Fever and Fatigue

Fatigue is a common symptom if you have a fever.
This combination of fever and fatigue can happen for several reasons.

Firstly - one of the major effects of fever is to cause a gradual loss of body fluid. This results in dehydration and (if it becomes severe) an imbalance in the bodies salt levels. Low sodium and low potassium are both likely to cause profound feelings of fatigue.

If you have a fever then it's crucial to drink as much water as you possibly can. Try to drink enough water to ensure that you are passing urine regularly - and aim to make that urine pale yellow in color. If it looks dark - drink more!

Secondly - fever is usually an indication that your body is trying to fight off an infection - either a virus or a bacterial infection. The fact that your immune system is working full tilt to fight the infection can lead directly to feelings of fatigue and tiredness.

If you are unwell with a persistent fever or prolonged fatigue then you need to see a doctor. Don't rely on websites for medical advice - seek a medical opinion.
