Asian consensus on irritable bowel syndrome.

Area of Science:

• Gastroenterology
• Epidemiology
• Clinical Medicine

Background:

• Irritable bowel syndrome (IBS) research is predominantly Western-based, with limited understanding of its relevance in Asian societies.
• Asian experts' perspectives and data from Asian studies are crucial for a comprehensive understanding of IBS.

Purpose of the Study:

• To highlight key data from Asian IBS studies.
• To articulate Asian experts' views on IBS.
• To provide a guide for healthcare professionals in Asia regarding IBS.

Main Methods:

• A multinational group of Asian physicians specializing in IBS contributed statements.
• A modified Delphi approach was used to assess evidence quality and agreement levels.
• Statements covered IBS symptoms, diagnosis, epidemiology, infection, pathophysiology, motility, management, and diet.

Main Results:

• Bloating and meal-associated symptoms were common in Asian IBS patients.
• Female predominance was not observed in most Asian countries; faster intestinal transit times were noted in some populations.
• Dietary factors like chili and lactose malabsorption were perceived as triggers, though evidence was weak; psychological distress had weak links to healthcare seeking.

Conclusions:

• This compilation underscores the distinct experiences of IBS patients in Asia.
• It emphasizes the need for regionally specific approaches to IBS understanding and management.
