Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and long COVID share many symptoms, including extreme fatigue, brain fog, and post-exertional malaise (PEM). But how are they connected? Could long COVID actually be a form of ME/CFS?

In this blog, we’ll explore the similarities between ME/CFS and long COVID, what research is saying, and what this connection could mean for treatment and recovery.

1. Similar Symptoms Between ME/CFS and Long COVID

Many people with long COVID experience symptoms that closely resemble ME/CFS, including:

• Severe fatigue that doesn’t improve with rest
• Brain fog and difficulty concentrating
• Muscle and joint pain
• Post-exertional malaise (PEM), where symptoms worsen after activity

Because of these overlapping symptoms, some researchers believe that long COVID may be triggering the same biological processes as ME/CFS. If you’re struggling with post-viral fatigue, this video on energy recovery offers helpful tips.

2. The Role of Viral Infections in Both Conditions

Both ME/CFS and long COVID often develop after a viral infection. Many people with ME/CFS trace their symptoms back to viruses like Epstein-Barr virus (EBV), influenza, or other post-viral illnesses. Similarly, long COVID occurs after a SARS-CoV-2 (COVID-19) infection.

Scientists believe that in some cases, the immune system overreacts to an infection and stays stuck in a chronic inflammatory state, leading to ongoing fatigue and other symptoms. To learn more about how viral infections affect recovery, watch this video on post-viral healing.

3. Post-Exertional Malaise (PEM): A Key Link

One of the strongest connections between ME/CFS and long COVID is post-exertional malaise (PEM). This is a worsening of symptoms after physical, mental, or emotional exertion, even from simple activities like taking a short walk or concentrating on a task.

PEM is unique to ME/CFS and long COVID, making it a critical clue that these conditions may be connected. Understanding pacing techniques can help prevent PEM and support gradual recovery. This video on pacing explains how to manage activity levels safely.

4. Nervous System and Autoimmune Similarities

Both conditions seem to involve nervous system dysfunction and possible immune dysregulation. Some studies suggest that in both ME/CFS and long COVID:

• The autonomic nervous system is disrupted, leading to issues like dizziness, heart palpitations, and temperature regulation problems.
• The immune system stays overactive, causing ongoing inflammation.
• The mitochondria (energy-producing parts of cells) may not function properly, leading to extreme fatigue.

5. What This Connection Means for Treatment & Research

Because long COVID is affecting millions of people worldwide, it has sparked more research into post-viral illnesses like ME/CFS. This is good news for both communities, as scientists are now:

• Exploring potential treatments that target immune and nervous system dysfunction.
• Identifying biomarkers that could lead to better diagnostic tools for ME/CFS and long COVID.
• Testing medications and therapies that may help with energy production and inflammation reduction.

While there’s still no universal cure, this new research is leading to more recognition and funding for both conditions. If you want to stay hopeful during recovery, this video on progress and healing may be helpful.

Final Thoughts

ME/CFS and long COVID share many similarities, from post-viral triggers to nervous system dysfunction and post-exertional malaise. This connection is finally bringing more attention to conditions that have long been misunderstood.

If you’re dealing with ME/CFS or long COVID, you’re not alone. With the right pacing, self-care strategies, and medical support, progress is possible. For more resources on managing symptoms and supporting recovery, visit the Solutions section of our website.
