Cachexia

Cachexia is usually a symptom of advanced cancer. It’s more common with cancers of the digestive system, such as pancreatic and stomach cancer, and lung cancer. 

When you have cancer, your body may start to work in a different way. You may have increased levels of inflammation and changes to your metabolism. These changes can lead to your body breaking down muscle and fat for energy instead of the food you eat.

• Having little or no appetite
• Losing weight, muscle and fat, even if you are eating
• Feeling very weak
• Feeling full after eating small amounts
• Anaemia (low levels of red blood cells)

You should talk to your medical team if you’re worried about the symptoms of cachexia. Although there is no treatment that can get rid of advanced cachexia, your medical team will support you to feel as well as possible. 

There is no treatment that can reverse or stop cachexia yet, although drugs are being researched. It is a good idea to meet with a dietitian who can give you advice – for example, about meal choices. Try to seek support from a dietitian early on, if you notice unintentional weight loss or changes in your appetite.

Your doctors can prescribe appetite stimulants and anti-sickness medications, which may help you eat a little more. The aim of these treatments is to help improve your quality of life.

Advanced cachexia is very different to general weight loss or muscle loss. Doctors can’t reverse it fully even if you are able to eat. Feeding through a tube is not effective either.

Try to join in with the social aspect of family meals – even if you can’t eat much. Try to explain cachexia to your family and friends, so that they don’t put pressure on you to eat if you don’t feel able to.

Taking a little exercise, if you’re able, can also help you to feel a little better and may help to build muscle mass. Ask your doctor about what type of exercise might be suitable for you.

Cachexia and its effects can be very upsetting. If you feel your mood is consistently low, it is important to seek help. You may be experiencing depression because of your diagnosis and side-effects. Your GP, cancer nurses and medical social workers can all support you and your family and can suggest other professionals who can help. For example, psychologists, psychotherapists and psychiatrists.

You can also ask if there is a psycho-oncology service at the hospital. This service helps patients and their families deal with the psychological aspects of cancer, such as depression.
