Fatigue is a condition of exhaustion and lack of energy caused by several factors such as viral infection, overexertion and lack of sleep. As fatigue is a normal condition, most people have experienced fatigue at least once in their lifetimes. The feeling of exhaustion is usually relieved after the person gets some rest. But if a person suffers from fatigue for extended periods of time, usually more than 6 months, he/she may be suffering from chronic fatigue syndrome.

Chronic fatigue syndrome is a condition of extreme and persistent fatigue that lasts for six months and more. It usually comes with several other symptoms such as muscle pain, aches in the joints, sore throat, and lack of energy. Most people with chronic fatigue syndrome or CFS usually suffer from a more serious disorder like fibromyalgia, rheumatoid arthritis and chronic fatigue immunodeficiency syndrome. The exact cause of chronic fatigue syndrome is hard to determine, but it is widely believed that there are three factors that trigger this debilitating disorder.

The Causes of Chronic Fatigue Syndrome

• Viral or bacterial infection – Exposure to viruses and bacteria can cause chronic fatigue syndrome. The symptoms of fatigue usually disappear when the infection is successfully treated.

• Overexertion – Rigorous physical activities that go beyond what the body can take results to extreme exhaustion. Athletes who are prone to over training are susceptible to this.

• Depression – Some doctors believe there is a link between chronic fatigue syndrome and stress or anxiety. Peopl
