A PEG tube, or percutaneous endoscopic gastrostomy tube, is a medical device used to provide nutrition to individuals who cannot eat by mouth. It is inserted through the abdominal wall into the stomach using an endoscopic procedure. This allows for direct delivery of food, fluids, and medications, ensuring that patients receive the necessary nutrients. PEG tubes are often used for patients with conditions such as stroke, neurological disorders, or cancer that impair swallowing. The tube can remain in place for an extended period, making it a practical solution for long-term nutritional support. Regular care and monitoring are essential to prevent complications.
