Knoxville (WVLT) - Long-doubted as a legitimate illness by doctors and employers, centers for disease control and prevention officials have released data suggesting Chronic Fatigue Syndrome is far more common than previously thought.
Chronic Fatigue Syndrome is defined as severe fatigue not relieved with rest, lasting six months or longer, and reducing a person's ability to do daily activities.
Studies indicate as many as one million Americans suffer from the disease.
But CDC officials say fewer than 20 percent of people with the illness have been diagnosed.
"It has no good lab test to really diagnose it, so if you can't absolutely diagnose it, know what it is to do it, treatment, it doesn't seem to respond to any specific type of treatment,” explains UT Medical Center pulmonologist Dr. Thomas Sullivan.
Recent scientific findings have linked CFS to abnormalities in the body's nervous system, which controls blood pressure, heart rate and other functions.
