Functional Gastrointestinal Disorders: Causes, Symptoms, and Management Strategies

Functional gastrointestinal disorders (FGIDs) are prevalent, affecting approximately 40% of individuals worldwide.

As we progress into 2025, there’s a notable shift towards holistic health approaches, with 22% of Americans prioritizing gut health and digestion.

This trend underscores the importance of understanding FGIDs, especially for those pursuing careers in healthcare through licensed practical nursing schools.

What Are Functional Gastrointestinal Disorders?

FGIDs, also known as disorders of gut-brain interaction, are conditions where the gastrointestinal (GI) tract appears normal but doesn’t function properly. Common FGIDs include:

  • Irritable Bowel Syndrome (IBS): Characterized by abdominal pain, bloating, and altered bowel habits.
  • Functional Dyspepsia: Involves upper abdominal discomfort, fullness, and nausea.
  • Functional Constipation and Diarrhea: Chronic issues with bowel movements without an identifiable cause.

Causes and Symptoms

The exact causes of FGIDs are multifactorial, involving:

  • Gut-Brain Axis Dysregulation: Miscommunication between the central nervous system and the GI tract.
  • Altered Gut Motility: Abnormal movement of the digestive tract leading to symptoms.
  • Visceral Hypersensitivity: Increased sensitivity to pain within the GI tract.
  • Psychosocial Factors: Stress and anxiety can exacerbate symptoms.

Symptoms vary but often include:

  • Abdominal Pain and Discomfort
  • Bloating and Gas
  • Constipation, Diarrhea, or Both
  • Nausea and Early Satiety

Management Strategies

Managing FGIDs requires a comprehensive approach:

  • Dietary Modifications:
    • Low-FODMAP Diet: Reducing fermentable carbohydrates to alleviate symptoms.
    • Increased Fiber Intake: Incorporating soluble fiber to support digestion.
  • Lifestyle Changes:
    • Regular Physical Activity: Enhances gut motility and reduces stress.
    • Stress Management Techniques: Practices like meditation and yoga to improve gut-brain interaction.
  • Medical Therapies:
    • Probiotics and Prebiotics: Balancing gut microbiota for improved GI function.
    • Medications: Such as antispasmodics or laxatives, tailored to individual symptoms.
  • Psychological Interventions:
    • Cognitive Behavioral Therapy (CBT): Addresses the psychological aspects contributing to FGIDs.
    • Gut-Directed Hypnotherapy: Shown to improve symptoms in IBS patients.

For those enrolled in licensed practical nursing programs, understanding these management strategies is crucial for patient education and care.
