Professional statement

Dr Michael Hii is an esteemed consultant paediatric gastroenterologist with extensive expertise in his field. He currently serves as senior gastroenterologist at the Royal Alexandra Children's Hospital, a leading tertiary paediatric gastroenterology centre that accepts referrals from across Sussex and Surrey.


Before this role, he held a locum consultant paediatric gastroenterologist position at Chelsea and Westminster Hospital. Dr Hii notably earned an MSc in paediatrics from Birmingham University in 2003, further solidifying his advanced knowledge in the field. A graduate of the prestigious Royal College of Surgeons in Ireland in 1998, Dr Hii achieved MRCPCH membership in 2001.


He honed his skills in general paediatrics and gastroenterology at some of London's most reputable hospitals, including Great Ormond Street Hospital, Royal Free Hospital, and Chelsea and Westminster Hospital. Additionally, he dedicated two years as a Hepatology Clinical Fellow post-CCT at the Supraregional Liver Centre at King’s College Hospital, gaining invaluable experience in paediatric liver conditions.


Dr Hii’s expertise spans both general paediatrics and gastroenterology, enabling him to manage a wide range of conditions. He established the Paediatric Gut Investigation Clinic (PGIC) in 2017 in collaboration with Paediatric Diagnostics. This unique clinic offers a comprehensive “one stop clinic” offering various gut investigative tools such as hydrogen breath test, hydrogen/methane breath test, 24 hour PH study, skin prick testing, video capsule endoscopy and ultrasound. The clinic is supported by a multidisciplinary team, including nurses, paediatric dietician, and consultant paediatric radiologists. This “one stop clinic” allows quicker diagnosis and treatment plans.


Additional services include endoscopies, radiological investigations such as MRI small bowel scans and transit marker studies (provided by nearby Spire Gatwick Park Hospital) and phlebotomy services for patients of all ages. Dr. Hii’s dedication to providing exceptional care and his innovative approach to paediatric gastroenterology have established him as a trusted expert in his field. His commitment to advancing diagnostic and treatment options ensures patients receive comprehensive and compassionate care tailored to their needs.
