What are the treatment options for Crohn's disease?

Crohn's disease causes inflammation in parts of the digestive tract, and symptoms can change between active disease and quieter periods. The plan depends on which areas are affected, the intensity of inflammation, previous treatment, nutrition, and complications such as narrowing or an abscess. Medicines may calm inflammation or modify the immune response. A [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) can coordinate assessment and referral when specialist care is needed.

Take prescribed medicine consistently and do not stop it because symptoms improve without first discussing the change. Keep a record of bowel symptoms, abdominal pain, weight changes, food triggers, and medicine effects. A [Blood Test](/treatments/diagnostics-and-screening/blood-test/) may help clinicians check inflammation, anaemia, or treatment safety. During a flare, ask for an individual plan rather than starting medicines intended for someone else. A dietitian may help if eating is difficult, weight is falling, or deficiencies are suspected.

Seek urgent assessment for severe or persistent abdominal pain, repeated vomiting, a swollen abdomen, inability to pass stool or gas, heavy rectal bleeding, high fever, faintness, or signs of dehydration. Contact your care team promptly if diarrhoea or pain is rapidly worsening, you are losing weight, or prescribed treatment is causing concerning effects.

Ask what your treatment is intended to achieve, how improvement will be monitored, which symptoms suggest a flare, and whether you need nutritional or specialist support.
