About of Guy D. Eslick

Guy D. Eslick is a Gastroenterologist based in Sydney, NSW, Australia. He works with people who have gut and digestion problems, plus issues that affect the liver, gallbladder, and bile ducts. If you’ve been dealing with ongoing symptoms like tummy pain, reflux, bowel changes, or trouble swallowing, he can help sort out what’s going on in many cases.


In day-to-day care, he looks after a mix of common and more serious conditions. This can include irritable bowel syndrome (IBS), indigestion, diarrhoea, gastritis, and peptic ulcer disease. He also treats reflux and GERD, including Barrett oesophagus, which is something doctors keep an eye on over time.


For problems involving the gallbladder and bile flow, he manages things like gallstones, gallbladder disease, cholecystitis, choledocholithiasis, and cholangitis. Some patients come in after gallbladder removal or when symptoms don’t quite settle after treatment. Liver conditions are also part of the picture, including cirrhosis, autoimmune hepatitis, hepatitis, and non-alcoholic fatty liver disease.


He also treats more complex cases, including pancreatitis and bile-related illnesses. Where needed, he supports care plans for people with conditions such as acute pancreatitis and cholecystitis. At times, patients are referred when there are concerns about cancers of the gut, such as colorectal cancer, stomach cancer, and oesophageal cancer. In these situations, follow-up and clear next steps matter, and that’s where endoscopy and colonoscopy can play a key role.


Guy D. Eslick provides services that include endoscopy and colonoscopy, along with help for problems linked to H. pylori infection. He also cares for people dealing with long-term digestive issues like coeliac disease and malabsorption, as well as ongoing symptom management. It’s often a mix of assessment, tests, and practical treatment decisions, depending on the cause and how you’re feeling.


Details about training history, specific research, and clinical trials aren’t listed here, but his work focuses on getting to the root of digestive and liver concerns and helping patients move forward with a plan they can understand.
