Tiredness: Information for patients and carers

Fatigue is a feeling of extreme tiredness or lack of energy that doesn’t always go away with rest. It can be physical, mental, or emotional. People often describe it as feeling drained, heavy, or like their body won’t do what they want it to.

Fatigue can affect:

• The ability to move around or do daily tasks
• Concentration and memory
• Mood and motivation
• Social interaction

• The illness itself (e.g. cancer, heart failure, lung disease)
• Side effects of treatments like chemotherapy or medication
• Pain or other symptoms interfering with sleep
• Anxiety or depression
• Poor nutrition or dehydration
• Moving about less

Fatigue often has more than one cause.

• If you feel low, anxious, or unable to cope with the change in energy levels
• If fatigue is new or has changed significantly as there may be a treatable medical cause such as low blood count (anaemia), infection, or medication side effects
• There are some medications (such as steroids) that may help with a boost of energy for a short period of time

• Prioritise: Focus on what matters most each day
• Plan ahead: Spread tasks throughout the day or week
• Pace yourself: Take regular breaks and rest when needed

Gentle movement or light exercise (such as walking or stretching) can surprisingly help maintain energy and reduce fatigue.

• Try to keep a regular calm sleep routine
• Limit naps to short periods during the day

• Eat small, regular meals
• Drink plenty of fluids

Talk to someone you trust about how you're feeling. Counselling or support groups can help if you’re struggling emotionally.
