1. Recognise your symptoms
You might have an obstruction if:
- You’re having abdominal pain or cramps.
- Your tummy is bloated or distended.
- You are feeling or being sick.
- You are constipated or not passing gas, or you might have bursts of diarrhoea.
2. Get in touch
If Monday to Friday 9am-4pm, contact the IBD helpline straight away.
Outside of these hours, call NHS 111
IBD helpline (answerphone service)
01273 664427
3. While awaiting a response
- Do not eat or drink for 3-6 hours.
- Then only drink fluids for 24 hours.
- Then gradually reintroduce easy to digest foods.
4. After speaking to your team
- Remain on a low residue diet (avoid nuts, seeds, brown cereals, fruit and vegetable skins).
- Consider drinking liquid supplements like Complan, Aymes or Modulin – this can help improve your symptoms, give you extra nutrients and reduce inflammation.
Go to hospital if:
- You are being sick persistently.
- You have severe abdominal pain.

Staying safe
Medication safety
