You may lose or gain weight for various reasons, including the effects of the cancer and cancer treatment.
If you're underweight or losing weight you may need to include more protein and more energy in your diet. Good sources of protein and energy (calories or kilojoules) include: meat, fish, poultry, milk, and dairy products, eggs, legumes (e.g. baked beans, chick peas, lentils) and nuts. For extra protein, aim to include at least one higher protein food at each meal.
High protein foods and drinks should also be included as between–meal snacks. Nutritional supplements such as nourishing drinks may also be useful to help you gain weight.
You may also be encouraged to eat foods that are typically not considered as healthy foods as they can be high in fat and sugar. Including foods with extra protein, fat and sugar in your diet, for most people, will be for a relatively short period of time. If you have any concerns, discuss them with your doctor or dietitian.
Certain types of chemotherapy, hormone therapy and some medicines such as steroids can cause weight gain. These treatments can also cause your body to retain water, which can make you feel puffy and gain weight, or some treatments can increase your appetite so you feel hungry and eat more. Being tired because of the treatment may lead to decrease in activity. Being less active can also cause weight gain.
Generally, during cancer treatment is not a good time to deliberately lose weight. Try to maintain your weight throughout treatment. If you gain weight during treatment and are concerned, speak first to your doctor about it to work out how to best manage it. In situations where you've lost weight without trying, regaining at least some of this weight can help you better tolerate treatment.
Malnutrition occurs when there's an imbalance of energy, protein or other nutrients. Malnutrition is common in people with cancer and can impact your health and how your body responds to cancer treatment and recovery. It's possible to be malnourished even if you're overweight.
Many factors can increase your risk of malnutrition, including:
Many of the eating problems discussed can contribute to, or be signs or symptoms of, malnutrition and can lead to a reduced response to cancer treatments, increased side effects and possibly reduced survival.
Malnutrition can also lessen your strength, function and quality of life. Eating well can assist your health and progress before, during and after cancer treatments.
Regardless of where you have your treatment, at diagnosis and at frequent points throughout your treatment journey, you should be asked by hospital staff about your risk of malnutrition. You should be asked:
If you answer yes to one or both of these questions, you may be at risk of malnutrition. If this is the case, it's important to be referred to a dietitian for individualised advice.
Identifying your risk of malnutrition early is key to tackling it in the best way to improve your overall health. Malnutrition and weight loss can be prevented. It should not be considered an expected side effect from cancer or treatments. Speak to your doctor or dietitian about ways to lower your risk.
