This is the reason causing malnutrition.
Cause of malnutrition in cancer patients 2. consume excessive amounts of cancer cells with the characteristics of propagation speed, therefore need to consume more nutrients. Moreover, in the case of nutritional deficiencies, cancer cells have an advantage in normal cells the ability to capture nutrients; tumor itself and the secondary infection caused by fever, body repair due to radiotherapy, chemotherapy and surgery due to injury, all needs extra nutrition. For all these reasons, cancer patients are vulnerable to malnutrition.Malnutrition can cause weight loss, anemia,, system dysfunction, decreased physical fitness, decreased disease resistance and a series of adverse changes in the body. These can be a more effective treatment, so that the reasons of deterioration. It is worth mentioning that the deterioration of the condition will increase the psychological burden of patients, undermine confidence and fighting spirit to overcome the disease, the results of a further decline in appetite, immune function and further reduction, the condition further deteriorated.
