If you’re living with multiple myeloma, you may feel very tired or not have the energy to do day-to-day activities. Fatigue is the name for tiredness that doesn’t go away after rest or sleep. Almost everyone with myeloma experiences fatigue at some point.1

Below we’ve shared some of the reasons you may be experiencing fatigue and suggested some tips to help you cope with it.

What causes multiple myeloma-related fatigue?

One of the main causes of myeloma-related fatigue is anaemia. This means having a lower-than-normal number of red blood cells in the blood. In turn, this means less oxygen is carried around your body, which can make you feel tired or weak.1,2

Many treatments for myeloma cause side effects. Some of these cause fatigue.3  It’s important to balance the benefits of taking a treatment with the potential side effects, to decide the best treatment for you.

Ways to help you cope with fatigue

Fatigue is a type of tiredness that doesn’t go away with rest. But some people are able to manage their fatigue with lifestyle choices.1 We’ve shared some of these below:

Food and diet

  • Getting good nutrition from food is an important part of keeping the body healthy. This means including a good balance of protein, carbohydrates, fats, fibre, vitamins, and minerals. For some people, vitamins or other supplements may be prescribed to help reduce fatigue.1,4
  • Drinking plenty of water is important, as being dehydrated can sometimes make fatigue worse. Most people in the UK are recommended to drink 2 to 2 and a half litres of fluid each day.1
  • Remember, it’s important to speak to your doctor or healthcare team before making any dietary changes. They will be able to let you know what is appropriate.

Exercise and activities

  • It may sound strange, but physical activity and exercise may help with feelings of fatigue. This is because a lack of physical activity may make some people feel more tired and less able to sleep. A lack may also lead to low or frustrated feelings, especially if they used to be very active.1,4
  • Yoga may be a nice, gentle exercise to help to improve energy levels.
  • Since having multiple myeloma can cause pain and bone damage, it is important to talk to a doctor before beginning any new exercises or activities so that they can discuss any possible risks. They may also provide a referral to a physiotherapist who can put together a personalised exercise plan for you.1

How to talk to doctors about fatigue

Fatigue can be difficult for doctors to recognise, as there isn’t a test to measure it. Instead, doctors rely on how someone describes their fatigue to them. The questions below might help you to describe your fatigue to a doctor:5

  • When did the fatigue start?
  • When did you first notice that this fatigue was worse than fatigue or tiredness you’ve had before?
  • How long has it lasted?
  • Does anything make it better? Worse?
  • Are there times of the day when you notice it more?
  • How has the fatigue affected the things you do every day or the activities that give meaning and enjoyment to your life?
