Functional Dyspepsia: Diagnostic and Therapeutic Approaches

Area of Science:

• Gastroenterology
• Functional Gastrointestinal Disorders

Background:

• Functional dyspepsia (FD) is a prevalent gastroduodenal disorder characterized by epigastric pain and postprandial distress.
• Diagnosis relies on symptom patterns (epigastric pain syndrome or post-prandial distress syndrome) without structural abnormalities.
• Extensive investigations are generally not recommended for FD unless alarm features are present.

Purpose of the Study:

• To review the evidence supporting various therapeutic approaches for functional dyspepsia.
• To provide a basis for effective functional dyspepsia treatment strategies.
• To emphasize personalized management based on symptom severity and impact on quality of life.

Main Methods:

• Review of established pharmacologic and non-pharmacologic therapies for functional dyspepsia.
• Analysis of etiopathologic factors including micro-inflammation, infections, motility, hypersensitivity, brain-gut axis, and psychological factors.
• Emphasis on evidence-based treatment recommendations.

Main Results:

• Multiple etiopathologic factors contribute to functional dyspepsia symptoms.
• A diverse range of therapeutic interventions, including pharmacologic and psychological approaches, are available.
• Treatment efficacy is influenced by underlying mechanisms and individual patient factors.

Conclusions:

• Functional dyspepsia management requires a tailored approach considering symptom patterns and severity.
• Integrating pharmacologic and non-pharmacologic interventions optimizes treatment outcomes for functional dyspepsia.
• Personalized functional dyspepsia treatment enhances patient function and quality of life.
