😵💫 Struggling with insomnia? It’s not just in your head.
Sleep issues are often a symptom of something deeper going on in the body.
Here are 6 common root causes of insomnia we uncover in functional medicine:
1. Histamine Intolerance or MCAS
High histamine can spike at night, leading to anxiety, restlessness, itching, or racing thoughts.
2. Hormone Imbalance
Low progesterone, low growth hormone, or estrogen swings (especially during perimenopause) can all impact your ability to fall or stay asleep.
3. Blood Sugar Dysregulation
If you wake up between 2–4am, your blood sugar might be crashing — triggering cortisol to wake you up.
4. Neuroinflammation
Chronic infections (like Lyme or mold), toxic exposure, or head trauma can inflame the brain and disturb sleep architecture.
5. Gut Dysbiosis
Your gut produces key sleep neurotransmitters like serotonin and GABA. Imbalance here = restless nights.
6. Cortisol Imbalance
High cortisol in the evening? You'll feel wired instead of tired. This is classic HPA axis dysfunction.
👉 Tired of tossing, turning, and relying on melatonin or sleep meds?
It’s time to find out why your body can’t rest.
