Up to 91% of people with ME/CFS (myalgic encephalomyelitis / chronic fatigue syndrome) have not been diagnosed. These people are not receiving appropriate treatments or healthcare advice. If you feel tired often, how would you know if you have this disease?

What are the symptoms of ME/CFS?
Myalgic encephalomyelitis, also known as “chronic fatigue syndrome,” or “ME/CFS,” or even a proposed new label, “systemic exertion intolerance disease,” includes:
- DEBILITATING FATIGUE THAT IS CONSTANT OR RECURRING
- This is not tired because you’ve had a long day. It’s fatigue like you have the flu or like you are on chemotherapy. Some patients describe this as feeling like they have lead or concrete in their body or that they have no energy, like a dead battery.
- NON-RESTORING SLEEP
- Waking up feeling drained or like you have a hangover. Most of these patients take more time (up to two hours) to transition from sleeping to awake activity. They may have insomnia or require more than eight hours of sleep, yet still not feel fresh in the mornings.
- TROUBLE WITH THINKING ABILITIES
- This could include the inability to process new information quickly (such as when given driving directions or asked to remember a phone number). It could include the inability to do math in your head or difficulty multitasking. Forgetting words or getting your “wires crossed” is also commonly reported in those with ME/CFS.
- ORTHOSTATIC INTOLERANCE
- The patient feels a strong urge to lie down or they may feel dizzy. Often patients unconsciously compensate by folding their legs when they sit down or shifting their weight from one leg to another when they stand. They may not know why, but they avoid lines, doing dishes at a sink, or standing at a sink to brush their teeth. Standing in a hot shower exacerbates this feature of the disease.
- OTHER SYMPTOMS
- Some patients experience include muscle pain, sore throats, swollen lymph nodes, sound and light sensitivity, cold or heat sensitivity, headaches, easy bruising, and vertigo. In all, about 60 different symptoms can occur with the disease, and each patient’s symptom profile may be different.1
ME/CFS and children
The presentation and course of the disease is often different in children. Dr. David S. Bell, a member of our ME/CFS Scientific Advisory Board, provided us an in-depth description of pediatric ME/CFS.
How can ME/CFS be distinguished from other similar diseases?
One symptom or timing of symptoms has been described as the distinguishing hallmark of the disease. Referred to as “post-exertional malaise,” ME/CFS patients with mild or moderate cases may have brief periods without noticeable fatigue or other symptoms. But it doesn’t last long. Then within hours or a few days of the activity, the patient experiences a “crash” of feeling sick, so sick they can’t function.2,3 It may last hours, days, or weeks. Depending on how bad the episode is, the “crash” symptoms may include hoarse voice, debilitating fatigue, mental fog, body aches, headache, hot and cold flashes, nausea, and vomiting.
In these cases, some patients find they can start off at work feeling pretty good on Monday because they rested over the weekend. Then they find that by Tuesday afternoon or Wednesday, they are struggling to finish the work day. In addition to mental or physical activity, other triggers for a “crash” include infections, surgery, an accident, or stress.
Severe cases, about 25 percent of the estimated 1 million Americans with the disease, struggle to take care of their daily needs, such as changing clothes and preparing a meal.4 And some of those are totally bed-bound and too weak to feed themselves or even talk.
Autism Spectrum Disorder is not ME/CFS but some strong similarities exist. Learn more.
How does it start?
The disease can be triggered by an infection or series of infections, surgery, another illness, an accident, or any other physical or emotional stressor. It may come on gradually or suddenly. Commonly, people with the disease say they feel they caught a flu, but it never went away. Some report the symptoms starting one day without any apparent trigger. ME/CFS seems to have a genetic component because it occurs more often among blood relatives.
What should I do if I think I might have ME/CFS?
If you suspect you have this disease, you will want to discuss this with your doctor who will want to rule out another illness that has some of the same symptoms, such as fibromyalgia, hypothyroidism, cardiac dysfunctions, an infection, or depression. Of course, it is possible a person could have one of these other conditions and also have ME/CFS. Women ages 35-50 are at a higher risk of coming down with this disease. The second most common group to develop it includes boys and girls in their adolescence (ages 11-23). However, it can strike anyone, including men and young children.

What causes the symptoms?
Research has revealed brain inflammation, systemic inflammation, low blood volume, immune system deficiency, abnormal gene reactions to exercise, abnormal energy metabolism in response to exercise, and abnormalities in the hypothalamic/adrenal/pituitary system. But none of these biological findings have led to a widely accepted diagnostic marker or led to an understanding of the cause of all the symptoms.
How is it treated?
Mental and physical activity pacing (limiting type and duration and including rest periods throughout), avoiding stressors, and using supplements or medications to gain some control of the symptoms are the only treatments available at this time. Counseling (sometimes erroneously referred to as “cognitive behavior therapy”) may help a person adjust to and effectively cope with the new limitations of the disease. The FDA has not approved any medicine that impacts the cause of the symptoms or alters the biological malfunctions of the disease.
Why should you support ME/CFS research?
For decades, ME/CFS has received very little research funding compared to other diseases, many not as severe or as common. This disease consumes much of the family resources and time, so patients and their families have not been able to orchestrate an organized and sustainable advocacy or lobbying effort to motivate more research funding. Yet, recent discoveries, as mentioned recently by OMF Scientific Advisory Board Director Ronald W. Davis, PhD. in his recent ME/CFS research update, show we are on the precipice of breaking open the mysteries and bringing validation and relief to those who currently suffer.
This is why research in ME/CFS is a priority for our organization, especially since discoveries in ME/CFS will most likely lead to a better understanding of the symptom mechanisms in similar chronic diseases, such as fibromyalgia, chronic Lyme disease, Gulf War illness, and multiple sclerosis.
The Open Medicine Foundation is focusing on funding research that will put an end to this disease and bring back vitality to the many people now suffering–benefitting them, their families, and society.
You can help us put an end to ME/CFS.
