Is There a Test to Diagnose Chronic Fatigue Syndrome?
Feeling tired all the time is called fatigue or exhaustion, which is when tiredness is overwhelming and is not relieved with rest. Tiredness is usually able to be alleviated with rest.
Chronic fatigue syndrome (CFS), also called systemic exertion intolerance disease (SEID) and previously called chronic fatigue immune dysfunction syndrome (CFIDS), is different from tiredness in that it is a chronic disorder characterized by several debilitating symptoms including severe fatigue.
It may be difficult to know if you’ve got chronic fatigue as the symptoms of CFS/SEID are similar to a number of other conditions, many of which go away on their own. It is important to see a doctor for a diagnosis to find out what is causing your symptoms.
There is no specific test for CFS/SEID. It is diagnosed through exclusion, that is, ruling out other illnesses with similar symptoms, such as:
- Thyroid conditions
- Mononucleosis (“mono”)
- Lyme disease
- Multiple sclerosis
- Certain cancers
- Vitamin D deficiency
- Bipolar disorder
