Anxiety and stress are not just “mental health “ issues in functional medicine. They are viewed as signals that one or more body systems may be out of balance. The goal is to identify and address the underlying contributors rather than simply suppress symptoms.
Common Root Causes of Anxiety and Stress
1. Blood sugar imbalances
*Skipping meals or eating excess refined carbohydrates can cause blood sugar swings.
*Symptoms may include anxiety, shakiness, irritability, fatigue, and panic-like episodes
2. Gut Health
*About 90% of the body’s serotonin is produced in the gut.
*Gut dysbiosis, intestinal permeability (“leaky gut”), inflammation, or food sensitivity may contribute to anxiety and mood changes.
3. Nutrient Deficiency
Common deficiencies associated with anxiety include:
✔️Magnesium
✔️Vitamin D
✔️Vitamin B-12
✔️Folate
✔️Vitamin B 6
✔️Zinc
✔️Omega 3-fatty acids
✔️Iron (when deficient)
4. Adrenal Stress & HPA Axis Dysregulation
Common stress can disrupt cortisol rhythms leading to:
😩Morning fatigue
😩Afternoon crashes
😩Difficulty sleeping
😩Feeling “wired but tired”
😩Increased anxiety
5. Thyroid Dysfunction
Even mild thyroid imbalance may contribute to:
⚠️Anxiety
⚠️Depression
⚠️Brain Fog
⚠️Fatigue
⚠️Palpitations
6. Hormone Imbalances
Fluctuations in
🧐Estrogen
🧐Progesterone
🧐Testosterone
🧐DHEA
Can all influence mood, particularly during perimenopause and menopause.
7. Chronic inflammation
Inflammation increases cytokines that affect brain chemistry and can worsen anxiety and depression.
