Irritable bowel syndrome: dietary interventions.

Area of Science:

• Gastroenterology
• Dietary Science
• Clinical Research

Background:

• Irritable bowel syndrome (IBS) affects 5-20% of the population.
• IBS is linked to abnormal gut function, visceral hypersensitivity, and psychosocial factors.
• Individuals with IBS have higher rates of comorbid conditions and unnecessary surgeries.

Purpose of the Study:

• To systematically review the effects of dietary modifications on irritable bowel syndrome (IBS).
• To evaluate the efficacy of a gluten-free diet and a low-FODMAP diet for IBS management.

Main Methods:

• A systematic overview of existing literature was conducted.
• Searches were performed in major medical databases up to June 2014.
• Included studies were appraised for quality, with a focus on randomized controlled trials (RCTs).

Main Results:

• The review identified and evaluated relevant studies on dietary interventions for IBS.
• Three RCTs met the inclusion criteria for the overview.
• Additional RCTs were considered for commentary, even if not meeting strict inclusion criteria.

Conclusions:

• The systematic overview categorized the efficacy of two key dietary interventions for IBS.
• Effectiveness and safety data were analyzed for gluten-free and low-FODMAP diets.
• Dietary modification shows potential as a management strategy for IBS.
