Dietary factors in functional dyspepsia

Area of Science:

• Gastroenterology
• Digestive Health
• Clinical Nutrition

Background:

• Functional dyspepsia (FD) presents with upper gastrointestinal symptoms, often triggered by meals.
• Current understanding emphasizes motor dysfunction and visceral hypersensitivity, but dietary influences are under-explored.
• Existing treatments inadequately address meal-induced symptom exacerbation in FD.

Purpose of the Study:

• To review the significance of dietary factors in the etiology and management of functional dyspepsia.
• To highlight the underappreciated role of food intake patterns, nutrient composition, and food intolerances in FD.
• To advocate for the integration of dietary considerations into FD treatment strategies.

Main Methods:

• Literature review focusing on studies examining dietary factors in functional dyspepsia.
• Analysis of research on nutrient intake, food intolerances, and eating behaviors in relation to FD symptoms.
• Synthesis of evidence on the impact of dietary interventions on FD management.

Main Results:

• Dietary factors, including nutrient intake and food intolerances, play a significant, yet often ignored, role in FD symptom generation.
• Abnormalities in gastric motor function show a weak correlation with FD symptoms, suggesting other contributing factors.
• Visceral hypersensitivity is recognized, but dietary triggers are frequently overlooked in clinical practice.

Conclusions:

• Dietary factors are critically relevant to functional dyspepsia and warrant greater clinical attention.
• Understanding individual responses to specific foods and macronutrients is crucial for effective FD management.
• Future FD treatments should incorporate personalized dietary approaches to address meal-induced symptoms.
