ME/CFS

Encephalomyelitis myalgica

DE FR EN

The exhaustion does not lift with rest and worsens after exertion — which is why pacing is central.

A serious, long-lasting illness with profound exhaustion that rest does not relieve. Its hallmark is post-exertional malaise (PEM): even small physical or mental effort can trigger a major crash hours or days later. ME/CFS is a recognised physical illness (ICD-10 G93.3) — not imagined, not laziness, not depression. Its causes are not fully understood; it often begins after an infection. There is no curative treatment, but managing one’s energy well can make a real difference.

Levers & pathways

studiedPacing / energy management

The most important lever: stay within your energy limits and avoid overexertion to prevent crashes.

studiedNo forced graded exercise

Pushing progressive exercise against the body can worsen ME/CFS — the goal is to adapt, not to push through.

associatedTargeted symptom relief

Sleep, pain and circulation can each be treated, even if the illness itself remains.

associatedUnderstanding & relief

Being taken seriously is a huge relief. Exchange with others affected and everyday accommodations help.

studiedNumbers and timeframes

Estimates run at two to four in a thousand people; women are affected more often. Several years pass on average before the diagnosis. The exertion intolerance typically shows only twelve to forty-eight hours afterwards — which is why it is missed for so long.

infoWhat the medicine does — and what it does not

There is no drug for the illness itself — what can be treated separately is treated: sleep, pain, circulation when upright, irritable bowel. The most important point is not a medicine but the limit of exertion: activity above one’s own threshold triggers a worsening that arrives hours to days later and lasts days to weeks. That is why a graded exercise programme does not mean the same thing here as in other states of exhaustion.

Possible complaints

studiedPost-exertional malaise (PEM)

The decisive feature: delayed, often overwhelming crash after exertion. Distinguishes ME/CFS from ordinary tiredness.

associatedUnrefreshing sleep

No recovery even after long sleep.

associatedConcentration & memory problems (brain fog)

Thinking as if through fog, word-finding and memory trouble.

associatedCirculatory problems when upright

Dizziness, palpitations or light-headedness on standing (orthostatic intolerance).

Blood values

studiedTSH (thyroid)

No value proves ME/CFS. These values look for the treatable explanations — the thyroid comes first among them.

studiedFerritin

An iron shortage explains exhaustion even without anaemia and is simple to correct.

studiedVitamin B12

Belongs to the basic workup of lasting tiredness, especially with a diet low in meat or long use of stomach medicines.

studiedtTG-IgA (coeliac disease)

Coeliac disease can show itself with tiredness almost alone. The value only holds while gluten is still being eaten.

Nutrients

studiedVitamin B12

A lack causes exhaustion, problems concentrating, low mood and forgetfulness — and it is one of the few causes that can be found and put right with a single blood draw.

associatedVitamin D

Low values are common with low mood. Whether correcting it lifts the mood is not settled; that it makes sense in winter at our latitudes is.

associatedVitamin B1 (thiamine)

The nerves cover their energy needs through thiamine. It runs short with alcohol, after stomach operations, with long-lasting vomiting and under water tablets.

studiedIron

An empty store causes tiredness, lack of drive and problems concentrating long before any anaemia becomes visible. In women of childbearing age the most common single reason.

associatedVitamin B6

Here both count: a lack harms the nerves, and too high an intake over months harms them as well. Supplements therefore belong taken in a dose that has a reason.

Supplements

mixedCoenzyme Q10 / ubiquinol

Studied in small trials together with NADH over 8–12 weeks, 200–300 mg a day. The reported differences are small, and none of these studies was large enough for a firm statement.

mixedD-ribose

An open study at 5 g three times a day over 3 weeks reported more energy — without a control group. That is the state of things: much reported experience, little comparison.

mixedVitamin B12

Often injected in ME/CFS. A real deficiency belongs found and replaced; beyond that no benefit is shown. Once the doses begin the blood value says nothing.

infoVitamin D3 (+K2)

Clearly worthwhile and well studied when deficient; fewer data for the wider uses. Fat-soluble — check blood levels at high doses.

infoIron

Clearly effective with proven deficiency, useless without. Take only with a documented deficiency — excess is harmful.

Hormones

associatedCortisol

No hormone finding proves ME/CFS. What is described is an on average flatter daily course of the stress axis — that is an observation across groups and is no test for the individual.

associatedAldosterone and renin

This axis holds salt and blood volume. It explains why salt and how much one drinks matter so much when upright, and why long standing worsens the complaints.

associatedNoradrenaline

Stands for the regulation of the circulation on standing up. A racing heart and light-headedness when upright are among the commonest companions and can be tackled specifically.

associatedMelatonin

The giver of the day-night rhythm. A shifted or reversed rhythm worsens everything else — which is why light in the morning counts for more than it sounds.

associatedT3 (thyroid hormone)

With any long-lasting exhaustion the thyroid is checked, because it makes the same picture and is treatable. A low T3 with a normal TSH is usually a consequence and not a cause.

Food

studiedSmall meals and salt with circulatory complaints

Many also have a POTS picture. Then 2–3 litres of fluid, more salt and smaller meals help — not with high blood pressure or kidney disease.

infoCooking costs energy

With exertion intolerance the preparing itself can trigger a crash. Pre-cooked food, frozen items and simple meals are not carelessness here but energy management.

Alternative approaches — what people use

studiedMindfulness & meditation

Studied as a way of living with the illness, not as a treatment of its cause — the difference matters to those affected.

traditionalCoenzyme Q10

Often taken together with other mitochondrial nutrients; the studies are small.

studiedVitamin B12

A deficiency causes the same complaints and is treatable — which is why it is measured.
