Gastroenterology.
Gastroenterology consultations at Excelsia, based at Earlwood. Assessment and management of digestive tract, liver and gallbladder conditions. GP referral required for the Medicare rebate.
From oesophagus to colon.
Gastroenterology is the medical specialty focused on the digestive tract, from the oesophagus to the colon, and on the liver, gallbladder and pancreas. Gastroenterologists diagnose and manage a wide range of conditions, from common issues like reflux and irritable bowel syndrome through to inflammatory bowel disease, hepatitis, fatty liver disease, and pancreatic disorders.
Care is coordinated with your GP. Your GP identifies the concern, prepares a referral, and continues general care while the specialist advises on the digestive or liver question.
Common reasons GPs refer.

History, exam, a plan.
Bring your GP referral, any recent test results (bloods, imaging, endoscopy reports), a list of your current medications, and any hospital or previous specialist letters relevant to the reason for referral.
- A detailed history including symptoms, dietary patterns, family history and lifestyle factors.
- A clinical examination.
- Review of any tests you've already had.
- A management plan that may include further investigation, dietary changes, medication, and follow-up.
- Where a scope is indicated (endoscopy, colonoscopy or similar), it's organised from this consultation and booked at a day-surgery or hospital facility.

Do I need to see a GP first?
Yes. A GP referral is required for the Medicare rebate to apply.
Will I need a colonoscopy or endoscopy?

What should I bring?
Your GP referral, recent test results, medication list, and any hospital or previous specialist letters.
Are liver concerns covered?
Yes. Liver assessment, including liver function abnormalities, fatty liver and hepatitis, is part of gastroenterology practice at Excelsia.
How urgent is a referral?
Referrals are triaged based on clinical priority. Your GP indicates urgency in the referral letter.
