The G-Shirt

The G-shirt is a patented one-piece garment for infants with an opening built in to enable access to a gastric feeding tube



Spencer James

I am currently a senior at Miami Palmetto High School and invented the G-Shirt when I was in fourth grade as a science project. My cousin Jamie has a metabolic disorder called Glycogen Storage Disease, and he required a feeding tube to be fed every 2-3 hours around the clock. I was motivated to create this device to make his life and his parents' lives easier. The G-Shirt would allow his feeding tube to be more easily accessible, especially in the middle of the night so he wouldn't be woken up when he needed to be fed.

Background Information


Glycogen Storage Disease

Glycogen storage disease (GSD) is a group of metabolic disorders caused by enzyme deficiencies affecting either glycogen synthesis, glycogen breakdown or glucose breakdown, typically in muscles or liver cells.

Gastric Feeding Tubes

A gastric feeding tube is a device that is surgically inserted into your stomach through an opening on your abdominal wall. It is used to supply nutrition when you have difficulty eating. Gastric feeding tubes are also known as G-Tubes.

"This is fantastic - as a ped surgeon who is always trying to get to kids' g-tubes I say patent this while you still can!"
