The body requires nutrients for cell growth, cellular functions, muscle contraction, wound healing, and other vital activities. Nutrients enter the body as food and are absorbed as chemical reactions break down food into molecules that enter the bloodstream where they are distributed throughout the body.

Surgery, trauma, malignancy, and other catabolic illnesses cause a nutritional imbalance that, if prolonged, can have a dramatic impact on the patient that could ultimately lead to death.

Healthcare professionals can restore or maintain the patient's nutritional balance by administering nutritional support therapy to replace nutrients that the patient lost. There are two types of nutritional support therapies: enteral and parenteral.

Enteral nutritional support therapy introduces nutrition into the patient by mouth or a feeding tube that is directly inserted in the stomach or small intestine. Parenteral nutritional support therapy administers high caloric nutrients through large veins such as the subclavian vein.
