Radiation to the head and neck or parts of the digestive system may cause eating and digestion problems. You may lose interest in food during your treatment. Even if you are not hungry, you should try to eat protein and high-calorie foods. Doctors have found that patients who eat well can better handle their cancer treatments and side effects.

Coping with short-term diet problems may be easier than you expect. There are a number of guides and recipe booklets for patients who need help with eating problems. You can get a copy of our free booklet, Nutrition for the Person with Cancer: A Guide for Patients and Families, by calling our toll-free number, or you can read it on cancer.org.

The list below suggests things you can do when you don't feel like eating, and how to make the most of it when you do feel like eating.

• Eat when you are hungry, even if it is not mealtime.

• Eat 5 or 6 small meals during the day rather than 2 or 3 large ones.

• Vary your diet and try new recipes.

• If you enjoy company while eating, try to eat with family or friends, or turn on the radio or television.

• Keep healthful snacks close by for nibbling when you get the urge.

• If other people offer to cook for you, let them. Do not be shy about telling them what you would like to eat.

• If you live alone, you might want to arrange for programs like Meals on Wheels to bring food to you. Ask your doctor, nurse, or local American Cancer Society office about Meals on Wheels in your area.

• If you drink alcohol, ask your doctor if you should avoid alcohol during your treatment. Find out if it will interact with any medicines you are taking.

If you are able to eat only small amounts of food, you can increase the calories per serving by trying the following:

• Add butter or olive oil.

• Mix canned cream soups with milk or half-and-half rather than water.

• Drink milkshakes, instant breakfast mixes, or liquid supplements (in cans or bottles) between meals.

• Add cream sauce or melted cheese to your favorite vegetables.

Some people find they can handle large amounts of liquids even when they do not feel like eating solid foods. If this is the case for you, try to get the most from each glassful by making drinks enriched with powdered milk, yogurt, honey, or liquid nutrition drinks.

Talk to your health care team about any eating problems you may be having. They can help you find ways to feel better and get the nutrients your body needs.
