 When to visit us

Your GP or non-GP specialist is always your first step in seeking treatment for any condition. You will be referred to our service if your treating doctor feels that your treatment requires the input of Endocrine Surgery. Once we receive the referral it will be reviewed by a doctor and you will be notified of the outcome and next steps. Please allow at least 4 weeks for this process to be undertaken. We see patients either face-to-face or via telehealth – our team will let you know what the best option is for you. 


Please note that phone calls from the hospital will appear as a blocked number. 


If you have a scheduled appointment you will receive a reminder text message. 


Please allow a full morning or afternoon for your appointment. Some patients require a longer review and delays can occur.
