Although IBS does not cause permanent damage to the bowel, its symptoms can fluctuate over time and often resemble those of other digestive conditions. Abdominal pain, bloating and changes in bowel habits may occur individually or together, making professional assessment essential to exclude inflammatory bowel disease, coeliac disease, bowel cancer and other gastrointestinal disorders before confirming an IBS diagnosis.
Australian healthcare data also demonstrates the widespread impact of digestive disorders. The Australian Institute of Health and Welfare reports that digestive system diseases are a major health burden in Australia, leading to over $4.5 billion in annual health system spending, highlighting the importance of investigating ongoing gastrointestinal symptoms rather than assuming they are harmless. Understanding what are the symptoms of IBS helps patients recognise when persistent bowel changes require assessment by an experienced gastroenterologist and when further investigations such as colonoscopy or specialised testing may be appropriate.
