How to Use the IBS Risk Checker
Irritable bowel syndrome (IBS) is a chronic digestive condition marked by recurring abdominal pain and changes in bowel habits, without a structural abnormality behind it. This checker is based on the Rome IV criteria, the internationally recognized diagnostic framework for IBS, weighing pain frequency, symptom duration, and three bowel-related features together.
Under the Rome IV criteria, IBS becomes a real possibility when abdominal pain occurs at least once a week for three months or more, and that pain is tied to defecation or accompanied by at least two of a change in bowel frequency or a change in stool form. Based on how closely your answers match these criteria, this tool reports your likelihood as low, possible, or high.
Keep in mind this result is a screening reference only and does not replace a medical diagnosis. Abdominal pain and bowel changes can also stem from other causes, including colorectal cancer, inflammatory bowel disease, or thyroid conditions — so if you notice warning signs like unexplained weight loss or blood in your stool, or symptoms simply persist, see a gastroenterologist for a proper evaluation and any needed testing.
