POTS & Dysautonomia Specialist Serving the Fargo-Moorhead Region
POTS patients in the Fargo-Moorhead area face a significant barrier: no local specialist who understands the full autonomic-immune-inflammatory picture. Cardiologists manage the tachycardia. Neurologists assess the autonomic function. Immunologists investigate the antibodies. No one investigates all three simultaneously — or looks at the mast cell, gut, or connective tissue drivers that are often upstream of all of them. As a POTS and dysautonomia specialist near Fargo ND, Dr. Paul M. Bekkum, DC, CCEP provides a systems-level functional medicine investigation designed to find what individual specialists miss.
POTS — Moorhead MN
In-person POTS and dysautonomia consultations at 22 6th Street North, Moorhead MN 56560. Initial visits include a full IFM Matrix assessment, autonomic history review, and functional lab panel design including autoimmune antibody and mast cell markers.
Dysautonomia — Fargo ND
Fargo-area POTS patients travel to Integrix Health for a comprehensive root-cause investigation that their local cardiologist or neurologist is not equipped to provide. POTS functional medicine near Fargo ND means investigating what triggered your autonomic dysfunction — not just managing its symptoms.
Telehealth — ND & MN
Many POTS patients cannot sustain prolonged upright travel during flares. Telehealth consultations and ongoing protocol management are available throughout North Dakota and Minnesota — making functional medicine accessible regardless of your orthostatic tolerance on any given day.
What Drives POTS
The Five Root Causes Functional Medicine Investigates in POTS
POTS is not a single disease — it is a clinical syndrome defined by dysautonomia (autonomic nervous system dysfunction) that can arise from several distinct biological mechanisms. Identifying which mechanism is primary in a given patient determines which intervention will be effective. The five most common functional medicine-identified POTS drivers are:
- Autoimmune Dysautonomia — autoantibodies against adrenergic (alpha-1, beta-1, beta-2) and muscarinic (M2, M3, M4) receptors impair autonomic signaling. These antibodies can be triggered by infection, including EBV and COVID-19. Measurable via specialized autonomic antibody panels.
- Mast Cell Activation Syndrome (MCAS) — mast cells release histamine, prostaglandins, and other vasoactive mediators that cause vascular instability, fluid shifts, and autonomic dysregulation. MCAS is found in a substantial percentage of POTS patients and often coexists with hEDS/HSD.
- Hypovolemia & Blood Volume Dysregulation — reduced plasma volume is documented in many POTS patients. Drivers include aldosterone deficiency, excessive sodium excretion, and inadequate fluid intake. Renin-aldosterone panel and 24-hour urine assessment identify this driver.
- Connective Tissue Hypermobility (hEDS/HSD) — hypermobile Ehlers-Danlos syndrome and hypermobility spectrum disorders cause vascular laxity that allows excessive venous pooling in the lower extremities when upright, directly triggering the orthostatic tachycardia response.
- Post-Infectious Neurological Injury — viral illnesses including EBV, COVID-19, and enteroviruses can trigger autonomic neuropathy through direct nerve damage or via autoimmune antibody generation. Post-COVID POTS has been widely documented since 2020.
A 2021 study in Nature Cardiovascular Research found autoantibodies against adrenergic and muscarinic receptors in a significant proportion of POTS patients — providing a mechanistic explanation for autoimmune-mediated dysautonomia that functional medicine protocols can target through immune regulation strategies.

The Overlap Picture
POTS, Hashimoto's, Fibromyalgia & ME/CFS — Why These Conditions Often Coexist
Many POTS patients are also diagnosed with Hashimoto's thyroiditis, fibromyalgia, ME/CFS, and mast cell activation syndrome. This is not coincidence — these conditions share overlapping biological mechanisms that functional medicine's systems-level approach is uniquely suited to address simultaneously.
Shared Immune Dysregulation
Autoimmune activity — whether directed at thyroid tissue (Hashimoto's), autonomic receptors (POTS), or driving systemic neuro-inflammation (fibromyalgia, ME/CFS) — reflects a common upstream failure of immune self-tolerance. Addressing gut permeability, molecular mimicry, and genomic immune variants benefits all of these conditions simultaneously.
Mast Cell as a Common Thread
Mast cell activation syndrome is found in elevated rates among patients with POTS, hEDS, ME/CFS, and fibromyalgia. Mast cell-derived histamine and prostaglandins drive vascular instability (POTS), pain amplification (fibromyalgia), fatigue (ME/CFS), and immune dysregulation — making MCAS investigation a priority in patients with overlapping presentations.
Autonomic Dysfunction Across Conditions
Small fiber neuropathy, reduced heart rate variability, and autonomic dysregulation are documented across fibromyalgia, ME/CFS, and POTS patient populations. The IFM Matrix approach maps the full autonomic and neurological burden — allowing a coordinated intervention that improves autonomic tone across all overlapping diagnoses rather than addressing each in isolation.
Common Questions
POTS & Dysautonomia — Frequently Asked Questions
What is POTS and how is it diagnosed?
POTS (Postural Orthostatic Tachycardia Syndrome) is an autonomic nervous system disorder defined by a heart rate increase of 30+ beats per minute within 10 minutes of standing, without a corresponding drop in blood pressure. It is typically confirmed with a tilt table test or active stand test. Symptoms include dizziness, lightheadedness, palpitations, fatigue, brain fog, nausea, and near-syncope when upright. Functional medicine's role is not to re-diagnose POTS but to investigate why — identifying the specific autoimmune, mast cell, hypovolemic, or connective tissue mechanism driving the autonomic dysfunction in each patient.
Can functional medicine help POTS?
Yes — and it is particularly valuable for POTS because conventional cardiology and neurology manage symptoms (beta-blockers, fludrocortisone, increased fluid and salt) without investigating root causes. Functional medicine investigates the autoimmune antibodies, mast cell activation, blood volume dysregulation, and inflammatory triggers that sustain autonomic dysfunction — allowing interventions that address the mechanism rather than only the downstream tachycardia. For autoimmune POTS, immune regulation strategies. For MCAS-driven POTS, low-histamine protocols. For hypovolemic POTS, mineralocorticoid and electrolyte optimization.
Is POTS connected to Hashimoto's or fibromyalgia?
Yes — substantial clinical overlap exists between POTS, Hashimoto's thyroiditis, fibromyalgia, ME/CFS, and mast cell activation syndrome. These conditions share underlying mechanisms: autoimmune dysregulation, autonomic nervous system sensitization, mast cell hyperreactivity, and connective tissue fragility. Many POTS patients carry two or more of these overlapping diagnoses. Integrix Health's IFM Matrix approach is specifically designed to address these overlapping presentations as a unified biological picture rather than treating each diagnosis in isolation.
What does POTS treatment look like at Integrix Health?
The initial POTS evaluation includes an IFM Matrix assessment, autonomic antibody panel, mast cell marker testing, renin-aldosterone panel, viral reactivation panel, inflammatory markers, thyroid full panel, and 3x4 Genetics SNP analysis. Based on findings, the intervention is tailored to the primary driver — immune regulation for autoimmune POTS, low-histamine dietary protocol and mast cell stabilizers for MCAS, electrolyte and aldosterone pathway support for hypovolemic POTS. Vagal tone support — including heart rate variability training and parasympathetic dietary protocols — is incorporated across all presentations.
Can I do POTS consultations via telehealth from Fargo, ND?
Yes. Telehealth consultations for POTS and dysautonomia are available throughout North Dakota and Minnesota. Given that POTS symptoms are often worsened by prolonged upright activity (including travel), telehealth is frequently the most appropriate format for initial evaluation and ongoing follow-up. Lab work can be ordered to local draw locations (LabCorp, Quest, or hospital outreach) without requiring travel to Moorhead.
