What Is a Long COVID Doctor?
Through treating hundreds of patients over the past three years, we’ve witnessed how targeted therapies can restore function when patients have been told “there’s nothing more we can do.”
The Root Causes We Treat
Most clinics stop at chasing symptoms. At The COVID Institute, we go deeper—because Long COVID is not random. It follows patterns, driven by SIX root causes that affect multiple systems in the body. By identifying and treating these root problems, patients finally begin to see real recovery.
ROOT CAUSE #1: Dysautonomia & Vagus Nerve Dysfunction – Your autonomic nervous system should automatically control things like heart rate, blood pressure, and digestion. In Long COVID, it often goes haywire—causing dizziness, racing heart, gut trouble, and even breathing changes. We use targeted therapies to reset and rebalance your vagus nerve and nervous system.
ROOT CAUSE #2: Mitochondrial Dysfunction – Mitochondria are your cells’ “power plants.” When they stop working properly, you’re left with crushing fatigue, muscle weakness, and poor recovery after activity. We help repair and recharge mitochondria so your body can produce energy again.
ROOT CAUSE #3: Gut Dysbiosis & Leaky Gut – A disrupted gut microbiome and damaged gut lining can trigger bloating, food sensitivities, brain fog, and widespread inflammation. We rebuild gut health to restore balance, calm the immune system, and improve nutrient absorption.
ROOT CAUSE #4: Mast Cell Activation & Histamine Intolerance –
Mast cells are immune “alarm” cells. In Long COVID, they often stay stuck in overdrive, releasing histamine and causing rashes, flushing, food reactions, and allergy-like symptoms. We calm mast cell activity so your body stops overreacting.
ROOT CAUSE #5: Endothelial Dysfunction (Blood Vessel Injury & Microclots) – COVID damages the inner lining of blood vessels, creating tiny clots and reducing oxygen delivery to tissues. This contributes to fatigue, chest pain, shortness of breath, and brain fog. Our treatments target blood vessel healing and microclot resolution.
ROOT CAUSE #6: Hormone Imbalance – COVID can throw off thyroid, adrenal, and sex hormones, leading to insomnia, mood swings, low libido, irregular cycles, and poor stress tolerance. We identify and correct these imbalances to restore energy, mood, and stability.
Why This Matters: By treating the drivers of Long COVID—not just the symptoms—you get more than temporary relief. You get a path toward lasting recovery.
