What Does a Gastroenterologist Do?
Gastroenterologists specialise in disorders of the digestive system, including the oesophagus, stomach, intestines, liver, and pancreas. Dr. Kumanan is experienced in diagnosing and managing a wide range of conditions, from reflux and irritable bowel syndrome to liver disease and gastrointestinal cancers.

On any given day, a gastroenterologist may:
Perform colonoscopies to screen for bowel cancer
Manage liver conditions like hepatitis or fatty liver disease
Remove polyps or early tumours using minimally invasive techniques
Treat bile duct or pancreatic issues using ERCP
Investigate chronic abdominal symptoms or GI bleeding
Work with multidisciplinary teams to optimise patient care

Approach to Care
Dr. Kumanan’s care philosophy is grounded in precision and purposeful communication. He approaches each case with a balance of technical skill and clinical judgement, taking time to ensure patients understand not just the ‘what’ but the ‘why’ behind every step. His manner is calm, his decisions deliberate – reflecting a practice built on long-term care outcomes.
