Researcher have threes and are investigating a variety of possibilities. Some believe that CFS is due to a combination of viruses, allergies, and hormonal imbalances. Studies also suggest that it could be due to a dysfunction of the immune system. However current theory holds that CFS may develop when an opportunistic virus or other agent invades the body at a time when the immune system is already suppressed. Factors that could contribute to this would be physical, emotional, or environmental stress, or a combination of the three.
Some people are skeptical about chronic fatigue syndrome however.
Some believe that CFS is a psychological disorder rather than a physical one. Treatment for chronic fatigue syndrome is restricted to relief symptoms. Because the cause of CFS is unknown, it is very difficult to treat. There are a number of conventional and alternative therapies that can help through the course of the disease. Maintaining general good health while avoiding situations that are physically or psychologically stressful and to balance rest and onvigorous exercise is a good beginning.
