what if fatigue
Always see your doctor for diagnosis if you are suffering from chronic tiredness. 1  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.
