What is a Gastrostomy Tube (G-tube) used for in a medical context?

A Gastrostomy Tube, commonly referred to as a G-tube, is specifically utilized to deliver nutrition directly into the stomach. This medical device is inserted through the abdominal wall and into the stomach to provide a means of feeding individuals who are unable to eat by mouth due to various health conditions. These may include neurological disorders, oral cancers, or severe swallowing difficulties.

The primary function of a G-tube is to ensure that patients receive the necessary nutrients and hydration when oral intake is not possible or is contraindicated. This is integral for maintaining overall health, preventing malnutrition, and supporting recovery in patients with specific medical needs.

While other devices serve different medical purposes—such as assisting with breathing, draining fluid, or monitoring blood pressure—they address distinct clinical situations and do not overlap with the primary role of a G-tube, which is focused on nutritional support.
