This document provides an introduction to PEG (percutaneous endoscopic gastrostomy) feeding. PEG is a medical procedure where a feeding tube is inserted directly into the stomach through the abdominal wall, allowing for enteral nutrition when oral intake is not adequate. The document outlines what PEG is, the insertion method, benefits of PEG feeding, post-insertion management and care, potential complications, and feeding techniques. PEG is an alternative to open surgical gastrostomy that does not require general anesthesia, using mild sedation instead. PEG tubes can also be extended into the small intestine for feeding.
