What is ME/CFS?

Myalgic Encephalomyelitis / Chronic Fatigue Syndrome (ME/CFS) is a complex, chronic condition characterized by severe fatigue that is not improved by rest and worsens with physical or mental activity. It affects multiple body systems, including the nervous system, immune system, and energy metabolism.

 

What are the main symptoms of ME/CFS?

Common symptoms include:

• severe, persistent fatigue

• post-exertional malaise (symptom worsening after activity)

• unrefreshing sleep

• brain fog or cognitive difficulty

• dizziness or orthostatic intolerance

• muscle or joint pain

Symptoms can fluctuate and vary in severity.

 

What is post-exertional malaise (PEM)?

Post-exertional malaise is a worsening of symptoms after physical, mental, or emotional exertion. Symptoms may increase hours or even days after activity and can last for several days or longer. PEM is considered a hallmark feature of ME/CFS.

 

What causes ME/CFS?

The exact cause of ME/CFS is not fully understood. Researchers believe it may involve a combination of factors such as immune system dysfunction, viral infections, nervous system changes, and abnormalities in how the body produces and uses energy.

 

Is ME/CFS the same as chronic fatigue?

No. While fatigue is a major symptom, ME/CFS is more complex than general tiredness. It involves a combination of neurological, immune, and metabolic symptoms that significantly affect daily functioning.

 

Can physical therapy help people with ME/CFS?

Physical therapy can help some individuals by focusing on pacing strategies, gentle movement, circulation support, and maintaining joint mobility. Therapy must be carefully adapted to avoid triggering post-exertional malaise.

 

Why does exercise sometimes make ME/CFS symptoms worse?

Many people with ME/CFS experience post-exertional malaise, meaning even small amounts of activity can trigger symptom flare-ups. Because of this, activity management and pacing strategies are essential when introducing movement or exercise.

 

Is ME/CFS related to dysautonomia or POTS?

Many individuals with ME/CFS experience autonomic nervous system symptoms such as dizziness, rapid heart rate when standing, or orthostatic intolerance. These symptoms overlap with conditions like POTS and other forms of dysautonomia.

 

Can people improve with ME/CFS?

Some individuals experience improvement in symptoms with supportive care, pacing strategies, and management of associated conditions. While recovery varies, many people learn strategies to better manage symptoms and improve quality of life.
