Fatigue is generally defined as a feeling of lack of energy and motivation that can be physical, mental or both. Most of the time a physical cause has been estimated to be responsible for fatigue, though emotional or mental causes can also be the cause. Fatigue can also occur in normal individuals that experience intense physical or mental activity or both.
However in contrast to fatigue that occurs with some diseases and syndromes, normal fatigue in healthy individuals is relieved when the physical or mental activity is reduced. People occasionally experience fatigue after eating large meals.
If you’re getting your eight hours of sleep a night but still feel exhausted, it’s time to see a doctor. It’s also worth seeking medical advice if you have any of these symptoms: confusion; dizziness; blurred vision; unexplained weight loss or gain; swelling; constipation; insomnia; depression; headaches.
Chronic Fatigue Syndrome is characterized by extreme, debilitating fatigue that doesn't go away with rest, and lasts for six months or more, hindering normal, everyday activity. There is no cure.
After evaluating four potential treatments for the mysterious condition, British researchers concluded that a form of talk therapy, called cognitive behavioral therapy, and graded exercise therapy are among the best available treatments for extended relief.
"There is always hope for a simpler treatment in a pill, but we are not near that yet. So, at present treatments that work to rehabilitate patients toward normal activity remain the best ones," said Dr. Michael Sharpe, a study co-author and professor of psychological medicine at the University of Oxford in England.
