Why am I being referred to a Gastroenterologist?

A gastroenterologist is a specialist doctor who helps with all gastroenterology needs and diagnosing and managing a variety of conditions. When a patient has symptoms relating to their organs in the gastrointestinal tract, including the stomach, oesophagus, large and small bowels, liver, gallbladder and pancreas, they will often be referred to a gastroenterologist.

What are common symptoms?

Diarrhoea, constipation, difficulties swallowing, heartburn, abdominal pain. Patients with a family history of colon cancer or bowel polyps can also be referred to a gastroenterologist.

What do I bring to my appointment?

New patients will be required to complete a registration form at their first visit. We also ask you please bring the following documentation to assist the staff:

  • Insurance card
  • Referral documents
  • A list of current medications (if any)
  • Recent blood test results
  • Recent x-ray results (such as upper GI series, barium enema, ultrasound, or CT scans of the abdomen or pelvis)
  • Copies of past medical records (these may have already been sent to our specialists by your doctor)
