[Functional gastrointestinal disorders].

Area of Science:

• Gastroenterology
• Psychiatry
• Primary Care Medicine

Background:

• Functional gastrointestinal disorders (FGID) account for approximately 50% of chronic gastrointestinal symptoms in primary care.
• Common FGID include functional dyspepsia and irritable bowel syndrome, characterized by heterogeneity in symptoms, impairment, and pathophysiology.
• The biopsychosocial model and the Rome Foundation define FGID as disorders of brain-gut interaction.

Purpose of the Study:

• To highlight challenges in FGID diagnosis and management, including physician hesitancy and patient reluctance.
• To emphasize the importance of interdisciplinary, evidence-based guidelines for improving diagnostic certainty and therapeutic options.
• To provide recommendations for patient education and establishing a trusting doctor-patient relationship.

Main Methods:

• Diagnosis relies on characteristic symptom clusters and exclusion of organic gastrointestinal disorders per guidelines.
• Management follows a graduated approach based on main symptoms, patient impairment, and preferences.
• Treatment strategies include education, dietary modifications, pharmacological interventions, and psychological therapies.

Main Results:

• Interdisciplinary guidelines enhance diagnostic confidence and expand therapeutic choices for FGID.
• Guidelines offer strategies for effective patient communication, fostering trust and acceptance of the FGID diagnosis.
• A structured, symptom-based management plan improves patient outcomes.

Conclusions:

• Evidence-based guidelines are crucial for optimizing the diagnosis and management of functional gastrointestinal disorders.
• A biopsychosocial approach, integrated with patient-centered care, is essential for addressing FGID effectively.
• Effective communication and graduated treatment plans are key to successful FGID management.
