It’s important to get a medical diagnosis
The only way to know for sure if you’re experiencing IBS (or something more sinister like irritable Bowel Disease) is to get a diagnosis from a medical professional. In most cases, the diagnosis, will be based on what’s called the Rome IV criteria.
These criteria state a person needs to have abdominal pain at least one day per week for three months. And that pain needs to be associated with their bowel movements.
In applying the criteria, your GP or specialist will explore whether there is an anatomical reason for your bowel problems, such as inflammatory bowel disease (IBD), celiac, infections, and cancer.
