Chronic fatigue syndrome and post-viral fatigue: where to start

CHRONIC FATIGUE · 9 MIN READ

ME/CFS is not ordinary tiredness, and rest alone does not resolve it. Understanding post-exertional malaise is the first step to recovering without repeated crashes.

In short

• The defining feature of ME/CFS is post-exertional malaise: a crash after effort that once would have been easy.

• Pushing through or graded exercise can make it worse. Pacing is the foundation.

• Recovery means finding what keeps the body in protection, then rebuilding gradually.

Chronic fatigue syndrome, also called myalgic encephalomyelitis or ME/CFS, is one of the most misunderstood conditions in medicine. It is not ordinary tiredness, and it is not a lack of motivation. It is a complex illness that affects energy production, the nervous system and the immune system, and it can change a person's whole life.

Many cases begin after a viral infection, including glandular fever and COVID-19. Others follow a period of severe stress, an injury or an accumulation of things the body could not recover from.

What is post-exertional malaise?

The defining feature of ME/CFS is post-exertional malaise. After physical, mental or emotional effort that would once have been easy, symptoms worsen, often a day or two later, and can take days or weeks to settle. People describe it as a crash.

This is what separates ME/CFS from other kinds of fatigue, and it is why the usual advice to push through, exercise more or build up gradually can make it worse. Current international guidance, including from the UK's National Institute for Health and Care Excellence, no longer recommends graded exercise therapy for ME/CFS for this reason.

Other common symptoms

• unrefreshing sleep, however long you sleep

• brain fog, slowed thinking and difficulty finding words

• dizziness or a racing heart when standing

• muscle and joint pain, headaches

• sensitivity to light, sound, food or chemicals

• sore throat and tender glands that come and go

Why rest is not enough

In ME/CFS, the body's energy system appears to be stuck in a protective state. Research into the Cell Danger Response describes how cells shift from producing energy to defending themselves when they sense threat. When that signal does not switch off, energy production stays low, and every demand draws on reserves that are already depleted.

Rest is essential, but on its own it does not switch the signal off. What is keeping the body in protection also needs to be found and addressed.

Pacing: the foundation

Pacing means staying within your available energy, your energy envelope, so that you stop crashing. It sounds simple and is one of the hardest things to do, especially for people used to being capable and busy.

• Learn your early warning signs and stop before them, not after.

• Break tasks into small pieces with rest in between.

• Count mental and emotional effort, not only physical.

• Keep a simple record of activity and symptoms to find your baseline.

• Expand slowly, only when the baseline has held steady for some time.

What else helps

Safety first. Nervous system regulation, so the body is no longer braced against the next demand.

Nourishment. Steady meals, enough protein and minerals, and attention to blood sugar.

Mitochondria. Gentle support for cellular energy once the body is stable enough to use it.

The underlying load. Looking for what may still be driving the illness: unresolved infection, mould exposure, gut issues, hormonal or thyroid patterns.

Circulation. Fluids, salt where appropriate and medical assessment if you feel dizzy or your heart races on standing.

How I work with chronic fatigue and ME/CFS in clinic

I start by finding your current energy envelope and helping you stop crashing. I read your bloods through Endobiogeny and look for what may still be driving the illness: infection, mould, the gut, hormones or thyroid.

Herbal and nutritional support is compounded and introduced slowly, because a depleted system needs gentle steps, never a push.

Frequently asked questions

What is the difference between chronic fatigue and ME/CFS? Many conditions cause chronic fatigue. ME/CFS is a specific illness defined by post-exertional malaise, unrefreshing sleep and cognitive symptoms.

Is exercise good for ME/CFS? Pushing exercise can trigger crashes. Current international guidance no longer recommends graded exercise therapy. Pacing within your energy envelope comes first.

Can you recover from post-viral fatigue? Many people improve substantially, usually gradually. Pacing, nervous system support and addressing the underlying load give the best foundation.

Where to start

Recovery from ME/CFS is usually gradual, and it is possible to make real progress without being pushed past your limits. In an initial consultation, we map your history, triggers and current capacity together, and set a pace your body can sustain. For people who need regular support, the Chronic Fatigue, ME/CFS and Fibromyalgia pathway of The Deep Reset offers twelve consultations alongside the foundations of healing.
