Coronavirus: nutrition and dietetics service update

Due to increased demand on the hospital due to the coronavirus (COVID-19) pandemic we are having to make significant changes to our services which may require cancellation of appointments.


We are attempting to contact all patients with a future scheduled appointment. In some cases we are changing appointments to a telephone consultation or a video appointment. Some appointments may be cancelled without a future date being arranged. If we cancel your appointment you will remain on our waiting list and we will contact you in due course. Some patients may be discharged back to their GP and we will write to you if this is the case.

If you have not heard from us within three days of your scheduled adult or paediatric appointment please email

If you are unable to use email or your query is urgent, please call 020 7188 4128. Our phone lines are very busy and there may be a wait for your call to be answered. If the line is engaged please call back at a later time. You may get a quicker answer if you email rather than call.

Existing patients 

If you are an existing patient who has previously been seen in our service and need advice from the clinical team please see below for the appropriate option:

Email for:

  • any queries regarding your appointment or the contact details we have for you
  • any clinical advice.

Telephone 020 7188 4128:

  • for any queries regarding your appointment or the contact details we have for you
  • any clinical advice.

South-east London healthy weight programme

We have resumed initial assessments for the service. All consultations and programme sessions will take place by telephone or a video consultation. Please visit the healthy weight programme page for more information. 


Advice and guidance

We are doing everything we can to support GPs and your patients during the coronavirus (COVID-19) pandemic. If you need advice from our clinical team please use the current advice and guidance channels including e-RS advice and guidance for written communication, or email

Prior any referral, we strongly advise that GPs seek advice and guidance via e-RS. Please note that all of our services available on e-RS are set up for advice requests.

This will enable the clinical team to review your request and provide an interim treatment plan for ongoing management of a patient. They can also adviseprovide clarification regarding a patients test results.

The GP can attach documents to the e-RS advice request, which may include diagnostic results, scanned images (eg ECGs). Providers can also respond with attachments.


If you feel that a referral is absolutely necessary, please refer via e-RS and use the 'defer to provider' functionality for urgent referrals. Please attach the referral letter at the point of referral or within 24 hours.  

The Trust will vet the referral and either book into a virtual appointment or add the patient to the waiting list if they need a face to face appointment. In some cases the referral may be returned (rejected) back to you with advice.

Please do not 'defer to provider' routine referrals. Send the appointment request to the patient so they can do this when they are ready to book.

Please consider this before making any referral as our capacity to see new patients is very limited.

For any training issues or technical assistance with e-RS/smartcards, please contact your local commissioning support unit (CSU) or registration authority helpdesk.

About us

Dietitians are qualified health professionals that help promote nutritional wellbeing and diagnose and treat nutrition related problems. Your dietitian will provide you with practical and safe advice that is based on current scientific evidence.

The dietitians at Guy's and St Thomas' NHS Foundation Trust and Evelina London Children's Hospital work together to treat multiple clinical conditions. They work in all areas of the hospital and in the community providing nutritional care to patients and staff. The head of service is Rachael Strauss.

Our department supports, clinical work, education and research. We have close links with a number of universities and have joint appointments with King's College London (KCL).

We also train under and postgraduate dietetic students across the year from KCL.

We are pioneers for group education and offer a number of patient groups.

  • Patient groups

    • Bariatric support group
    • Breast cancer: moving forward – for breast cancer patients post treatment run by the Breast Cancer Care charity, patients can book themselves on via the Breast Cancer care website

    • Cardiac rehab – one-off session
    • Gastroenterology: Coeliac disease – group sessions for patients with coeliac disease. The groups provide an opportunity to meet other people with coeliac disease to share information and learn from each other
