Chronic Fatigue Syndrome (CFS) is something most people have heard of, so some people might assume they have it if they feel tired all the time.
There seems to be an accepted definition of Chronic Fatigue Syndrome. According to Wikipedia, it is an incapacitating fatigue with the following characteristics:
- Of new or definite onset (not since birth)
- Unexplained by other medical cause
- Lasts for at least six months (from onset, not necessarily from when the patient becomes aware that the fatigue is an ongoing symptom)
- Is not improved by rest.
Wikipedia goes on to say that to qualify as CFS, for of the following eight symptoms must be present:
- Impairment of short-term memory and concentration
- Sore throat
- Tender lymph nodes
- Muscle pain
- Multi-joint pain
- Headaches of a new type, pattern, or severity
- Unrefreshing sleep or insomnia
- Post-exertional malaise (fatigue lasting more than 24 hours after exertion)
I would say that if you feel tired all the time, then your are chronically fatigued, by definition, although you may not fit this narrow definition for something that is more or less recognized by the medical profession, and is defined by something that has no know cause, but still has a relatively precise definition.
Following up the Chronic Fatigue Syndrome path may provide you with value but:
What about Allergies?
Allergies can cause symptoms that are similar to Chronic Fatigue Syndrome, or even fit the definition exactly. My symptoms come close. But in my case, I know the cause. Actually, causes. As long as I avoid wheat, milk, mould, yeast and dust, I’ll be pretty much all right.
So if you have something resembling Chronic Fatigue Syndrome, it is well worth finding out if you have allergies.
You can get tested (there are many types of tests), and you can try diagnosing your allergies through process of elimination.
