The main focus of Jason’s practice is in the treatment of gastrointestinal conditions, both acute and chronic - such as irritable bowel syndrome, ulcerative colitis, Crohn’s disease, gluten-related disorders, peptic ulcer disease, intestinal parasites, and fructose intolerance. But he also has significant experience in treating a wide range of non-gastrointestinal conditions.
Dr Hawrelak did his Honours (First Class) and PhD degrees in the areas of the gastrointestinal microbiota, irritable bowel syndrome and the clinical applications of pre- and probiotics and has written extensively in Australian and international textbooks and journals on these topics – including Pizzorno and Murray’s Textbook of Natural Medicine (3rd and 4th editions) and the Australian texts Clinical Naturopathy: An Evidence-based Guide (1st and 2nd editions) and Herbs and Natural Supplements: an Evidence-based Guide (4th edition). A list of Jason’s’ other publications is below, with links to some of the articles.
He has been an invited peer-reviewer for the British Medical Journal, Chemotherapy, Medical Journal of Australia, Journal of Gastroenterology and Hepatology, Annals of Gastroenterology and Hepatology, Journal of Medicine and Medical Sciences, and the Journal of Medicinal Food.
For 5 years, until it ceased publication, Jason co-wrote the popular ‘Journal Digest’ section of the Journal of Complementary Medicine, where he screened hundreds of recently published articles evaluating the therapeutic potential of natural medicines, and chose a handful for more extensive review in the journal. So, whilst Jason has a great level of expertise in the gastroenterology area, he is also familiar with the broader evidence-based natural medicine field.
Dr Hawrelak has lectured at both the undergraduate and postgraduate level for over 15 years and is widely known for his engaging and entertaining lecturing style, as well as for his capacity to make complex information easily understood and, most importantly, clinically relevant. He regularly presents to other health professionals and has been a popular speaker for the Health Masters Live series - where he has presented his Gastrointestinal Masterclass 1 on two occasions, was the key presenter in the Gastrointestinal Mastercalsss 2, and presented his lecture on Managing Paediatric Gastrointestinal Conditions and Building a Healthy Gut within the Natural Paediatrics Masterclass.
