Dr Nitin Gupta

I have been working as a Paediatric Gastroenterologist at the Sydney Children’s Hospital Network (Randwick) since 2011.  At the Syndey Children’s Hospital, I look after infants and children with complex medical and nutritional issues in diseases of the gastrointestinal tract and liver.  My clinical interests include general gastroenterology, Inflammatory Bowel Disease (IBD), Total Parenteral Nutrition (TPN) as well as Cystic Fibrosis.

During my training years, I took opportunities to move between various gastroenterology departments in tertiary hospitals in South Australia, New South Wales and Queensland.  Each of these centres have specialized clinical and academic interests that allowed me a thorough education into the broader gastroenterological disorders of Motility (Adelaide), Inflammatory Bowel Diseases (Sydney Children’s Hospital) and Liver diseases (Brisbane).

My family moved from India to Australia when I was five years of age.  I grew up in regional South Australia before moving to Adelaide for my medical degree and the start of my paediatric training.

My current positions include:

• Staff Specialist, Sydney Children’s Hospital Network (Randwick)
