Symptoms for Chronic Fatigue Syndrome (CFS)

Chronic fatigue syndrome is a tricky disease to diagnose because many of its symptoms are similar to the symptoms of other types of disorders. As the name suggests, chronic fatigue syndrome involves excessive tiredness (or fatigue) that develops over a period of time and can become debilitating to a person’s quality of life.

However fatigue or prolonged fatigue which it really is in this instance, is a factor inliterally hundreds of different kinds of illnesses and therefore isolating the one trait that makes this disease that of chronic fatigue syndrome is not easy for doctors and healthcare practitioners. For example 10 to 25 percent of all patients suffering from one type of health problem or another find themselves experiencing fatigue.

It is important to differentiate that fatigue that accompanies CFS from regular fatigue that strikes everyone from time to time. It is normal to feel over tired after a few sleepless nights or after a stressful event or if one is really nervous about something that is coming around the corner.

The fatigue of chronic fatigue syndrome is incapacitating and intense, bordering on severe and it is not improved upon by a good night’s sleep or even a couple of good night sleeps. As well taking naps and catching up on rest in every way possible will not make the condition go away.

Chronic fatigue syndrome can be made worse by other kinds of mental or physical problems and it can drastically affect an individual’s quality of life as energy levels quickly can become depleted which can decrease the sufferer’s level of stamina. With little or no energy, a person will begin to change the way she lives her life and often many activities that a person once enjoyed disappear.

CFS affects all areas of a person’s functioning and this includes their personal life, their social life, their occupation and so forth.

A diagnosis of chronic fatigue syndrome can only be made conclusively after a series of tests has been done on the patient, however if a person has been suffering from unexplained and prolonged fatigue for a period of six months or longer then CFS is likely to blame. If the patient also exhibits a number of other characteristic symptoms then the doctor is inclined to lean towards a diagnosis of chronic fatigue syndrome.

The characteristic symptoms of chronic fatigue syndrome are often referred to as primary symptoms and there are eight in total.

First of all if a person suffers from cognitive dysfunction, which includes problems concentrating, or impaired memory or even memory lapses then CFS could be to blame.

If a person suffers from “post exertional malaise” that lasts for more than a 24-hour period and it occurs after a strenuous mental or physical exercise then it is likely caused by CFS. If a person wakes up feeling unrested and unrefreshed morning after morning that is another symptom of CFS.

Other characteristic symptoms of CFS include persistent pain in the muscles, pain in the joints that does not include any degree of inflammation or swelling, headaches that are different than any a person has experienced before or headaches or a more intense variety, a sore throat unrelated to a cold or other respiratory condition and cervical or axillary lymph nodes that are tender.


Medical tests for Chronic Fatigue Syndrome (CFS)

A diagnosis of CFS is generally not made until a doctor does a complete physical examination on a patient and then sends the person for a series of medical tests. The excessive fatigue must be around for approximately six months before the doctor will even begin to suspect that CFS is to blame.

Laboratory tests are generally undertaken first as they are not expensive to do and they are relatively simple for the patient and the results will come back from the laboratory very quickly. These tests generally include a blood count test, thyroid function test, liver function test, urine test and a sedimentation rate. All of these tests are conducted to rule out any number of other health problems. Be aware however that no laboratory tests whether it be blood, urine, liver or any other kind is able to diagnose CFS simply by the results of that one test.

If any one of these tests comes back abnormal then this still could mean that the person is suffering from CFS but it could be any number of other disorders as well. A doctor then must look closer to other types of health problems.

Exercise tests are usually the second step. In general people who are suffering from chronic fatigue syndrome are not able to exercise to the same level as those in the general population who do not struggle with the disorder. Exercise tests can help to determine whether a person is suffering from a mild version of CFS or whether it is moderate or severe.

Research studies looking into exercise tests and their benefits to CFS patients have found that those who suffer from CFS have “higher than normal ratings of perceived exertion (RPE)”. What an RPE is is basically the effort it takes energy wise for an individual to exercise. The scores for RPE can range from 0, which stands for falling asleep to 20, which ranges for maximum all out exertion. Some studies however refute the validity of past studies and have found no significant difference between the two at all.

It was once believed that simply measuring blood pressure was enough to determine whether a person suspected of having CFS suffers from the problem due to a “neurally mediated level of hypotension” which is an abnormal drop in a person’s blood pressure. A tilt test can help to determine more. A tilt test is when a person lies down on a table that is tilted approximately at a 70-degree angle for a specified length of time (this may vary from patient to patient).

If the patient feels nauseous, lightheaded, faint or dizzy after a very short period of time then this is a sign of neurally mediated hypotension and thus lends itself closer to a diagnosis of chronic fatigue syndrome.

It will be up to a doctor whether he feels it is necessary to send a patient for one of the other tests or a variety. The deciding factors will often be the number of symptoms a person is experiencing and how much their present health condition is affecting their day-to-day life. First however other health conditions must be ruled out, such as depression, pregnancy, fibromyalgia or a variety of bacterial and/or viral infections.
