Chronic Fatigue Syndrome: 8 Warning Symptoms To Look Out For
December 20, 2017 14:20
It’s normal to feel tired after strenuous physical exercise or difficult mental activities. But there’s a condition in which people feel extremely fatigued for no apparent reason. The condition is called chronic fatigue syndrome (CFS); its other names are myalgic encephalomyelitis (ME) and systemic exertion intolerance disorder (SEID).
Chronic fatigue syndrome is something of a mystery illness. To this day, its cause (or causes) remains unknown. Some experts suggest it may be related to fibromyalgia, another poorly understood disorder. It’s been only three decades since CFS was recognized as a legitimate medical disorder. Some doctors still call the very existence of CFS into question. But it’s gained more recognition, and extensive studies are being carried out to learn more about CFS.
