Chronic fatigue syndrome (CFS), is a disorder characterized by profound fatigue that does not improve with bed rest and which be worsened by physical or mental activity.

CFS, is a complex debilitating disorder which results in people often functioning at a  lower level of activity than they were capable of before they became ill.

Researchers have not yet identified a clear cause of CFS.

CFS may be caused by a combination of factors which include

• Viral infections.Some people develop chronic fatigue syndrome after having a viral infection,
• Immune system problems. The immune systems of people CFS have been shown to be slightly impaired.
• Hormonal imbalances. Some people with CFS have been shown to experience abnormal blood levels of hormones produced in the hypothalamus, pituitary gland or adrenal glands in response to stress
• Nutritional deficiency

Because many illnesses have fatigue as a symptom, we  need to  rule out other conditions, which may be treatable.

These may include:

• Sleep disorders. Chronic fatigue can be caused by sleep disorders such as obstructive sleep apnea, restless leg syndrome or insomnia which can be indentified by a sleep study.
• Medical problems. Fatigue is a common symptom in several medical conditions, such as anemia, diabetes and underactive thyroid (hypothyroidism). Lab tests can check your blood for evidence of some of the top suspects.
• Mental health issues. Fatigue is also a symptom of a variety of mental health problems, such as depression, anxiety, bipolar disorder and schizophrenia. A psychiatrist can help determine if one of these problems is causing your fatigue.

Treatment of  CFS can be  complex. There are no specific medicines for treatment is CFS especially as symptoms can vary a lot over time. Close monitoring and treatment of symptoms with strategies that change as the pattern of the disorder pattern changes.

A team approach that involves doctors and patients is one key to managing CFS. Patients benefit when they can work in collaboration with a team of doctors who might include a psychiatrist, a rehabilitation specialist, and physical or exercise therapists. Together, they can create an individualized treatment program that best meets the needs of the patient with CFS. This program should be based on a combination of therapies that address symptoms, coping techniques, and managing normal daily activities.
