Learned food aversions also occur in cancer patients receiving chemotherapy. This response is usually established when food ingestion has been temporally paired with chemotherapy application and its associated nausea and vomiting. This problem can occur even after a single course of chemotherapy. Any type of food may be targeted and highly preferred items eaten every day are often most problematic. Comparing lung and breast cancer patients, Mattes et al found pretreatment reductions in appetite in 57 percent of lung cancer patients and in 19 percent of breast cancer patients studied. ventolin 100 mcg
Aversions were formed to food ingested anywhere from 24 hours before to more than 24 hours after treatment and had a median duration of less than one month. An emetic episode was not a necessary condition. Although nausea, vomiting, and appetite disorders are rarely considered when evaluating the results of clinical trials, these side effects may have an important impact on the patients well-being. Prevention and management strategies for these problems should be studied, especially in small cell lung cancer, where toxic regimens are universally used. In addition to the effective use of antiemetics, behavioral interventions should be used to reduce or prevent anticipatory nausea and vomiting, food aversions, or increased anxiety and physiologic arousal.
