About Fatigue

One of the problems of dealing with fatigue is that it is a non-specific symptom that is associated with a host of different medical conditions from the fairly minor to chronic illnesses. Just some of the conditions that are associated with fatigue include: Irritable Bowel Syndrome (IBS), food intolerances, anaemia, diabetes and HIV. As well as being a symptom of other conditions, severe fatigue can also be a condition in itself in the form of Chronic Fatigue Syndrome.

One of the most efficient and effective ways of diagnosing the cause of your fatigue can be to take tests to rule out some of the most common, and treatable, causes of fatigue, such as an underactive thyroid (hypothyroidism) and anaemia (iron deficiency). Our health screens include general tests that assess and measure some of the body's major organ functions as well as evaluating your blood, and can therefore also be a valuable tool in diagnosing the cause of your fatigue. As fatigue can also be caused by a number of different lifestyle factors (i.e. poor diet, sleep problems) a health screen will help you to assess the overall effect that your lifestyle is having on your health and physical wellbeing and to therefore make better informed decisions.

Why have a Fatigue Test?
