Fatigue (weariness or tiredness) is a common side effect when undergoing cancer treatments. These treatments may include chemotherapy, radiotherapy, surgery, and hormone therapy. Treatments may also cause changes in sleeping habits, changes in taste and appetite, all of which can contribute to fatigue. Fatigue occurs because your body is using a lot of energy to rebuild normal cells.

Fatigue can also be due to dealing with a wide range of emotional issues related to your diagnosis. Emotional issues may include stress and difficulty coping, depression, anxiety, grief and loss, family and relationship problems, treatment side effects and sexual problems.

Fatigue commonly builds up over the time of your treatment, especially if you have had a combination of treatments and your treatment continues over several months or longer.  This will vary for each person. Signs of fatigue may include feeling worn out, a heavy feeling in your arms and legs, finding it hard to do your daily activities or to think clearly (lack of concentration).

Tips you may find helpful:

• Identify when you feel you have the most energy - morning or afternoon and plan important activities for this time.
• Ensure you are eating and drinking well.
• Learning to say "NO" to requests (look after yourself).
• Counselling can provide ways to manage stress.
• Rest for short periods during the day.
• Limit guests, visitors and telephone calls when you are feeling fatigued (they will understand).
• Stick to a routine of light regular exercise such as short walks.
• Keep the activity or exercise for earlier in the day.
• Spread out activities and possibly ask others to help with tasks.
• Try newer activities such as handicrafts, reading or relaxation techniques.
• Your doctor, physiotherapist, occupational therapist, social worker or nurse may be able to suggest ways to help you cope better with your fatigue or link you into services to assist you whilst you are fatigued.

If you are not sleeping well at night, discuss this with your doctor or nurse. If you have a job, it may be possible to take a few weeks off work or to reduce your hours at work while you are having treatment. Many people benefit from a break from their work and other responsibilities after completing their treatment as this is when any side effects and tiredness tend to be at their worst. If you have any questions or concern speak to your doctor or nurse.
