If you notice symptoms such as diarrhea, constipation, abdominal cramps, bloating, bubble gut, or frequent belching, which intensify especially in stressful situations, it is worth seeing a gastroenterologist. Irritable bowel syndrome (IBS) is diagnosed using the so-called Rome IV Diagnostic Criteria, which include: abdominal pain present for at least 1 day a week in the past 3 months (if symptoms have been observed for at least 6 months before diagnosis), accompanied by at least 2 out of 3 symptoms associated with: bowel movements, changes in the appearance and texture of stools, and changes in the frequency of bowel movements. You must remember that there is no single test that will clearly diagnose IBS. Symptoms of irritable bowel syndrome are similar to those of other diseases, so diagnosing it can be difficult and may require further testing to rule out other diseases one by one.
