Fatigue is a symptom that can have many causes, and research into fatigue has shown that most of them are not related to a medical condition.
Facts about fatigue
Your doctor will use information from your medical history and from any examinations they conduct to decide what further steps may need to be taken to help treat or manage your fatigue.
There is no test specific for fatigue, only tests that may help identify a physical cause. The decision about whether to have a test and what type of test to have will depend on your individual situation.
Studies have shown that a medical explanation is found in only about 4% of people with fatigue who go on to have some form of testing. So, for every 100 people who are recommended for some form of test by their doctor to help find out why they are experiencing fatigue, a medical condition will be identified in only about four cases.
It is important to understand that medical tests are not always accurate in their diagnosis. Sometimes they pick up a problem when there isn’t one (this is called a false positive), and sometimes they can miss a diagnosis (this is called a false negative).
So you may want to discuss the pros and cons of medical tests with your doctor.
