What is Irritable Bowel Syndrome (IBS)?

Irritable Bowel Syndrome, commonly referred to as IBS, is a functional gastrointestinal disorder characterized by abdominal pain or discomfort associated with changes in bowel habits. Symptoms may include bloating, diarrhea, constipation, or both.

The condition affects millions of people worldwide and can significantly impact quality of life due to its chronic nature and unpredictable symptoms.

Rome IV Criteria for IBS Diagnosis

The Rome IV criteria provide a standardized set of diagnostic guidelines for IBS, ensuring consistency across different healthcare settings. These criteria focus on the presence of specific gastrointestinal symptoms over time.

To meet the criteria for IBS, individuals must experience abdominal pain or discomfort at least 12 weeks in the past year, associated with two or more of the following: changes in stool frequency, changes in stool form (e.g., hard/lumpy vs. loose/watery), and mucus in the stool.
