Dr John Sinn 

MBBS (Syd), M Med (CEpi) DCH, Dip Paed, FRACP

Paediatric Allergist and Neonatologist


Dr John Sinn is a paediatric allergist for infants and children at The Paediatric Centre. Dr Sinn's  interest is to decrease food allergy sensitivity via step ladder approach. We use  allergen modification techniques  to lower the allergenicity of allergens like cow milk, egg, nuts and fruits. Gradually the child will go up the ladder to the next level of allergenicity.  This develops tolerance with eventual  aim of desensitisation and able to ingest the allergen. 


Prevention and treating eczema is the first step in the management of allergies. Avoiding moisturiser with food in its ingredient is one way to stop developing new allergies.  Aeroallergens like dust mite, grasses and pollen often exacerbate eczema and we offer  immunotherapy via subcutaneous injection or sublingual route to dust mite, cat, dog,  pollen and other aeroallergens. 


Dr John Sinn is also a Consultant Neonatologist at RNSH.  He looks after intensive care babies from birth. He has written national guidelines on  probiotics and nutritional policies for infants. He is on medicine advisory board for Department of Health and on the board of Australian Neonatal formulary.  He supports breast feeding and when tongue tie cause significant feeding difficulties he is accredited to performed tongue tie ligation and has performed  hundreds  with the aim of assisting successful breast feeding. He is one of the authors of the tongue tie guide line published  by the Australian Dental Association, a national consensus statement. 


He is a full member of Australasian Society of Clinical Immunology and Allergy (ASCIA)  and has been on policy boards of RACP, ASCIA, EAACI, FSANZ, PSANZ and NHMRC. He has been an accredited consultant in the  Department of Immunology and Allergy at RPAH and RNSH.  He has extensive publications in areas of allergy prevention, food intolerances, cows milk allergy, microbiome, probiotics and prebiotics, and immunisations. He has written national policies on cow's milk intolerance and food allergy prevention strategies.  He has written more than 10 Cochrane reviews which are the major reference points for probiotics, prebiotics, allergy prevention, hydrolysed protein, iodine, soy, amino acid, ADHD and omega 3.  There are more than 3350 publications that has cited Dr Sinn's research papers. He is an international and national invited speaker, presenting regularly on nutrition, probiotics, microbiome and allergy. Internationally he has been invited to speak at government levels from countries like China, Hong Kong, India, Vietnam and Malaysia on nutrition, microbiome and allergy. He is an author on the guideline for the first 1000 days which is in every new mother's information pack in Australia and New Zealand with a distribution of >500000 booklets.
