What is the prevalence of Chronic Fatigue Syndrome / M.E.?

How many people does Chronic Fatigue Syndrome / M.E. affect? Does it have the same prevalence in men and women? And in the different countries?


Chronic Fatigue Syndrome, also known as Myalgic Encephalomyelitis (CFS/ME), is a complex and debilitating condition characterized by extreme fatigue that cannot be explained by any underlying medical condition. The prevalence of CFS/ME varies across different populations and studies, making it challenging to determine an exact figure. However, it is estimated that approximately 0.2% to 2.5% of the global population may be affected by this condition.

CFS/ME can affect individuals of all ages, genders, and ethnicities, although it is more commonly reported in women. The condition often begins in early adulthood and can persist for many years, significantly impacting a person's quality of life. The exact cause of CFS/ME remains unknown, but it is believed to involve a combination of genetic, environmental, and immunological factors.

Diagnosis of CFS/ME can be challenging due to the absence of specific diagnostic tests. Healthcare professionals rely on a thorough evaluation of symptoms, medical history, and ruling out other potential causes of fatigue. Treatment for CFS/ME primarily focuses on managing symptoms and improving overall well-being through a multidisciplinary approach involving rest, pacing, cognitive-behavioral therapy, and symptom-specific medications.

It is important to raise awareness about CFS/ME to ensure timely diagnosis, appropriate support, and further research to better understand and address this debilitating condition.

0.2% of the population.

It is said that there are more female patients, but I think it is a case of gross mis-diagnosis & the disease impacts equally across class, gender, age. The figures range from 2-4 million in USA to 20 million globally, but again it could be way higher as doctors are not taught about viral epidemics or how to diagnose & treat them at med school (shocking). Travel is probably spreading the disease as well as zoonosis (contact with wild animal species).

ME/CFS is a devastating disease that disables up to 2.5 million people in the U.S.A. alone (20 million worldwide). Anyone can get it (all ages, races, ethnicities), often after a virus or flu-like illness. ME/CFS occurs more often in women than in men.

There is a rough estimate of 17 million peopole with ME-CFS worldwide. It affects more women than men, more adults than children. Children who get it have to deal with school issues. At whatever age it affects, it is almost always a lifelong sentence. It happens at any time, at any age.

Both are known to be present worldwide females have a much greater chance of being affected.

the numbers are unavailable as the epidemiology and patient tracing hasn't been done 5% is a good guess , but it could be higher ME does not care who it infects or what age you are or what gender or what color your skin is some populations go unreported for various reasons including lack of insurance and the fact that there is no bureau to report the disease to atm the CDC has made it unreportible as have the name changes

It affects more women than men, I think they are two-thirds women and one third men and women more or less. The affected, if I am not mistaken they are 4% or more of the population. The children also become ill, but not more than adults.
