The strongest have their moments of fatigue.
The impact of fatigue
In Canada, fatigue is one of the top 10 reasons patients visit their family doctor. About 7.5% of people are affected by chronic fatigue. And for some, fatigue is so severe that it interferes with other aspects of their life.
What is fatigue?
Fatigue is a feeling of tiredness, weariness, exhaustion, or lack of energy. There are many possible causes to fatigue and usually more than one is at play. Often, fatigue is caused by overwork, inadequate sleep, poor diet, stress, lack of exercise, prescription or over-the-counter medications, seasonal viral illnesses (e.g., common cold), and/or substance use (alcohol, caffeine, recreational drugs). Sometimes fatigue heralds an underlying medication condition (e.g., cancer, anemia, depression, etc.) which warrants a visit to a doctor.

When should I seek help?

What are the treatment options for fatigue?
Different treatment options are available depending on your symptoms and other conditions.
- If an underlying medical condition was found to cause or contribute to fatigue (e.g., iron deficiency anemia), the first step would be to correct it (e.g., taking iron supplements).
- In some cases, medications can be prescribed to help with fatigue. For example, an antidepressant might be helpful for someone with fatigue and symptoms of depression.
- Of all the different treatments for fatigue, exercise has been proven to be the most beneficial. Regular exercise decreases fatigue more effectively than rest! Different people have different limits when it comes to exercise; check with your doctor or rehab team before engaging in a new exercise regimen.
- Sleep optimization and stress management are essential stepping stones to properly manage fatigue.
- Many people find cognitive and behavioural modifications helpful. This is not a cure for fatigue but rather strategies to help them cope better with fatigue.
