Managing Long COVID and POTS: A Functional Medicine Approach

As the global health community continues to confront the lasting effects of Covid-19, more individuals are experiencing the persistent symptoms of Long Covid. One particularly challenging manifestation of Long Covid is Postural Orthostatic Tachycardia Syndrome (POTS), a condition that affects the autonomic nervous system and can lead to symptoms like dizziness, fatigue, and an abnormally high heart rate when standing up. Managing this condition, especially in the context of Long Covid, requires a comprehensive, multi-faceted approach.

Functional medicine offers a unique perspective on tackling the complexities of Long Covid and POTS by looking beyond the surface symptoms and addressing underlying causes, whether they are viral, bacterial, hormonal, or related to inflammation. This article outlines some of the approaches that have been considered in recent clinical cases, drawing attention to the potential treatments and diagnostic tools that are proving effective in managing these conditions.

A Complex Picture: The Symptoms of Long Covid and POTS

Individuals with Long Covid often report a wide range of symptoms. These can include chronic fatigue, gastrointestinal issues, brain fog, neurological disturbances (such as tinnitus and sensations of vibrations in the body), and autonomic dysfunction, including POTS. The overlap of these symptoms can make diagnosis and treatment a challenge. A common theme in many Long Covid cases is the sensation of adrenaline surging through the body, an indicator of dysregulated stress responses.

POTS complicates matters further by adding issues such as rapid heart rate, dizziness, and fatigue on standing, making day-to-day activities increasingly difficult. Many individuals with POTS report feeling significant fatigue, especially in the mornings, with some improvement as the day progresses. However, the presence of post-exertional malaise—a hallmark of Long Covid—can limit even minor physical activities, further complicating recovery.

Diagnostic Tools: Understanding the Root Causes

Functional diagnostic testing is essential to understanding the root causes of Long Covid and POTS. By using a range of diagnostic tools, clinicians can uncover the underlying mechanisms driving the symptoms. Here are some of the most common tests that can shed light on the complex biology behind these conditions:

1. DUTCH Plus Test

This comprehensive hormone test provides valuable insight into the body’s stress response and adrenal health. Long Covid patients often experience what they describe as “adrenaline rushing through their body,” which points to dysregulation in the adrenal glands. The DUTCH (Dried Urine Test for Comprehensive Hormones) Plus Test evaluates cortisol rhythms, sex hormones, and their metabolites, helping clinicians understand how stress may be contributing to fatigue, sleep disturbances, and mood issues.

2. Chronic Lyme Disease Testing

Because many symptoms of Long Covid overlap with those of chronic Lyme disease—such as fatigue, neurological symptoms, and musculoskeletal pain—testing for co-infections is becoming an important aspect of patient care. In some cases, individuals may unknowingly carry tick-borne infections like Bartonella or Babesia, which can exacerbate Long Covid symptoms. Quick and affordable diagnostic tools can help detect these infections, allowing for targeted treatment.

3. Comprehensive Thyroid Panel

Thyroid function plays a critical role in energy metabolism and overall wellbeing. Subclinical thyroid dysfunction, often missed in routine tests, can contribute to fatigue and metabolic slowdowns seen in Long Covid patients. A full thyroid panel, including markers such as reverse T3, thyroglobulin antibodies, and TPO antibodies, can provide a more in-depth understanding of thyroid health and guide more specific treatment options.

4. Attomarker and Its Role in Long COVID and Immune Profiling

Attomarker’s COVID-19 Antibody Immunity Test provides a comprehensive analysis of antibodies (IgG, IgM, and IgA) specific to various SARS-CoV-2 proteins, including Spike 1, Spike 2, and Nucleocapsid. This test can help determine the strength, quality, and duration of immunity following infection or vaccination. It is a valuable tool for:
  • Assessing Immunity: Understanding whether an individual’s antibody levels are sufficient to provide protection from reinfection.
  • Vaccine or Infection Differentiation: Distinguishing between antibodies generated from infection versus vaccination.
  • Guiding Clinical Decisions: Helping patients and practitioners decide on further preventative measures such as boosters or other interventions.

Application in Long COVID

While the Attomarker test itself does not directly confirm persistent viral presence, it can provide a snapshot of immune activity that may hint at ongoing immune responses or dysregulation. For long COVID management:
  • Antibody Profiles: The test measures the antibody response to past infections or vaccinations, which may help clarify immune activation patterns linked to symptoms.
  • Clinical Insights: Elevated immune markers might suggest further investigation into co-infections or prolonged immune activation.

Treatment Options: Addressing the Underlying Mechanisms

Once a comprehensive diagnostic picture is formed, treatment can begin. In the functional medicine approach, the goal is not only to relieve symptoms but to restore balance to the body’s underlying systems. Here are some of the key treatments that have been found helpful:

1. Glutathione Complex

Many patients with Long Covid experience mitochondrial dysfunction, where their cells struggle to produce adequate energy. One potential remedy is Glutathione, a powerful antioxidant that supports mitochondrial function and reduces oxidative stress. Nutri Glutathione Complex, in particular, is used to boost energy production, supporting recovery from chronic fatigue and POTS.

2. Vitamin D Supplementation

Vitamin D plays a crucial role in immune regulation and inflammation control. Many Long Covid patients have suboptimal Vitamin D levels. Increasing the dose to 5000 IU/day for a month can help to bolster the immune system and improve symptoms like fatigue and muscle weakness. After an initial boost, patients can return to a lower maintenance dose.

3. Low-Dose Naltrexone (LDN)

LDN is gaining popularity for its ability to reduce inflammation and modulate the immune system in cases of chronic illness. Though not every patient will need LDN, it can be a game-changer for those suffering from persistent inflammation or immune dysregulation, making it a strong candidate for managing post-viral fatigue syndromes like Long Covid.

4. Pravastatin for Vascular Support

For patients experiencing vascular issues related to POTS, such as small vessel problems or peripheral shutdown, low-dose Pravastatin (10mg) can be used to support endothelial function and reduce inflammation. This is particularly helpful for individuals experiencing autonomic dysfunction alongside other cardiovascular symptoms.

5. Natural Anti-Inflammatories

In cases where patients prefer to avoid pharmaceutical options, natural anti-inflammatories like resveratrol, berberine, and grape seed extract offer promising alternatives. These nutraceuticals have demonstrated cardiovascular and anti-inflammatory benefits, making them valuable tools in the management of conditions such as Long COVID and POTS:
  • Resveratrol: Known for its antioxidant properties, resveratrol supports endothelial function, reduces oxidative stress, and helps modulate inflammation. It may improve circulation and protect cardiovascular health.
  • Berberine: This potent plant alkaloid has been shown to reduce systemic inflammation, improve blood sugar regulation, and support healthy cholesterol levels. Its impact on cardiovascular health makes it a potential ally in reducing the vascular inflammation often seen in Long COVID.
  • Grape Seed Extract: Rich in proanthocyanidins, this extract has strong antioxidant properties, helping to improve vascular health, reduce oxidative stress, and combat inflammation.
When used under professional guidance, these supplements can complement broader treatment plans, targeting the root causes of symptoms while minimizing reliance on pharmaceuticals. However, as with any intervention, it’s crucial to ensure they are appropriate for the individual, considering potential interactions or contraindications.
 

A Tailored Approach: Individualised Care for Complex Conditions

Every case of Long Covid and POTS is unique, requiring a tailored approach that addresses the specific imbalances in each patient’s body. By combining advanced diagnostics with evidence-based treatments, functional medicine offers hope for those struggling with persistent symptoms long after their initial Covid infection.

This approach focuses not only on addressing the symptoms but also on restoring cellular health, reducing inflammation, and boosting the body’s natural healing mechanisms. While recovery may take time, personalised care that digs into the root causes can provide meaningful improvements and help patients regain their quality of life.

For those suffering from Long Covid or POTS, it’s essential to work with a healthcare provider who is committed to understanding the multifaceted nature of these conditions and is equipped to offer holistic, functional treatment strategies. The road to recovery may be long, but with the right guidance, there is a path forward.
