Understanding Irritable Bowel Syndrome: A Comprehensive Guide
Irritable Bowel Syndrome (IBS) is a common functional gastrointestinal disorder characterized by chronic abdominal pain, bloating, and altered bowel habits in the absence of identifiable structural or biochemical abnormalities (Latif et al., 2020; Mayer, 2008). It affects 10–20% of adults and adolescents worldwide, with women being disproportionately affected—14–24% in females and 5–19% in males (Coss-Adame & Rao, 2014; Longstreth et al., 2006; Al-Attar, 2020).
IBS is diagnosed using the ROME IV Criteria, which defines IBS as:
• Recurrent abdominal pain, at least 1 day per week for the last 3 months, associated with two or more of the following:
• Related to defecation
• Associated with change in stool frequency
• Associated with change in stool form (Ng et al., 2023)
