Could Chronic Fatigue Syndrome be linked to the stress response?

By Russell Stubbs

How does ME/CFS start?

There are a number of different factors in the development of Fatigue related conditions. Viruses, bacterial infections, operations, vaccinations, etc. can all be triggers. This can lead to the development of Post Viral Fatigue Syndrome (PVFS), Chronic Fatigue Syndrome (CFS), Myalgic Encephalomyelitis (ME) and Fibromyalgia (FM). The cause can also be attributed to a stressful incident or time in a persons life. The common factor in all of theses cases is that the sufferer's system is under stress.

What happens when we are under stress?

We produce a powerful cocktail of chemicals - including cortisol, adrenalin and noradrenalin as a result of entering this state. This is the same chemistry produced during the fight or flight response - a natural process that is triggered in reaction to a perceived or real threat.

Many physiological changes occur during fight or flight

The sympathetic nervous system is responsible for a number of changes taking place. Heart rate and blood pressure increase in order to supply additional fuel to the major muscles. Blood sugar and thyroid levels are affected. Nonessential functions including digestion and immune system shut down allowing more energy for emergency systems.

Where's the connection between the stress response and Chronic Fatigue Syndrome?

The initial virus, bug, trauma, vaccination etc. has already under put the system under stress. If there were other stressors present or the person was run-down at the time, the recovery period could be prolonged. If the recovery is slow this can be a cause for concern, which results in more stress. The immune system, which is already challenged becomes depleted, further slowing the process of recovery.

Sufferers Search for Help

Sufferers typically seek help from their doctors who run tests for other ailments. The test results are negative but the symptoms persist. Sufferers often try alternative approaches. Sometimes these give temporary relief, but once again the symptoms return. People can easily lose trust in their body and energy levels. This further entrenches the stress - symptom - stress pattern.

Stress response over the long-term

When subjected to the stress response over the long-term the system becomes depleted. The chemistry that we produce in order to help us out of danger becomes toxic, depleting the immune system and disrupting most other bodily systems. Prolonged activation can cause adrenalin levels to become depleted. This dysregulation of stress chemistry causes more fatigue and physical symptoms.

Can it be all in the mind?

Chronic Fatigue Syndrome is clearly not all in the mind. It's an illness that is very physical in nature. It is known to affect most bodily systems. Approaches to recovery that are purely physical or that focus only on specific symptoms rarely work well. What's needed is an understanding of the mechanisms that trigger these physiological responses. We need to recognize that these mechanisms are very much a part of the mind. Until these patterns are addressed, full recovery over the long term is unlikely.

How can these cycles be broken?

Given the right tools it is possible to break free of these cycles relatively quickly. Recovery time, fortunately, is not relative to the duration of the illness. What's needed is an insight into the damaging unconscious cycles, along with an understanding of the mind - body connection. New physical and cognitive strategies can then be introduced in order to influence the health in a positive way.

You are not broken!

Sufferers of fatigue related conditions can typically feel broken or flawed in some way. Although the physical symptoms can be so severe that it feels as if this is so, this is not the case. Human health is incredibly buoyant, it is just necessary to discover what is in the way. Once we can bring balance to the system, we can create the opportunity for energy to return and physical symptoms to naturally resolve.
