Doctor explains: How to explain ME/CFS to your relatives, friends and colleagues

If you live with ME/CFS, one of the hardest parts is often not just the symptoms themselves — it is trying to explain them to other people.

Many people with ME/CFS tell me the same thing: “People can’t understand me. I look normal, they think I just feel tired.” Unfortunately, tiredness is only a small part of the picture.

As an ME/CFS specialist, one of the most important things I discuss during consultations is how patients can explain their illness in a way that others can understand. Whether speaking to family, employers, friends or colleagues, having simple explanations can make difficult conversations easier.

The first thing to explain: ME/CFS is not ordinary tiredness

ME/CFS (Myalgic Encephalomyelitis / Chronic Fatigue Syndrome) is a complex medical condition affecting multiple body systems.

Many patients experience:

• Severe exhaustion that does not improve with rest

• Brain fog and concentration problems

• Muscle/joint pain and weakness

• Sleep problems

• Dizziness or feeling faint

• Sensitivity to light, sound or stimulation

• Gut symptoms

• Symptoms worsening after activity (called post-exertional malaise)

This is why many people seek specialist assessment, ME/CFS testing, ME/CFS therapy and ongoing support from an online ME/CFS doctor or post-viral fatigue doctor.

Analogy 1: “It feels like having the flu all the time”

This is often the easiest place to start.

You can say:

"Imagine having flu — the body aches, heavy limbs, exhaustion and difficulty thinking clearly. Now imagine feeling like that every day, for months or years."

Most people have experienced the flu before, so this analogy helps people understand that ME/CFS is much more than feeling sleepy or lacking motivation.

Many patients tell me this is the analogy relatives understand most quickly.

Analogy 2: “My battery does not hold a charge anymore”

Another useful explanation is the old phone battery analogy.

You might say:

"Remember an old phone where the battery used to last all day, but now drops from 80% to 10% very quickly? That is what my energy system feels like."

People without ME/CFS often assume energy works like a rechargeable battery:

• Sleep

• Recharge

• Wake up refreshed

For many people with ME/CFS, this does not happen.

Instead:

• Energy is limited

• Small activities drain it quickly

• Rest does not reliably restore it

• Overusing energy can worsen symptoms dramatically, and people can “shut down”

This analogy can help explain why pacing and activity management are important parts of ME/CFS therapy.

Analogy 3: “It is like driving with the handbrake permanently on”

This is one of my favourite explanations because it helps explain why simple activities feel difficult.

You might say:

"Imagine driving a car with the handbrake always partially on. The car still moves, but everything requires more effort and uses more fuel."

This explains why:

• Showering can feel exhausting

• Socialising may require recovery time

• Working becomes difficult

• Small tasks can trigger worsening symptoms

People often assume: “If you can do something once, you should always be able to do it.”

ME/CFS does not work like that.

Explaining post-exertional malaise (PEM)

One of the hardest concepts to explain is post-exertional malaise.

Many people say:

"But exercise helps fatigue, doesn’t it?"

For ME/CFS, activity can sometimes trigger delayed worsening.

You can explain it like this:

"Imagine your body has an energy limit. If I go beyond it today, I may pay for it tomorrow or even several days later."

This delayed worsening is one reason specialist assessment from an ME/CFS specialist can be important.

Increasing research into ME/CFS research and Long COVID fatigue clinic services has helped raise awareness of post-exertional symptom worsening.

Explaining invisible illness

Many people with ME/CFS look relatively well.

This can create a misunderstanding.

You could explain:

"You are seeing me during a small window of activity. You are not seeing the recovery afterwards."

Patients often tell me:

• Friends see a short social visit

• Colleagues see one meeting

• Family see one good day

What they do not see:

• The crash afterwards

• Days of recovery

• Increased symptoms

Invisible illnesses are difficult because appearance rarely reflects severity.

What relatives and colleagues can do that actually helps

Sometimes people want practical guidance.

You could tell them:

Helpful things:

• Believe me when I describe symptoms

• Avoid comparing it to normal tiredness

• Understand plans may change

• Allow flexibility

• Ask what support helps

Less helpful things:

• “Maybe you just need exercise”

• “Everyone gets tired”

• “You looked fine yesterday”

• “You need to push through”

Understanding usually improves relationships far more than trying to convince someone the illness exists.

Why this conversation matters

Explaining ME/CFS is emotionally exhausting.

Many patients feel they must repeatedly prove they are ill.

You do not need perfect explanations.

You only need explanations that people can understand.

Sometimes one simple analogy works better than ten medical terms.

As an online ME/CFS doctor, I often find that helping patients explain the condition to others can improve work discussions, family relationships and day-to-day support.

Whether someone is looking for an ME/CFS specialist, fibromyalgia specialist online services, support from a post-viral fatigue doctor, or assessment through a Long COVID fatigue clinic, a better understanding from others often makes a meaningful difference.
