ME/CFS (chronic fatigue syndrome): more than being tired

The fatigue in ME/CFS is severe and is not caused by an unusually hard activity. Rest does not relieve it. It also comes with a real drop in how much a person can do compared with before.

People with ME/CFS get worse after any kind of activity, physical or mental. This is called post-exertional malaise (PEM), or a “crash”. It can bring trouble thinking, poor sleep, a sore throat, headaches, dizziness or severe tiredness. Recovering can take days, weeks or longer.

Many people with ME/CFS wake up feeling as tired as when they went to bed. Some also have trouble falling or staying asleep.

Most people with ME/CFS have trouble thinking quickly, remembering things and paying attention to details. Many describe it as feeling stuck in a fog.

Many people with ME/CFS feel worse when they stand or sit upright. This can bring lightheadedness, dizziness, weakness, fainting or blurry vision.

People may also have

• Chills and night sweats
• Digestive problems
• Frequent sore throat or tender lymph nodes
• Headaches, and muscle or joint pain
• Muscle weakness or shortness of breath
• Sensitivity to food, smells, chemicals, light or noise

In 2021–2022, 1.7% of U.S. women and 0.9% of U.S. men had ME/CFS.

In 2021–2022, about 0.7% of adults aged 18–39 had ME/CFS, rising to about 2% of adults in their 50s and 60s.

In 2021–2022, 2.0% of adults in families below the poverty line had ME/CFS, compared with 1.1% in families with higher incomes.

The illness also makes it hard to keep working, which can push money worries even higher.

White people are diagnosed with ME/CFS more often than other groups. The CDC notes that many people from racial and ethnic minority groups have ME/CFS but have not been diagnosed.

Some people keep working or going to school, often by cutting back on everything else. Evenings and weekends may be spent resting just to get through the next week.

Severely affected people may be house-bound for periods of time and need special care.

What can help

• Home visits or telehealth appointments where possible
• Online friends and support groups
• People who can run errands for you
• Short phone or text check-ins instead of visits

At its most severe, ME/CFS can mean being in bed for long stretches and needing special care. Many people with ME/CFS are also sensitive to light and noise.

Symptoms may come and go, and their strength can change over time. Some people have better seasons and harder seasons.

Things worth noting

• How you feel 1–2 days after a busy day
• How your sleep feels in the morning
• Thinking and memory problems
• What you’ve had to give up or cut back
• What happens when you stand or sit up for a while

Clinicians look at how symptoms affect your life. Concrete examples help: “I used to work full time. Now a 20-minute shop means I’m in bed the next day.”

You could say

• “After I do something, I crash a day or two later.”
• “Resting doesn’t make the tiredness go away.”
• “This has been going on for more than six months.”

Researchers who studied people dismissed by clinicians suggest bringing a supportive person to appointments. They can help describe your symptoms and remember what was said.

Things you can ask

• “Could ME/CFS be part of this?”
• “Could you note in my record that we discussed this?”
• “What else could we look at?”
• “Is there a specialist who knows this illness?”

Many people grieve their old job, hobbies, friendships and plans. This grief can come back in waves, for example on birthdays or when friends share news.

Because activity can make you worse a day or two later, it’s easy to feel on edge about every choice. Some people start to fear plans, visits or even phone calls.

ME/CFS often makes it hard to take part in family and social life. Over time, invitations can stop and friendships can fade.

Small ways to stay connected

• Online communities for people with ME/CFS
• Short voice notes instead of long calls
• Telling one or two people exactly what kind of contact you can manage
• Watching a show “together” by message

People who are not believed often start to doubt themselves and feel ashamed. They may play down their symptoms so they don’t seem dramatic.

You could say

• “It’s a long-term illness that affects my whole body. Doing too much makes me sick for days.”
• “It’s not tiredness. It’s like having the flu and a hangover that rest doesn’t fix.”
• “I may look fine right now. You’re seeing me on the part of the day I saved up for.”

Common ones

• “Have you tried pushing through?”
• “I get tired too.”
• “It must be nice to rest all day.”
• “You just need to exercise more.”
• “You looked fine yesterday.”

Standard exercise advice for healthy people can actually be harmful for people with ME/CFS, so “just push through” is not good advice.

Explaining takes energy you may not have. It’s okay to give a short answer, change the subject or step back from people who keep dismissing you.

Activity management, or pacing, means finding your own limits for physical and mental activity and planning so you stay within them.

The CDC says people with ME/CFS do not tolerate vigorous aerobic exercise, and standard exercise advice for healthy people can be harmful. In the UK, the NHS says graded exercise therapy, which steadily increases activity, is not recommended for ME/CFS.

Talking therapy such as CBT can help people cope with living with ME/CFS. The NHS is clear that it does not directly treat ME/CFS symptoms, and that the therapist should have experience with the illness.

Questions to ask a therapist

• “Have you worked with people with ME/CFS before?”
• “Can we do sessions by video or phone on bad days?”
• “Do you understand that pushing harder can make me worse?”

Deep breathing, muscle relaxation, massage and gentle movement such as stretching may help some people with stress and anxiety. Choose only what fits within your energy limits.

Equipment like a wheelchair or a stairlift can make daily living easier, and some people are eligible for help with care at home.

Try

• “I believe you.”
• “No need to reply. Just thinking of you.”
• “Would a short visit or a text be better this week?”
• “You can cancel any time, no explaining needed.”

Avoid

• Comparing it to your own tiredness
• Pushing them to “just try” more activity
• Saying they look fine
• Sending cures you saw online

Being discounted by family and partners is linked with more distress for people with long-term symptoms.

Ideas

• Cook and freeze a few meals
• Drive them to appointments and take notes
• Help with forms and phone calls
• Pick up groceries
• Visit quietly and keep it short

Supporting someone with a long-term illness can bring stress, worry and money strain. Your feelings are valid, and you deserve support too.

The Solve ME/CFS Initiative (Solve M.E.) funds research and advocacy for ME/CFS, long COVID and related illnesses. Its website has resources for patients and caregivers, tips on finding a doctor, patient stories and research news.

Online support groups let people connect without the energy cost of travel. Look for groups that are moderated, kind and focused on living well rather than selling cures.

Signs of a healthy group

• Clear rules about kindness
• Moderators who remove unsafe advice
• No pressure to buy products
• Room for both good and bad days

Some people find meaning in sharing their experience, for example through patient story projects or research registries. Only share what feels safe and only when you have the energy.
