vagus nerve pots dysautonomia

The Three Faces of POTS: A Clinical Map of Hyperadrenergic, Neuropathic, and Hypovolemic Subtypes

POTS is one diagnosis with at least three distinct physiologies. Treating them as one condition is one of the most common reasons patients stay sick. The subtype determines the protocol.

vagus nerve internal vibrations tremor

Internal Vibrations and Body Buzzing: The Symptom That Confuses Every Clinician

Patients describe a humming, buzzing, or vibrating sensation that no one else can feel. It is real, it has identifiable mechanisms, and it is increasingly tied to dysautonomia, small fiber neuropathy, and mast cell activation rather than psychiatric causes.

vagus nerve cervical instability dysautonomia

Cervical Instability and Vagal Compression: The Hidden Structural Driver of Dysautonomia

A 2025 Frontiers in Neurology paper coined the term "cervicovagopathy" — vagus nerve dysfunction with a structural etiology in the upper cervical spine. For some dysautonomia patients, the autonomic problem is downstream of a mechanical one.

vagus nerve nausea gastroparesis

Chronic Nausea: When the Vagus Nerve Loses Its Grip on the Gut

Persistent nausea without a clear surgical or pharmacological cause is most often a vagal motility problem — and recent open-label studies of non-invasive vagus nerve stimulation in gastroparesis are now showing measurable improvement in symptoms and gastric emptying.

vagus nerve dizziness pppd

Chronic Dizziness Without a Diagnosis: PPPD and the Vestibulo-Autonomic Link

When the workup is "normal" but the dizziness persists, the answer is often PPPD — a chronic functional vestibular disorder driven by a brain stuck in postural threat detection, with autonomic and vagal dysregulation as the engine.

vagus nerve eds hypermobility

The Hypermobility Trifecta: hEDS, POTS, and MCAS — Why the Vagus Nerve Is the Bridge

Hypermobile EDS, POTS, and MCAS travel together in a way that purely structural or purely immune models cannot explain. The bridge that ties all three together is autonomic — and the vagus nerve is the central player.

vagus nerve cirs mold

Mold Toxicity, CIRS, and the Autonomic Collapse: Why the Vagus Goes Silent

Biotoxin illness produces a measurable autonomic phenotype — low HRV, orthostatic instability, and chronic vagal underactivation — that explains why so many CIRS patients fail to recover even after exposure ends.

vagus nerve mcas mast cell

MCAS and the Vagal Brake: Why Mast Cells Need a Quiet Nervous System

Mast cells are wired into the autonomic nervous system. When the vagal brake fails, mast cells become reactive — and the cholinergic anti-inflammatory pathway emerges as one of the most underused tools in MCAS care.

Dysautonomia and the Vagus Nerve: A Practical Guide

Dysautonomia is a confusing diagnosis with overlapping symptoms — racing heart, dizziness, GI trouble, brain fog. Here’s how to think about it through the vagus nerve, and what helps.

POTS and Tachycardia: When Your Heart Races and the Room Spins

POTS is one of the fastest-growing diagnoses in young adults. Here’s the autonomic mechanism behind it, and the vagal training that genuinely helps.

Low Blood Pressure and Vasovagal Symptoms: The Other Side of Vagal Imbalance

Most articles talk about strengthening the vagus nerve. But sometimes vagal tone is too high, too quickly — leading to fainting, dizziness, and dropping blood pressure. Here’s the other half of the story.

Long COVID, Chronic Fatigue, and Post-Viral Vagal Dysfunction

Many of the strangest, most disabling symptoms of long COVID and chronic fatigue point to a single common pathway — a vagus nerve that hasn’t recovered from a viral hit. Here’s what helps.
