Chemotherapy and hormone therapy cause different nutrition problems.

Side effects from chemotherapy may cause problems with eating and digestion. When more than one chemotherapy drug is given, each drug may cause different side effects or when drugs cause the same side effect, the side effect may be more severe.

The following side effects are common:

• Loss of appetite
• Nausea
• Vomiting
• Dry mouth
• Sores in the mouth or throat
• Changes in the way food tastes
• Trouble swallowing
• Feeling full after eating a small amount of food
• Constipation
• Diarrhea

Patients receiving hormone therapy may need changes in their diet to prevent weight gain.
