Peter I. Wu is a gastroenterologist based at St George Hospital in Sydney, NSW. He works with people who need help with problems in the digestive system, and sometimes with swallowing issues that can come from conditions in the throat and head and neck area.
In clinic and hospital settings, Peter helps look after patients with things like gastroesophageal reflux disease (GERD), where acid reflux can cause burning, discomfort, and ongoing irritation. He also treats people with achalasia, a swallowing problem that can make it hard to move food and drinks down into the stomach.
At times, care also involves the way the throat works. This can include swallowing difficulty, and follow-up that may be needed after a laryngectomy. For some people, changes after treatment in the head and neck area can affect how well they chew, swallow, and keep their weight stable. Peter focuses on getting the right plan in place to support everyday eating and drinking.
When tests are needed, Peter performs or arranges endoscopy and colonoscopy. These are common ways to check what is going on inside the digestive tract. They can be used to investigate symptoms, look for causes of ongoing pain or changes in bowel habits, and help guide treatment from there.
He also cares for people with head and neck squamous cell carcinoma (HNSCC), especially when swallowing and nutrition are part of the bigger picture. That might mean coordinating with the rest of the care team so things line up, including how the gut and throat issues affect each other.
Over time, Peter has built experience in managing both the usual digestive problems and the knock-on effects that can come with swallowing difficulties. He takes a practical approach, aiming to keep things clear and manageable. The goal is usually to improve comfort, help people eat and drink safely, and make sure follow-up is on track.
Peter also keeps an eye on newer care approaches where they fit best in real life. If clinical trials are available and relevant for a person’s situation, he can discuss options as part of the overall care plan. Education and training help form the base for this work, with a focus on safe, up-to-date endoscopy and thoughtful patient care.
