A lot of times, situations arise wherein people are not able to take the essential nutrients in the body through their mouth. It is, however, essential to ensure that the nutrients reach the body. The same is the case with babies. To assure that the adequate level of nutrients reaches the body, other ways have been developed.
In cases where a person’s oral intake stops or is reduced, food has to be transferred through the gastrointestinal tract. Such kind of feeding is mostly tolerable for most patients. Hence, it is a commonly used manner of transferring food to the body.
The two commonly used tubes to feed such patients are the G-tube and the J-tube. Both these tubes help to supply the nutrients to the bodies of people whose gastrointestinal tract is functional, but they are unable to take in food using their both.
G Tube vs J Tube
The difference between the G-tube and the J tube is that the G-tube stands for a gastrostomy feeding tube and is inserted to the stomach by a small cut in the abdomen. On the other hand, the J-tube stands for a jejunostomy feeding tube and is inserted into the middle part of a small intestine.

J tubes are mostly long tubes or in the form of buttons. J Tubes can be placed either laparoscopically( direct incision to the small intestine) or thorough a gastric bypass procedure. They are suitable for people who are suffering from chronic vomiting or for those who are at high risk for aspiration. The only drawback is that they sometimes might cause irritation.
