Dr Lim has more than 20 years of clinical experience. He obtained his MBBS from National University of Singapore in 2000, and MRCP (UK) in 2004. He subsequently underwent advanced specialist training in Gastroenterology in National University Hospital, Singapore. He was accredited as a specialist in Gastroenterology by the Specialist Accreditation Board in 2008, after which he obtained the Fellowship of Royal College of Physicians (Edinburgh) and the Fellowship of Academy of Medicine.


Dr Lim’s area of special interest is advanced endoscopic imaging in the early detection, diagnosis and management of gastrointestinal cancer and pre-cancer. He received the Health Manpower Development Programme (HMDP) award conferred by Ministry of Health for one year of specialized training in advanced endoscopic imaging including endoscopic ultrasound and endoscopic ultrasound guided- fine-needle aspiration and biopsy/injection from 2009 to 2010 in Germany at Universitätsmedizin der Johannes Gutenberg-Universität Mainz and Technical University of Munich (TUM) University Hospital Klinikum rechts der Isar. In 2009, Dr Lim received a scholarship for clinical attachment at Kyushu University Hospital, Japan, which focused on advanced endoscopic imaging for cancer detection and endoscopic management of gastrointestinal pre-cancer and cancer.

Dr Lim has vast experience in the management of a wide spectrum of gastrointestinal and liver conditions. He is proficient in endoscopic ultrasound, endoscopic ultrasound guided fine needle aspiration and biopsy (to diagnose and manage conditions such as cancer or diseases of the pancreas, unexplained lymph node enlargement and submucosal tumours of the digestive tract), endoscopic ultrasound guided injection (eg celiac plexus block which is the injection of drugs into intra-abdominal nerves to relieve pain), endoscopic mucosal resection, gastroscopy, colonoscopy, ligation of hemorrhoids and small intestine examination using capsule endoscopy and balloon enteroscopy, among other procedures.


His training and experience in the specialized field has led to multiple publications in top international journals (including Cancer Cell, Gastroenterology, Gut, Gastrointestinal Endoscopy and Endoscopy), presentations at international meetings, and research grant and awards, including the Young Investigator Award at the Asia Pacific Digestive Week, and Posters of Distinction at Digestive Disease Week in USA. He has been invited as faculty for Gastroenterology courses and endoscopy workshops. He has written chapters for numerous medical books, and is on the editorial board of BMJ Open Gastroenterology, published by the British Medical Journal in partnership with the British Society of Gastroenterology.


Dr Lim believes in doing his best for his patients. When Dr Lim was in National University Hospital, he received the Excellent Service Star Award, Excellent Service Gold Award and the SSU Award for top compliments. When Dr Lim was practicing as a gastroenterologist in Raffles Hospital from 2014 to 2021, he also received the Service Star award.


Dr Lim was an Assistant Professor at National University of Singapore, and consultant gastroenterologist at National University Hospital, where he was clinical director. He was heavily involved in nurturing and training Gastroenterology trainees as the post-graduate training director. As the pioneering Programme Director of the ACGME-I Gastroenterology Fellowship Programme in NUH, he developed from scratch the ACGME-I training curriculum for Gastroenterology trainees. In recognition of his role in training the newer generation of doctors, he was given the National Healthcare Group Excellence Award For Teaching, and was selected and sponsored by the World Gastroenterology Organization for the Train-the-Trainers Workshop in Porto, Portugal.
