Your child's appointment with the gastroenterology and nutrition service

How do I get an appointment?

Your child must be referred to our service by their GP. For more information about getting or making a referral see our referrals page.

Changing or cancelling your appointment

If you need to change or cancel your child's appointment for any reason, please call the appointments office on 020 7188 4000 or email

Please tell us as soon as possible so we can offer the appointment to another patient.

Before your appointment

If your child has diarrhoea or blood in their poo, please bring a sample of their poo to the clinic.

It is also helpful to bring your child's red book (personal child health record) to the appointment, along with a list of any medicines they are taking.

During your appointment

You and your child will see a specialist gastroenterology doctor (either a consultant or a registrar) who will discuss your child's condition and symptoms with you.

Your child's appointment will usually last about 20 minutes. However, the length of the appointment can vary depending on your child's condition.

As we're a teaching hospital, students and visitors may be observing the team. We'll always ask your permission for them to observe your appointment.

After your appointment

At the end of the appointment, you and your child will be given a clinic outcome form which provides information about our diagnosis.

Your child will then either be given another appointment, referred for further tests, referred for admission to hospital or discharged back to your referring doctor.

We'll write to the referring doctor to explain what happened at the appointment and what will happen next. We'll send a copy of this letter to you, your GP and any other clinicians or healthcare professionals involved in your child's care. 

The letter will have a contact number if you have any questions.
