Living well with cancer: Why Malnutrition Matters?

By October 11, 2023No Comments

What is Malnutrition?

Malnutrition is characterised by loss of weight, loss of muscle, and loss of subcutaneous body fat. Cancer-related malnutrition can occur due to the type of cancer, treatment effects, and restrictive ‘cancer diets’. Cancer-related malnutrition is thought to affect 30-40% of people with cancer, yet it is under-recognized and undertreated. Research suggests 50% of people with cancer-related malnutrition are not receiving care from a dietitian. Part of the challenge is awareness, both among healthcare professionals and the general public.


Why Malnutrition Matters?

Malnutrition can have a big effect on your health, treatment, and recovery and should be prevented as malnutrition can:

  • worsen treatment side effects
  • reduce muscle mass and strength, making everyday tasks more difficult
  • reduce immunity and increase risk of infection
  • cause treatment delays and reduce its effectiveness
  • increase time in hospital

What can be done to prevent or manage malnutrition?

  • It is recommended people with cancer have regular malnutrition screening. This can be done by nurses or other staff within healthcare settings using a validated tool. You can also complete your own here: Malnutrition screening tool – Peter MacCallum Cancer Centre
  • Prompt referrals to a dietitian for people ‘at risk’ of or experiencing malnutrition
  • Regular monitoring of weight (weekly). If you are losing weight without trying, please ask your nurse or health care provider for a referral to a dietitian or reach out to a dietitian directly
  • Meet with a dietitian who will carry out a nutrition assessment and provide individualised medical nutrition therapy to help prevent or treat malnutrition
