Misunderstood illness leaves millions exhausted, with most cases undiagnosed
Chronic fatigue syndrome affects 3.3 million people in US, with one in four confined to bed at some point
The article explains that chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME), is a poorly understood condition affecting approximately 3.3 million people in the United States. Fatigue from many causes is common, but when severe exhaustion lasts for months, often after an infection, it may signal CFS. About one in four patients are confined to bed at some point, yet past research suggests only around 15% are correctly diagnosed.
CFS is defined by severe new-onset fatigue lasting at least six months that limits daily activities, worsening malaise after physical or mental exertion, and unrefreshing sleep. Patients may also experience brain fog or lightheadedness when standing. There are no definitive diagnostic tests, so doctors rely on patient history, examinations, and ruling out other conditions such as hypothyroidism or depression.
Experts describe CFS as an immune-related disorder, more common in women, with possible genetic links on the X chromosome. Triggers can include infections, chronic stress, nutritional deficiencies, hormone imbalances, sleep problems, trauma, pregnancy-related hormonal shifts, and sudden infections like COVID or mononucleosis. Treatment varies, focusing on symptom management through lifestyle changes, therapies, and medications, as no single therapy works for everyone.
