What Does a Gastroenterologist Treat?
A gastroenterologist is a specialist in the diagnosis and treatment of disorders affecting the digestive system — including the oesophagus, stomach, small intestine, colon, rectum, and the liver, pancreas and biliary system. In Singapore, a qualified gastroenterologist holds the Membership of the Royal College of Physicians (MRCP) and the FAMS (Fellowship of the Academy of Medicine Singapore) in Gastroenterology, after completing at least 3 years of specialist training in a recognised programme.
- Digestive disorders: GERD (acid reflux), peptic ulcers, irritable bowel syndrome (IBS), inflammatory bowel disease (Crohn's disease, ulcerative colitis)
- Colorectal conditions: Colorectal cancer, polyps, diverticular disease (referred for joint surgical management)
- Liver diseases: Non-alcoholic fatty liver disease (NAFLD/NASH), viral hepatitis (B & C), liver cirrhosis, liver cancer (HCC), autoimmune hepatitis
- Biliary and pancreatic conditions: Gallstones, primary biliary cholangitis, pancreatitis
- Endoscopy procedures: Gastroscopy, colonoscopy, polypectomy, endoscopic variceal ligation, capsule endoscopy, ERCP
- Liver transplantation: Pre- and post-transplant hepatology, immunosuppression management
When Should You See a Gastroenterologist?
- Persistent heartburn or difficulty swallowing — could indicate GERD, Barrett's oesophagus, or stricture
- Rectal bleeding or black, tarry stools — requires urgent investigation
- Unexplained weight loss with digestive symptoms — potential malignancy must be excluded
- Chronic abdominal pain or bloating unresponsive to standard treatment
- Jaundice (yellowing of skin or eyes) — indicates liver, bile duct or pancreatic pathology
- Abnormal liver function tests — requires specialist evaluation of cause and stage
- Age 50+ (or earlier with family history) — colorectal cancer screening colonoscopy recommended

Frequently Asked Questions — Gastroenterology in Singapore
Is colonoscopy covered by Medisave in Singapore?+
Yes. Diagnostic colonoscopy and therapeutic procedures such as polypectomy are Medisave-claimable in Singapore at MOH-accredited facilities. The amount claimable depends on the procedure code and your Medisave balance. Screening colonoscopies for eligible individuals may also qualify under the Screen for Life programme.
How often should I have a colonoscopy in Singapore?+
The Health Promotion Board recommends colorectal cancer screening from age 50 for average-risk individuals. If no polyps are found, repeat colonoscopy is recommended every 10 years. Those with polyps, family history, or IBD may require more frequent surveillance. Consult your gastroenterologist for a personalised screening plan.
What is fatty liver disease and can it be reversed?+
Non-alcoholic fatty liver disease (NAFLD) occurs when excess fat accumulates in the liver without significant alcohol consumption. Early-stage fatty liver can often be reversed through lifestyle modifications — weight loss, dietary changes, and exercise. Advanced stages (NASH, fibrosis) require specialist management and monitoring. A FibroScan or liver biopsy may be needed to assess severity.
What is the difference between Hepatitis B and Hepatitis C?+
Both are viral infections affecting the liver. Hepatitis B is most commonly transmitted perinatally or through blood contact, and most adults clear it spontaneously. Chronic Hepatitis B has no cure but can be managed with antiviral therapy. Hepatitis C is typically acquired through blood contact and is now curable in over 95% of cases with direct-acting antivirals taken for 8–12 weeks.
What are the symptoms of liver cancer (HCC) in Singapore?+
Hepatocellular carcinoma (HCC) is often asymptomatic in early stages. Symptoms in advanced disease include unexplained weight loss, abdominal pain or fullness (especially on the upper right), jaundice, and fatigue. Individuals with chronic Hepatitis B, cirrhosis, or NASH are at elevated risk and should undergo 6-monthly ultrasound surveillance.
