🧠 What Is Functional Medicine?

Functional medicine is a systems-based, root-cause approach to health. It often includes:

• Extensive lifestyle and nutritional interventions

• Gut health, inflammation, and hormone balancing

• Personalised lab tests

• Use of supplements and sometimes herbal medicine

• Emphasis on long appointments and listening to patient history

It’s sometimes practised by conventionally trained doctors who’ve moved toward a holistic model.

📊 What Evidence Supports It?

✅ Areas with Evidence Backing:

1. Nutrition and Anti-inflammatory Diets

   • Strong evidence that Mediterranean-style and low-inflammatory diets improve outcomes in:

     • Asthma

     • Rheumatoid arthritis

     • IBS

     • Type 2 diabetes

     • Depression

   • Functional medicine often emphasises whole-food diets, removal of triggers (gluten, dairy), and gut healing.

2. Mind-Body Practices

   • Meditation, breathwork, cognitive-behavioural therapy (CBT), and trauma-informed care show clear benefits for:

     • Anxiety and depression

     • Chronic pain and fatigue

     • Breathing-related anxiety

   • These are often core components of integrative or functional care.

3. Supplement Use

   • Evidence supports:

     • Vitamin D for immunity and asthma support (including ABPA)

     • Magnesium for muscle and nerve health

     • B12 and folate in neuropathy

     • Omega-3s for inflammation

   • Functional medicine practitioners often use lab-guided supplementation.

4. Patient-centred care model

   • Evidence shows longer consultations, continuity of care, and active listening improve outcomes in chronic illness, even without radical therapies.

❌ Where Evidence Is Weaker or Emerging:

• Many supplement protocols and “gut healing” programs are not yet backed by large clinical trials.

• Some tests used in functional medicine (e.g., food intolerance panels, microbiome mapping) lack standardisation and clinical validation.

• Functional medicine can be very expensive, and quality varies a lot between practitioners.

• Some critics argue it can promote over-testing and unnecessary restrictions.

📚 Scientific Studies & Reviews

🩺 So—Should You Consider It?

Possibly yes, if:

• You’re looking to reduce reliance on medications like corticosteroids

• You want to explore nutrition, breathwork, and natural anti-inflammatory strategies

• You work with a qualified, experienced practitioner who respects your current treatments and doesn’t ask you to stop them

But approach with caution, if:

• You’re being sold expensive supplements, unvalidated tests, or restrictive diets without clear rationale

• You’re being advised to abandon proven therapies like antifungals or steroids without a safe taper

✅ How to Proceed Safely:

• Choose a practitioner who is medically trained (e.g. GP, nurse, or naturopathic doctor with evidence-based credentials)

• Ask for collaboration with your respiratory or infectious disease team

• Focus on nutrition, anxiety management, physical rehab, and reducing inflammation as starting points

• Be skeptical of miracle cures or overly rigid protocols
