Fatigue during cancer treatment

Managing fatigue during cancer treatment

If you’re experiencing cancer-related fatigue, don’t be alarmed – fatigue is common in people with cancer, and there are strategies to help you cope.

The following information has been put together to help you understand some of the causes of fatigue, advice to help you manage symptoms of fatigue and answered some common questions we get from our patients.

What causes cancer-related fatigue?

Cancer-related fatigue can be caused by the cancer itself as well as cancer treatments such as chemotherapy, surgery, radiotherapy, bone marrow transplants or hormone therapy.

Changes in hormone levels and proteins that regulate inflammatory processes can lead to increased levels of fatigue. Some cancer treatments and cancers that have spread to the bone marrow can reduce the amount of red blood cells in your body which can cause anaemia (or low iron), making you feel more tired.

Other cancer treatments may have side-effects, such as nausea or vomiting, which can reduce your appetite and impact on your sleep, contributing to your fatigue.

Certain tumours secret toxins which can prevent healthy cells from producing necessary nutrients such as calcium and potassium for optimal muscle function, resulting in weakness and tiredness.

While fatigue may feel debilitating and overwhelming, there are many ways to manage your symptoms: 

• Get at least 8 hours of sleep each night – and, take short 30-minute naps during the day if possible

• Drink plenty of fluids – dehydration can make you feel more tired 

• Eat healthy, balanced meals or snacks – eat at regular intervals throughout the day to help maintain your energy levels, and speaking with a specialist dietitian to assist you in healthy meal ideas may be helpful

• Don’t do too much each day – prioritise the most important tasks

• Increase your opportunities to sit down – take a chair into the shower, play with your children on the floor, and encourage cuddles in your lap (rather than lifting or carrying children or pets)

• Let your family and friends help – accept help in the form of making freezer meals, cleaning, gardening, shopping and housework

• Exercise throughout the week – regular exercise will help to boost your energy levels, and you can speak to your specialist team about a personalised exercise program

• Practice relaxation techniques – yoga and breathing exercises can help restore balance and energy levels.

Cancer fatigue and emotional wellbeing

It is common to feel sadness and even despair with your cancer-related fatigue. Having a good network of friends, family and support groups that you can reach out to when your symptoms feel unmanageable is important.

If you are concerned, or wish to find a support group near you, speak with your specialist for information specific to your local area.
