Fibromyalgia: Common Symptoms, Causes and Treatments


Fibromyalgia is a long-term condition that affects millions around the world, often causing persistent pain throughout the body, overwhelming fatigue, and cognitive challenges.

Fibromyalgia is recognized as a chronic pain disorder characterized by heightened sensitivity to pain, disturbed sleep, memory issues, and frequent fatigue. Unlike other rheumatic diseases, it doesn’t cause inflammation or deterioration in the muscles or joints. Instead, it disrupts the way the nervous system interprets and amplifies pain signals.

Diagnosing fibromyalgia can be complex because its symptoms often resemble those of other conditions, such as chronic fatigue syndrome or autoimmune disorders. Diagnosis typically involves a thorough clinical examination and eliminating other possible causes.

Functional Medicine and Fibromyalgia: Uncovering the Root Causes

In functional medicine, fibromyalgia is approached as a condition influenced by multiple underlying factors. This perspective looks beyond surface symptoms and focuses on identifying deeper imbalances that may contribute to its development or severity.

  1. Gluten Sensitivity
    Even in individuals without celiac disease, gluten may provoke inflammation that worsens fibromyalgia symptoms. Eliminating gluten from the diet has helped many patients reduce fatigue and digestive issues.
  2. Candida Imbalance
    An overgrowth of Candida — a yeast naturally present in the digestive tract — can lead to pain, mental fog, and nutrient malabsorption. Addressing this imbalance can improve overall wellbeing.
  3. Thyroid Disorders
    Many individuals with fibromyalgia also experience hypothyroidism. Low thyroid hormone levels may cause fatigue, weight gain, and mood disturbances. Treating thyroid dysfunction can significantly enhance symptom control.
  4. Nutrient Deficiencies
    Low levels of vitamin D, magnesium, and omega-3 fatty acids are frequently observed in fibromyalgia patients. These deficiencies may intensify pain, disturb sleep, and impair immune response. Nutritional supplementation is often recommended.
  5. Gut Dysbiosis: SIBO and Leaky Gut
    Small Intestinal Bacterial Overgrowth (SIBO) and increased gut permeability (leaky gut) can allow bacteria and toxins to enter the bloodstream, triggering widespread inflammation. Healing the gut lining and restoring microbial balance are central goals in functional treatment.
  6. Adrenal Dysfunction
    Chronic stress can lead to adrenal fatigue, affecting cortisol levels and contributing to exhaustion and poor sleep. Supporting adrenal health through lifestyle changes and nutrition is essential for recovery.
  7. Mold Toxins (Mycotoxins)
    Exposure to mold-related toxins may affect respiratory health, cognitive clarity, and amplify physical pain. Identifying and eliminating mold exposure can provide relief for many patients.
  8. Heavy Metal Toxicity
    Toxins such as mercury can interfere with brain chemistry and pain regulation. Detoxification strategies help reduce the body’s toxic burden and may lessen symptom intensity.
  9. MTHFR Gene Mutations
    Certain genetic variations in the MTHFR gene can impair the body’s ability to process B vitamins and detoxify effectively. Targeted nutritional support can help manage symptoms related to inflammation and energy deficits.
  10. Low Glutathione Levels
    Glutathione is a critical antioxidant for cellular repair and detoxification. Many fibromyalgia patients show depleted levels, making it harder for their bodies to manage oxidative stress. Supporting glutathione production may improve immune function and resilience.
Common Symptoms of Fibromyalgia

This condition presents a wide range of symptoms, many of which overlap with other chronic illnesses. Key symptoms include:

  • Widespread muscle and joint pain, often described as deep, aching, or burning
  • Persistent fatigue that doesn’t improve with rest
  • Mental fog or difficulty with focus and memory (“fibro fog”)
  • Digestive disturbances, including bloating, gas, and constipation
  • Frequent headaches or migraines
  • Painful menstrual cramps, which are often more intense and long-lasting than typical cramps
Treatment Options for Fibromyalgia

Common treatment strategies include:

  • Gentle physical activities such as yoga, swimming, or walking
  • Acupuncture to reduce pain and improve circulation
  • Massage therapy for muscle relaxation
  • Chiropractic care for alignment and tension relief
  • Cognitive Behavioral Therapy (CBT) for coping with stress and mood symptoms
  • Stress management techniques including meditation and breathwork
  • Physical therapy to rebuild strength and mobility
