Functional Medicine Approach to POTS Syndrome: Comprehensive Care for Lasting Wellness

Postural Orthostatic Tachycardia Syndrome (POTS) is a complex condition that often leaves patients feeling frustrated with conventional treatment approaches that don’t address the root cause of their symptoms. At the Toronto Integrative and Functional Medicine, our approach, led by Dr. Mordy Levy, offers a more personalized path to health by investigating the underlying mechanisms that contribute to POTS, such as autonomic nervous system (ANS) dysregulation, food intolerances, nutritional deficiencies, mitochondrial dysfunction, and potential hormonal imbalances.

Understanding POTS and Its Underlying Mechanisms

POTS is primarily characterized by a dysregulation of the autonomic nervous system (ANS), leading to an exaggerated heart rate response when standing. This condition disproportionately affects women, which suggests hormonal imbalances may also play a significant role. In addition to ANS dysfunction, mitochondrial dysfunction—the energy powerhouses of our cells—can exacerbate fatigue, dizziness, and other symptoms. Hormonal fluctuations, particularly around menstrual cycles, menopause, or conditions like endometriosis, may further complicate the clinical picture of POTS in women.

Recommended Lab Tests in Functional Medicine for POTS

Functional medicine delves deep into understanding the multi-system involvement in POTS. Comprehensive lab testing provides insight into the root causes and individual variations in each patient’s case. Commonly recommended tests include:

1. Autonomic Nervous System Testing – Evaluates the function of the parasympathetic and sympathetic branches of the ANS.
2. Comprehensive Hormonal Panel – Especially for female patients, examining levels of estrogen, progesterone, cortisol, and thyroid hormones can reveal imbalances that may contribute to symptoms.
3. Mitochondrial Function Tests – Markers such as ATP production, oxidative stress, and CoQ10 levels can assess energy metabolism issues.
4. Nutritional Deficiencies – Comprehensive micronutrient testing to identify deficiencies in vitamins such as B12, magnesium, and CoQ10, which are crucial for energy and nervous system health.
5. Cardiovascular Testing – Measuring heart rate variability (HRV) and other cardiovascular markers to assess ANS balance and cardiovascular function.
6. Inflammatory Markers – High-sensitivity C-reactive protein (hs-CRP) and other markers can help evaluate underlying inflammation that may worsen POTS symptoms.
7. Gut Health Assessment – As the gut-brain axis plays a vital role in ANS regulation, stool analysis can be useful in identifying dysbiosis or intestinal permeability issues.
8. Adrenal Function Testing – A salivary cortisol/DHEA panel can assess adrenal function, especially relevant for patients experiencing chronic stress or adrenal exhaustion.

Initial Basic Protocol for POTS in Functional Medicine

An individualized treatment plan is at the core of functional medicine’s approach to POTS. While the following protocol offers a foundational plan, each patient’s protocol is tailored based on lab results and their unique presentation.

1. Mitochondrial Support: Supplements like CoQ10, PQQ, and magnesium support energy production at the cellular level, improving fatigue and exercise tolerance.
2. Autonomic Nervous System Regulation: Techniques such as biofeedback, heart rate variability training, and mindfulness-based stress reduction can help re-regulate the ANS.
3. Hormonal Balance: For women, supporting estrogen and progesterone balance, often with bioidentical hormones or herbs like Vitex, can stabilize hormonal fluctuations contributing to POTS symptoms.
4. Nutritional Support: A diet rich in antioxidants and anti-inflammatory foods is recommended. Elimination of inflammatory foods such as refined sugar, processed foods, and gluten is crucial to reduce systemic inflammation that can exacerbate POTS symptoms. Magnesium-rich foods, omega-3s, and adequate hydration with electrolyte support are also essential.
5. Compression Stockings: Wearing compression stockings can help prevent blood pooling in the lower extremities and improve circulation, reducing symptoms like dizziness and fatigue.
6. Adrenal and Cardiovascular Health: Herbs like Ashwagandha and Rhodiola can help modulate stress responses, while low doses of beta-blockers or low-dose naltrexone (LDN) may be considered for cardiovascular symptom management.
7. Lifestyle Modifications: Incorporating low-intensity, gradual exercise such as walking or swimming, along with adequate rest, is key for long-term recovery.

Dr. Levy’s Unique Qualifications

Dr. Mordy Levy’s training spans four distinct yet complementary medical disciplines—Conventional Medicine (MD), Naturopathic Medicine (ND), Chiropractic Medicine (DC) and Homeopathic Medicine (HOM)—positioning him as an expert in comprehensive yet holistic and integrative healthcare. His ability to blend traditional diagnostic methods with functional medicine protocols ensures that patients receive a well-rounded and evidence-based treatment plan. Dr. Levy’s extensive experience in autonomic dysfunction, mitochondrial health, and hormone balancing gives him the advanced knowledge needed to manage POTS with a comprehensive and personalized approach.

Conclusion

At the Toronto Integrative and Functional Medicine clinic, we understand the challenges faced by patients with POTS and aim to address the condition at its root through functional medicine principles. Dr. Levy’s multidisciplinary training enables him to offer an integrative solution that considers the interplay between ANS dysregulation, mitochondrial dysfunction, nutritional deficiencies, toxic load, and hormonal imbalances, especially for the women who are disproportionately affected by this condition. If you or a loved one is struggling with POTS, reach out to our clinic for a thorough evaluation and a tailored treatment plan that addresses your unique health needs.
