A gastroenterologist is a physician who specializes in the treatment of problems related to the gastrointestinal tract (including the oesophagus, stomach, small and large intestine) and other digestive organs (liver, pancreas, bile ducts, and gallbladder). Gastroenterologists see patients in the hospital and clinic, and also perform endoscopic procedures (e.g., upper endoscopy and colonoscopy).

Why do I need to see a gastroenterologist?

If you are above 45 years and have digestive problems such as frequent abdominal pain, nausea, diarrhoea, constipation, or heartburn, you need to see a gastroenterologist.

Do gastroenterologists perform surgery?

No. Gastroenterologists perform endoscopic procedures but do not perform surgery. When necessary, they work closely with surgeons.

What therapeutic procedures does a gastroenterologist perform?

Gastroenterologists perform Endoscopic Therapeutic procedures like Personal Endoscopic Myotomy (POEM) for Achalasia Cardia, Anti-Reflux Mucosectomy (ARMS) for the treatment of patients with Gastroesophageal reflux diseases and Interventional EUS procedures like Cyst Drainage, EUS guided Biliary Drainage, etc.
