A gastrostomy tube, also commonly referred to as a G-tube, is a feeding tube inserted into the belly to bring nutrition directly into the stomach. Gastrostomy tube feeding can help patients who are too ill to eat normally maintain a healthy level of nutrition. Generally, a G-tube is inserted by a surgeon during a procedure known as gastrostomy. The tube is inserted through the wall of the abdomen, directly into the stomach. It can be used to administer food, liquid, and even medication. A G-tube holder will keep the device in place to ensure the patient is fed normally and the tube avoids blockage.
