  • About your appointment

    If you have been given an appointment with a dietitian, you will be sent a letter with information on what to expect. You will see a named, state-registered dietitian at your appointment.

    We are a training site for dietitians. In some clinics you may be seen by a trainee dietitian who is under direct supervision of a state-registered dietitian. Trainees identify themselves at the start of appointments.

    The length of time you will spend with the dietitian will depend on the reasons that you have been referred.

    If you need a follow-up appointment, this will usually be arranged before you leave the hospital.
