Guidelines for Approaching Functional Medicine
Functional medicine should be approached as a patient-centered, holistic model that addresses underlying causes of disease rather than focusing solely on symptom management, with implementation through multidisciplinary teams using evidence-based interventions tailored to individual patient needs.
Core Principles of Functional Medicine
- Functional medicine is a real and potentially beneficial approach that recognizes the complex interplay between physical and psychological health, occupational participation, and quality of life 1
- The model emphasizes addressing root causes of disease rather than just managing symptoms, taking a more personalized and collaborative approach to healthcare 2
- Treatment should focus on activity-based (functional) rather than impairment-based goals and interventions 1
Implementation Guidelines
Assessment Approach
- Begin with empathic recognition that functional disorders are real and disabling conditions 1
- Take time to listen to the patient's story and build therapeutic rapport before implementing interventions 1
- Conduct comprehensive evaluations that consider physical, psychological, and environmental factors affecting health 3
- Clearly define treatment parameters and introduce self-management concepts at initial assessment 1
Treatment Framework
- Implement multidisciplinary rehabilitation approaches with coordinated care between specialists 1
- Provide clear education about the diagnosis and symptoms to both patients and their significant others 1
- Use variability of symptoms positively in treatment planning and implementation 1
- Sensitively challenge unhelpful thoughts, beliefs, and behaviors that may impede recovery 1
Specific Intervention Strategies
For functional movement disorders:
For functional neurological disorders:
Nutritional Approaches
- Consider supervised elimination diets under the direction of trained functional medicine dietitians 3, 4
- Integrate nutritional interventions with education about other modifiable lifestyle factors 3
- Monitor and document improvements in patient-reported outcomes throughout nutritional interventions 3, 4
Evidence-Based Outcomes
- Functional medicine approaches have demonstrated improvements in:
Common Pitfalls and Cautions
- Avoid uncritical acceptance of poorly documented diagnostic procedures or ineffective therapies 6
- Be aware that the complex functional medicine model lacks standardization, which can lead to non-rigorous clinical reasoning 6
- Recognize that while functional medicine shows promise, many approaches have reasonable underlying science but lack rigorous clinical testing 6
- Maintain open and consistent communication with patients and other healthcare professionals about treatment approaches 1
- Complete relapse prevention and ongoing self-management plans as part of treatment 1
Documentation and Communication
- Provide clear written documentation describing the patient's diagnosis, symptom variability, functional impact, and support needs 1
- Use "to whom it may concern" letters to help patients navigate systems and access appropriate resources 1
- Schedule follow-up appointments to review progress, troubleshoot issues, and reset goals as needed 1
