How to Unclog a G-Tube Feeding Tube

Gastrostomy tubes (G-tubes) can get clogged, making feeding impossible. Regular preventive care of a G-tube reduces the likelihood of clogs, but it does not eliminate clogs 100 percent of the time. Some people are more prone to clogs than others. It is important to remove a clog as soon as it is noticed. G-tube clogs can often be removed at home. When home care fails to remove clogs, medical attention must be sought.

Wash your hands with soap and water to reduce the chances of introducing bacteria into the feeding tube.

Prevent future clogs in the feeding tube by using a syringe to flush warm water through the feeding tube before and after every feeding. Ask a doctor for a recommendation on the proper amount of water to use for regular G-tube flushing.


If clogs develop regularly in the feeding tube, ask a doctor to prescribe a tube unclogging medication.
