plan before changing any prescribed treatment.
