Weight, nutrition, quality of life-Perspective of oncological patients

Nutrition is associated with pleasure and quality of life. The majority of oncological patients experience tumor-associated and treatment-associated nutrition-related symptoms and malnutrition. Consequently, the perception of nutrition during the course of the disease is increasingly more characterized by negative associations, which may persist for years after the end of treatment. This leads to a decreased quality of life, social isolation and a burden for relatives. In contrast, weight loss is initially positively perceived, especially by patients who previously perceived themselves as being overweight, until malnutrition becomes evident and leads to a decreased quality of life. Nutritional counseling can prevent weight loss, relieve adverse side effects, improve the quality of life and reduce mortality. Patients are not aware of this and the German healthcare system lacks structured and firmly established access pathways to nutritional counseling. Therefore, oncological patients need to be informed about the consequences of weight loss at an early stage and low-threshold access to nutritional counseling needs to be comprehensively implemented. Thus, malnutrition can be recognized and treated at an early stage and nutrition can contribute to a higher quality of life as a positively perceived daily activity.
