Enteral is an adjective pertaining to the digestive tract or the process of digestion, specifically referring to the administration or absorption of substances through the gastrointestinal system. The term "enteral" is derived from the Latin word "enteros," meaning intestine or bowel.
In medical contexts, enteral is commonly used to describe the delivery of nutrients, medications, or other substances directly into the stomach or intestines, bypassing the oral route. This method is typically employed when patients are unable to take substances orally or when the oral route is not feasible or effective. Enteral administration can be achieved through various means, including the use of nasogastric or gastrostomy tubes, through which substances are introduced into the stomach, or through jejunostomy tubes that deliver substances directly into the jejunum.
The enteral route offers several advantages, such as maintaining gut integrity, promoting the normal function of the digestive system, and ensuring efficient absorption of nutrients. It is often preferred over parenteral routes (such as intravenous) when enteral intake is possible due to these benefits. Furthermore, enteral feeding or medication administration can be tailored to meet the individual needs of patients in terms of volume, nutrient requirements, and absorbability.
Overall, enteral refers to the process of delivering substances directly into the gastrointestinal system, primarily the stomach or intestines, to facilitate digestion, nutrient absorption, and medical treatments.
