Fatigue is a feeling of constant tiredness or weakness and can be physical, mental or a combination of both. It can affect anyone, and most adults will experience fatigue at some point in their life.
Each year, around 1.5 million Australians see their doctor about fatigue. Fatigue is a symptom, not a condition. For many people, fatigue is caused by a combination of lifestyle, social, psychological and general wellbeing issues rather than an underlying medical condition.
Although fatigue is sometimes described as tiredness, it is different to just feeling tired or sleepy. Everyone feels tired at some point, but this is usually resolved with a nap or a few nights of good sleep. Someone who is sleepy may also feel temporarily refreshed after exercising.
If you are getting enough sleep, good nutrition and exercising regularly but still find it hard to perform everyday activities, concentrate or be motivated at your normal levels, you may be experiencing fatigue that needs further investigation.
