Why you may feel tired

You may feel tired during your radiotherapy treatment, because the body has to repair damage caused by the radiotherapy to healthy cells. If you have to travel to your treatment each day, you may get even more tired.

Tiredness tends to creep up on you as you go through your treatment. So you may not feel tired at the beginning of your course, but you are very likely to by the end. You may feel like having a sleep 1 to 2 hours after each radiotherapy treatment. This tiredness is called fatigue and you may also feel weak and as though you have no energy.

Tiredness can still be a problem for some months after your treatment has finished. Our tiredness and cancer section has tips on treating it. Some research into treating fatigue shows that exercise may be more helpful than rest. Try to schedule in a short walk each day. You may find that you can gradually increase the distance. Pick the time of day when you are feeling least tired. Do remember though, that however far you walk, you'll have to walk the same distance back, so try not to overdo it.

 

Tiredness after brain radiotherapy

People having radiotherapy for brain tumours can be particularly affected by tiredness and it can be worse if you are also taking steroids. The tiredness often reaches its maximum 1 to 2 weeks after the end of treatment. A small number of people are asleep virtually all day for a short time after a long course of radiotherapy to the brain. You may hear this called somnolence syndrome.

 

Tips for saving energy

There are many things that you can do in your everyday life that help you use up less energy. Taking short cuts on some things or getting help from other people can help you feel less tired. Do remember though, that it is good for you to have some exercise. A short walk every day may help you to feel better.

Try some of the following to help save your energy

  • Try not to rush
  • Plan ahead where possible
  • Give yourself plenty of time to get places
  • Don't travel in peak hour traffic if you can avoid it
  • Put chairs around the house so you can stop and rest if necessary
  • Sit down to dry off after a bath or put on a towelling dressing gown and let that do the work
  • Get an occupational therapist or social worker to get hand rails put up in your bathroom to hold on to when getting in or out of the bath or shower
  • Prepare your clothes and lay them out in one place before you dress
  • Sit down to put most of your clothes on
  • When dressing, try not to bend down too much – bring your foot up on to your knee to put socks and shoes on
  • When dressing, fasten your bra at the front first and then turn it to the back
  • Wear loose fitting clothes and things with few buttons to do up
  • Where possible do household tasks sitting down, such as peeling vegetables or ironing
  • Choose clothes that don't need ironing
  • Use a duster on a long stick and sit to do your dusting
  • Write a list of shopping and go when the supermarket is not busy or have food delivered
  • If you have children, play games with them that can be done sitting or lying down – for example, board games, reading books and drawing pictures
  • Ask family and friends for help with things like shopping, housework and collecting the children from school
  • You may find it easier to have lots of small meals, rather than the traditional 3 meals a day
  • Have plenty of nutritious snacks and drinks in stock that you can have whenever you feel like eating
  • Don't forget to do things that you enjoy – this may take your mind off things a bit and make you feel more relaxed
  • Buy ready made meals that you can quickly heat up rather than making food from scratch
  • You can buy ready peeled vegetables to save even more energy
