Nutrition help from your medical team

Nutrition help from your medical team

People with cancer can experience nutrition-related problems during cancer treatment

These problems may include decreased appetite, mouth sores or digestive issues, such as nausea or diarrhea. It can be challenging to eat enough to stay strong during cancer treatment. Your medical team can provide you with options so that you can eat enough calories, protein and other nutrients.

Talk to your medical team about nutrition

It is important to talk with your medical team about nutrition regularly. They can tell you what nutrition problems you may experience during your cancer treatment. This will help you know when to tell your oncologist about issues, such as difficulty eating or weight loss. If your symptoms are not improving, he or she may adjust your medication to help you feel better.

It is also important to discuss with your medical team any changes to your diet and any over-the-counter vitamin, mineral or herbal supplements you may be taking. They will make sure that your diet and any supplements you take are safe and healthy for you.

How an oncology dietitian can help you

When it comes to helping you with nutrition, an oncology registered dietitian can be an important member of your healthcare team. A registered dietitian (RD) is a food and nutrition expert who works in a wide variety of healthcare settings.

An oncology registered dietitian can:

  • Review your current diet to see if you are eating enough calories and protein to meet your nutritional needs
  • Help you plan meals that are healthy and nutritious
  • Provide useful suggestions to help manage symptoms of cancer treatment
  • Review a food and symptom journal. A food and symptom journal is a record of your current symptoms and the foods you are able to eat. It is helpful to share it with your dietitian to show him or her how you are eating
  • Advise you on foods or supplements to avoid. Some foods or supplements can interfere with your medicines. For example, some people do not know that grapefruit can interfere with many medicines, including medicines for cancer

Where to find an oncology dietitian

You can sometimes find an oncology registered dietitian on staff at your cancer center. If there is no oncology registered dietitian, ask your doctor or nurse if he or she has one to recommend in the community. You can also search online through the Academy of Nutrition and Dietetics’ “Find an Expert” feature at eatright.org.
