People with advanced cancer often notice changes in their appetite. This may be because of the cancer itself, treatment, or other side effects such as tiredness, nausea or vomiting, taste changes, pain, lack of activity, or depression.

Overview
| Importance of eating | A loss of appetite often leads to weight loss and malnutrition. Eating is important to help you maintain your strength, function and quality of life. However, it’s not necessary to force yourself to eat; this may only make you feel uncomfortable and cause vomiting and stomach pain. |
| Using nutritional supplements | Food-type nutritional supplements can increase nutrient intake. These are used as snacks between meals. Many pharmacies and supermarkets sell these specially formulated nutritional supplements. You do not need a prescription, though it may be cheaper if you have one from a doctor or dietitian. Your health care team may suggest a brand to try. |
| Understanding cachexia | People with advanced cancer may develop a muscle-wasting syndrome known as cachexia. This means the body isn’t using protein, carbohydrates and fats properly. Your doctor or dietitian will discuss ways to manage cachexia, which may include nutritional supplements or medicines such as appetite stimulants. |

Ways to manage loss of appetite
- Good nutrition can improve quality of life, but if you’re not feeling hungry then it’s okay to focus on eating foods that you enjoy to help stimulate your appetite.
- Eat what you feel like, when you feel like it. Don’t worry so much about timing or set meal times. You could have something lighter like cereal for dinner or a main meal at lunch.
- Use a smaller plate – a big plate full of food may put you off eating.
- Relax dietary restrictions. With advanced cancer, maintaining your weight is more important than avoiding full-fat foods like whole milk or yoghurt.
- Add flavour to foods with lemon or lime juice, fresh or dried herbs and spices.
- Add ice-cream or cream to some fruit or into a smoothie to increase kilojoules and nutrients.
- Try soft foods or clear liquids, which are easier to digest.
- Sip on juice, cordials, smoothies, soft drinks and sports drinks during the day to help keep you hydrated.
- Make meals as enjoyable as possible, e.g. play music, light candles or eat dinner with family or friends.
- Gentle physical activity can stimulate appetite. You could try taking a short walk around the block or some easy exercises.
- Speak to your doctor about trying some medicines that could help improve your appetite.
- See a dietitian for information about nutritional supplements, such as protein shakes, to ensure you don’t lose too much weight.

It was very important for our family and friends to be well informed about the ongoing problems with eating and digestion that occur during surgery. Having support helped us adjust to the changes.
