A G-tube is a flexible tube that enters the stomach through a surgical incision called a stoma. Medical food can be given through the G-tube directly into the stomach.

Anytime a device such as a G-tube enters the body there is a risk of infection; therefore, to keep the patient healthy, it is important to wash hands frequently, keep the stoma clean and dry, and wash feeding supplies every day.


Things to Know if You Have a G-tube

Helpful Tips

There are many things to keep in mind for G-tube feeding.

  1. Make sure the G-tube is clean and free of obstruction by flushing the G-tube with water immediately before and after feeding.
  2. Be aware of any changes in the length of the G-tube. These changes could indicate that the G-tube is out of place..
  3. Talk to a Doctor if you do not see fluid when testing the position of your G-tube. Not seeing fluid when you pull back with a syringe could indicate that the G-tube is out of place.
  4. You should not have difficulty breathing nor should you choke during G-tube feeding. Discomfort during feeding could mean that the flow is too fast.
  5. Sit-up during feeding, which will help the feeding flow naturally.
