What is long COVID — and why are so many people still struggling months or even years after infection?
In this episode of the Harmony With Food Show, Meg Marie O’Rourke, registered dietitian and functional nutritionist, breaks down the science behind long COVID, post-viral syndrome, and lingering symptoms that conventional lab work often misses.
More than 20 million Americans are living with post-COVID conditions, including fatigue, brain fog, digestive issues, heart palpitations, dizziness, food intolerances, and nervous system dysregulation. Many are told their labs are “normal.” But normal labs do not always mean optimal health.
In this episode, Meg explains:
• What long COVID actually is and why symptoms can develop even after a mild or asymptomatic infection
• How the autonomic nervous system (fight-or-flight vs. rest-and-digest) becomes dysregulated
• The connection between long COVID and gut inflammation
• Post-infectious IBS and microbiome disruption
• Neurovascular coupling and brain-blood flow communication
• Why stacking supplements is not the answer
• How functional nutrition testing provides clarity
The gut and brain are deeply connected. When the nervous system is dysregulated, digestion suffers. When the microbiome is disrupted, inflammation increases. Fix the gut, fix the brain. Fix the brain, fix the gut.
This episode also addresses the dangers of “miracle” supplement marketing and why natural does not automatically mean safe or effective. Precision matters. Testing matters.
At Harmony With Food, we say: Test. Don’t guess. If you are experiencing long COVID symptoms, post-viral fatigue, chronic inflammation, digestive distress, or unexplained brain fog, this episode provides structured, science-based guidance rooted in functional nutrition.
