Changes in Appetite
Appetite changes, whether an increase or decrease in customary appetite, are very common in people with cancer, especially those in cancer treatment and those with advanced cancer. Some common contributors to changes in appetite:
- Certain drugs, such as steroids used to treat some cancers and/or to manage symptoms, may increase appetite.
- Antidepressants can increase or decrease appetite.
- Chemotherapy for breast cancer may cause some women to experience intense food cravings.
- Some symptoms of cancer or side effects of cancer treatment can decrease appetite: nausea, mouth sores, dry mouth, fatigue, pain, tumor pressure on organs, bloating and constipation.
- Emotions such as depression and anxiety can affect appetite.
- The cancer itself can decrease appetite and cause anorexia by secreting chemicals that signal “fullness” to the satiety center of your brain.
- Taste changes that make foods taste unpleasant and unappetizing may also affect appetite.
- Increased sensitivity to food odors can also cause nausea and decrease appetite.
Managing Changes in Appetite
Many complementary approaches may be helpful with appetite changes. Because some supplements and other therapies can cause adverse effects or interfere with other therapies, be sure to have your doctor or pharmacist check for interactions. Tell your healthcare providers about all the therapies and approaches you are using or considering.
- Dietary strategies such as eating six small meals throughout the day and eating a variety of nutrient-dense high protein, high calorie foods can help with reduced appetite. For more information on dietary strategies, refer to these resources:
- Mild, brief exercise can stimulate appetite.
- If emotions and stress are affecting appetite, then mind-body approaches may help.
- Acupuncture/acupressure may help in addressing appetite directly and/or in relieving symptoms such as pain or nausea.
- Some natural products that relieve appetite-affecting symptoms may also be helpful, such as ginger for nausea. Search our Therapy Summaries for a full list of products.
- Some traditional herbal teas may stimulate appetite:3
- Gentian extract (from bitters) (WebMD) may stimulate appetite.4
- Supplementation with zinc (About Herbs) or omega 3 fatty acids may be helpful.5
- Medical cannabis may be recommended to improve appetite, but clinical evidence to date is insufficient to support its use.6
