The starving patient: supportive care for people with cancer.

Unintentional weight loss in people with cancer is associated with decreased quality of life and increased mortality. Addressing risk factors that lead to weight loss may improve quality of life and prevent cachexia. Specific, individualized counseling is the most beneficial and economic intervention for nutritional health. Appetite stimulants promote oral intake, and oral supplements help to meet the increased need for calories and protein during the course of the disease and its treatment. Utilizing the gut for digestion and absorption of food maintains the critical functions of the bowel lumen. Tube feeding and parenteral nutrition may be indicated for prevention of malnutrition in some disease conditions and during certain types of cancer treatment.
