Patient Information
A curated library of patient information resources covering endoscopy, bowel and liver conditions, and inflammatory bowel disease.
All fact sheets below are produced and maintained by GESA, Australia's leading professional body for gastroenterology and hepatology. The information is general and is not a substitute for personalised medical advice — please discuss your specific situation with Dr Choi.
Gastroscopy is a test procedure done using an endoscope, which is a long, thin, flexible tube with a 'video camera' at the tip. This tube is passed through the mouth into the oesophagus (food pipe), stomach and first part of the small intestine.
Download PDFA colonoscopy (scope) is the examination of the lower gastrointestinal tract to diagnose, and in some cases, treat problems. Colonoscopy can detect polyps, inflamed tissues and cancers, such as colorectal cancer. It can help doctors diagnose unexplained changes in bowel habits, abdominal pain, bleeding from the bowel and weight loss.
Download PDFBowel preparation empties and cleans the bowel before a colonoscopy or surgery. A thoroughly clean bowel is essential for an adequate examination — any residual stool can hide polyps or early cancers and may mean the procedure needs to be repeated sooner. Following the prep instructions carefully gives Dr Choi the best possible view and the most accurate result from your procedure.
Download PDFCapsule endoscopy is also known as pill-camera or wireless endoscopy.
Download PDFEndoscopic retrograde cholangiopancreatography, or ERCP, is a specialised procedure used to examine the ducts, or 'drainage tubes', of the gall bladder, pancreas and liver.
Download PDFEndoscopic ultrasound (EUS) is an endoscopic procedure that uses an ultrasound probe added to the tip of an endoscope. It gives the doctor an endoscopic view and allows detailed ultrasound examination of the organs surrounding your upper gut, including the pancreas, bile duct, gallbladder, liver and spleen.
Download PDFFlexible sigmoidoscopy uses a flexible tube with a 'video camera' at the tip to inspect the lining of the rectum, anus and lower part of the colon (bowel).
Download PDFA bowel polyp is an abnormal fleshy growth extending from the inner wall of the large bowel (colon and rectum).
Download PDFYour diet and lifestyle choices, as well as screen and surveillance, can influence your risk of getting bowel cancer.
Download PDFConstipation is a common complaint in Australia and other developed countries. Up to one in five adults report that they have constipation, although only a minority of people seek medical attention.
Download PDFDiverticular disease is a common condition in which small pouches or 'pockets' (known as diverticula) form in the lining of the large bowel or colon. When there are multiple diverticula, this is known as diverticulosis. Diverticulitis is when the diverticula become inflamed or infected.
Download PDFThe liver is the body's largest internal organ and has many essential functions.
Download PDF'Fatty liver disease' describes conditions characterised by the accumulation of excess fat in the liver. When too much fat is stored in the liver, it can lead to liver scarring, or 'cirrhosis'. Fatty liver is very common and can affect more than 1 in 3 Australians.
Download PDFGallstones (biliary calculi) are small pebble-like substances that form in the gallbladder. They can block the normal flow of bile if they move from the gallbladder and lodge in any of the ducts (tube-like passageways) that carry bile from the liver to the small intestine.
Download PDFReflux is also known as 'acid reflux' or 'gastro-oesophageal reflux'. When your stomach contents rise up, or 'reflux', into your oesophagus (food pipe), you can have an uncomfortable burning feeling or discomfort in your chest.
Download PDFHelicobacter pylori (H. pylori) is a bacterium (germ) that can infect the human stomach. The bacterium lives in the lining of the stomach, and the chemicals it makes inflame the stomach lining.
Download PDFIron deficiency is when the amount of iron in your body becomes too low, which happens when your body's iron needs are not met by the iron you get from your diet, or you lose too much iron over time.
Download PDFLactose is a sugar that naturally occurs in the milk made by all mammals, including cows, sheep and goats. It is made of two individual sugar molecules (glucose and galactose) joined together.
Download PDFThe Low FODMAP Diet, when followed under dietitian guidance through restriction, reintroduction and personalisation phases, helps manage irritable bowel syndrome symptoms by reducing poorly absorbed carbohydrates that trigger gut symptoms.
Download PDFInflammatory bowel disease (IBD) is a term used to describe two main diseases: ulcerative colitis and Crohn's disease, which cause inflammation of the bowel. This inflammation is thought to be due to an imbalance of the immune system, and is not due to an infection.
Download PDFIn general, most patients with IBD should follow the Australian Guide to Healthy Eating, and do not need to restrict their diet. However, there is emerging or established evidence to support specialty diets for specific situations.
Download PDFUp to 50% of people with inflammatory bowel disease (IBD) experience psychological distress associated with their illness. This fact sheet explains how your physical and mental health are linked, the types of psychological problems you might experience, and the support options available to you.
Download PDFA stoma is a surgically made opening in the abdominal wall to attach the small or large bowel. Bowel output then drains into a specially designed disposable collection bag.
Download PDFIBD may impact on physical and emotional aspects of sexual health, regardless of your sexual orientation or relationship status. Whilst you may shy away from talking about this topic, it is important to remember that this is a normal and essential part of maintaining your quality of life and your IBD team can guide you in navigating any concerns.
Download PDFInflammatory bowel disease (IBD) can often be managed with medication alone. However, a proportion of patients may require surgery, and the decision for this involves you and a multidisciplinary team of doctors, surgeons and other members of your IBD team.
Download PDFYou may find the thought of traveling daunting when you have inflammatory bowel disease (IBD). With careful planning, it should be possible for you to travel safely to most places for both short and long holiday.
Download PDFThe management of inflammatory bowel disease (IBD) may include drugs that suppress your immune system. Before commencing treatment with a drug that alters your immune system, your IBD team will check your immunity to certain diseases and may ask you to undergo vaccination.
Download PDFComplementary and alternative therapies encompass a range of medicinal, psychological or physical therapies that are not considered conventional treatment.
Download PDFPrintable management plan templates to record your medications, monitoring tests, and action steps during a flare.
Aminosalicylates (5-ASAs) are a group of medications used to treat IBD. There are many medications within the group, including mesalazine, balsalazide, olsalazine and sulfasalazine.
Download PDFSteroids (corticosteroids) can effectively treat active inflammation in inflammatory bowel disease (IBD), but due to their side effects, they are not recommended to be used repeatedly or long-term. Other effective therapies can reduce the need for steroid medications.
Download PDFThiopurines (azathioprine and mercaptopurine) are medications that are used to treat IBD, including Crohn's disease and ulcerative colitis.
Download PDFMethotrexate is an effective medication used to treat inflammatory bowel disease (IBD) and is generally taken once a week. Regular blood test monitoring ensures side effects can be detected and addressed promptly.
Download PDFAdalimumab is a complex biologic drug known as a monoclonal antibody. Monoclonal antibodies can target very specific parts of your immune system to control inflammation. Adalimumab targets a molecule called tumour necrosis factor-alpha (TNF-α).
Download PDFInfliximab is a complex biologic drug known as a monoclonal antibody that targets tumour necrosis factor-alpha (TNF-α) to control inflammation. It is used to treat moderate to severe Crohn's disease and ulcerative colitis.
Download PDFGolimumab is a complex biologic drug known as a monoclonal antibody that targets tumour necrosis factor-alpha (TNF-α). It is used to treat moderate to severe ulcerative colitis when other medications have not worked or are not suitable.
Download PDFUstekinumab is a complex biological drug known as a monoclonal antibody. It targets interleukin proteins (IL-12 and IL-23) to help control inflammation.
Download PDFVedolizumab is a complex biological drug known as a monoclonal antibody. It targets a protein found specifically in the bowel to help control inflammation.
Download PDFTofacitinib is a drug known as a Janus Kinase (JAK) inhibitor. JAKs are enzymes that trigger the immune response causing inflammation in ulcerative colitis; blocking them reduces bowel inflammation and allows healing.
Download PDFUpadacitinib is a medicine known as a 'Janus kinase (JAK) inhibitor'. JAKs are enzymes that trigger the immune response causing inflammation in IBD; blocking them reduces bowel inflammation and allows healing.
Download PDFOzanimod is a medicine known as a 'sphingosine 1-phosphate (S1P) receptor modulator'. The S1P receptor plays an important role in the immune response that drives inflammation in ulcerative colitis.
Download PDFEtrasimod is an oral medication used to treat moderate to severe ulcerative colitis that works by modulating the immune system to reduce bowel inflammation, and requires regular monitoring due to potential side effects.
