Prebiotics and probiotics are heavily marketed as effective supplements in improving gut health and overall physical health, yet there is often confusion with regards to the exact benefits these supplements actually provide. Gastrointestinal symptoms are a common complaint amongst cancer survivors, ranging from mucositis, chemotherapy-induced diarrhea to gut graft versus host disease amongst bone marrow transplant recipients.
Trials involving the use of probiotics have shown some promising results in terms of improving such symptoms, but it is not clear what probiotic type and dose would achieve benefit in a given patient. There are also safety concerns about triggering harmful bacterial infections in heavily immunocompromised patients , as probiotic products are afterall live bacterial cultures. Fibre supplements, while rich in prebiotics, may exacerbate bloating and abdominal discomfort in certain patients unaccustomed to a high-fibre diet. So are prebiotics and probiotics necessarily friends or can they be foes ?

Assoc Prof Quah Thuan Chong

Senior Consultant, Division of Paediatric Haematology and Oncology, Department of Paediatrics

Associate Professor, Department of Paediatrics, Yong Loo Lin School of Medicine
National University of Singapore

Associate Professor Quah Thuan Chong grew up in the island of Penang (a beautiful city off the western coast of West Malaysia) and came to another island (another beautiful island off the southern coast of West Malaysia) in 1971 to study medicine at the then University of Singapore.


He was captivated and inspired by Professor Wong Hock Boon, the "walking encyclopaedia" and "the smartest man I've ever known personally" whose motto is "if you want to do paediatrics, you've got to live paediatrics, eat paediatrics, sleep paediatrics". He was also inspired by the children he got to know when he was doing his housemanship (internship) in 1976 in the University Department of Paediatrics (then at the Mistri Wing in the Singapore General Hospital).

Then and there, he decided to spend the rest of his life looking after kids. After spending a very happy one year in the paediatric department in Alexandra Hospital under another wonderful mentor, Dr Tan Keng Wee, he went back to the University's Department of Paediatrics, and has been there ever since (moving together with the department to the National University Hospital in 1986).

He started to devote his life to paediatric haematology and oncology in 1983, training under Professor Wong, and also in Australia and Jerusalem (under Professor Shimon Slavin, for marrow transplant, under whose guidance he did the first bone marrow transplant in Singapore).

He is the recipient of the National Medical Excellence Awards 2013 (National Outstanding Clinician Mentor Award).
