What is the Difference Between Enteral and Parenteral Nutrition

March 1, 2023 | by Yashaswi Pathakamuri | Posted in FAQ's

Enteral nutrition and parenteral nutrition are two different methods of providing nutrition to a person who is unable to eat or digest food normally. Enteral nutrition is given through the digestive system, while parenteral nutrition is given directly into the bloodstream. The choice of method depends on the person’s condition and ability to absorb nutrients, as well as the risks and benefits of each method.

The main differences between these two types of nutrition are as follows:

  • Enteral nutrition: This method involves delivering nutrients directly into the person’s digestive system. Enteral nutrition is administered through a feeding tube that is placed into the stomach or small intestine. This method is generally used when a person is able to absorb nutrients but is unable to eat or swallow food normally. Enteral nutrition can be given in liquid form, such as a special formula, or as blended foods.
  • Parenteral nutrition: This method involves delivering nutrients directly into the person’s bloodstream. Parenteral nutrition is administered through a catheter that is placed into a vein, usually in the arm or chest. This method is used when a person’s digestive system is unable to absorb nutrients, such as in cases of severe illness, surgery, or injury. Parenteral nutrition is a more complex and expensive method of providing nutrition and requires close monitoring by healthcare professionals.
