Long COVID and Chronic Fatigue Syndrome (CFS)

What are Long COVID and Chronic Fatigue Syndrome?

Long COVID and Chronic Fatigue Syndrome (CFS) are complex conditions characterized by persistent fatigue, muscle weakness, and a range of symptoms that significantly impact daily functioning. Long COVID symptoms develop following infection with the COVID-19 virus, whereas CFS may arise from various causes.

Common symptoms

• Severe fatigue and exhaustion
• Muscle weakness
• Disrupted energy regulation
• Reduced lung capacity
• Impaired circulation
• Cognitive difficulties (brain fog)
• Pain
• POTS (Postural Orthostatic Tachycardia Syndrome): rapid heartbeat on standing, dizziness
• PEM (Post-Exertional Malaise): symptom worsening after physical or mental exertion

Condition overview

Both conditions profoundly affect quality of life, often limiting work, social engagement, and daily activities. Disturbed circulation, nerve inflammation, and immune dysregulation contribute to symptom persistence. Specific challenges such as POTS and PEM can complicate recovery. POTS involves autonomic nervous system dysfunction causing dizziness and fatigue, while PEM refers to symptom flare-ups following exertion.

Causes

CFS can develop following viral or bacterial infections, or physical/psychological trauma. In Long COVID, the SARS-CoV-2 virus causes endothelial damage —the lining of blood vessels— leading to inflammation and impaired oxygen exchange in the lungs and tissues. This results in prolonged fatigue, poor circulation, and disrupted energy metabolism. Recent research (Amsterdam UMC) highlights mitochondrial dysfunction in muscle cells as a contributing factor to fatigue.

Why Quadrivas Therapy is Beneficial for Long COVID and CFS

Quadrivas Therapy offers a targeted, non-invasive approach focusing on vascular health — a crucial aspect given the role of endothelial cells. Through deep, manual techniques, the therapy enhances blood flow and vascular function.

Key therapeutic effects include:

1. Endothelial repair: Supporting the recovery and flexibility of blood vessel linings to improve circulation and oxygen delivery.
2. Enhanced oxygen transport: Stimulating blood flow to increase oxygen and nutrient delivery to organs and muscles, alleviating fatigue and aiding tissue repair.
3. Inflammation reduction: Helping to decrease low-grade inflammation, a known factor in Long COVID and CFS.

Outcomes and benefits

Clients frequently report:

• Increased energy levels
• Improved mental clarity
• Reduced pain
• Better vascular responsiveness to the body’s oxygen and energy demands

Quadrivas Therapy works across all tissue layers —from skin to bone— supporting circulation, waste removal, and nutrient supply. Healthy blood vessels are essential for recovery, and Quadrivas Therapy provides a strong stimulus to enhance vascular function and overall healing.
