About
My name is Dr Ng Yi Kang
MBBS (S'pore), MRCP (UK), MMed (Int Med), FAMS (Gastroenterology)
I am a Consultant Gastroenterologist and Hepatologist with clinical interests in functional gastrointestinal disorders, gastro-oesophageal reflux disease (GERD), colorectal cancer screening, diagnostic and therapeutic endoscopy, and advanced gastrointestinal physiology testing. In my practice, I place strong emphasis on understanding each patient’s symptoms carefully before recommending investigations or treatment.
I graduated from the Yong Loo Lin School of Medicine, National University of Singapore, and completed my specialist training in Gastroenterology and Hepatology under the SingHealth Residency Programme. I have trained and worked across several major public healthcare institutions in Singapore, including Singapore General Hospital, Changi General Hospital, and Sengkang General Hospital.
Before entering private practice, I served as a Consultant Gastroenterologist and Hepatologist at Sengkang General Hospital, where I was the clinical lead for functional gastrointestinal disorders. During this time, I was involved in developing and introducing advanced oesophageal diagnostic services.
I perform gastroscopy and colonoscopy, including colorectal cancer screening, polyp detection and removal, and therapeutic endoscopy. I am also involved in medical education as a Clinical Assistant Professor with Duke-NUS Medical School. Outside of medicine, I have a keen interest in endurance sports and cycling, having completed multiple Ironman 70.3 triathlons and won the 2022 OCBC National Individual Time Trial Championships.

Digestive care that starts with understanding
Digestive symptoms can be frustrating, persistent, and difficult to explain. Bloating, reflux, abdominal pain, altered bowel habits, and indigestion often require more than a quick answer.
With me, your care begins with careful listening and a structured understanding of your symptoms. Investigations and procedures are used thoughtfully, with treatment guided by clinical evidence, physiology, and the individual patient.

Care for irritable bowel syndrome, bloating, functional dyspepsia, abdominal discomfort, and bowel habit changes.
