Irritable bowel syndrome: the clinical approach

Area of Science:

• Gastroenterology
• Internal Medicine
• Clinical Review

Background:

• Irritable bowel syndrome (IBS) is a chronic, debilitating functional gastrointestinal disorder.
• Characterized by abdominal pain and altered bowel habits, IBS affects 9-23% of the population, predominantly females.
• Its multifactorial pathogenesis involves environmental and host factors, with management posing significant challenges.

Purpose of the Study:

• To provide an updated overview of IBS epidemiology, pathogenesis, diagnosis, and treatment.
• To highlight the importance of physician-patient relationships in managing IBS.
• To discuss current therapeutic strategies, including non-pharmacological and pharmacological options.

Main Methods:

• This is a clinical review synthesizing current knowledge on IBS.
• Information was gathered from existing literature on epidemiology, pathogenesis, diagnosis, and treatment modalities.
• The review focuses on evidence-based approaches for IBS management.

Main Results:

• IBS diagnosis relies on symptom identification and exclusion of organic disease.
• Non-pharmacological therapies, including lifestyle and dietary modifications, are crucial first-line options.
• Pharmacological treatment should be tailored to predominant symptoms, with careful drug titration and evaluation.

Conclusions:

• Effective IBS management necessitates a comprehensive approach tailored to individual patient needs.
• Lifestyle modifications and dietary changes are foundational therapeutic strategies.
• Personalized pharmacotherapy, guided by symptom presentation and response, is essential for optimal outcomes.
