A nasogastric tube (NG tube) is a flexible plastic tube inserted through the nose, down the esophagus, and into the stomach. It is used for various medical purposes, including providing nutrition to patients who cannot eat by mouth, removing stomach contents, or administering medications. The tube is typically placed by a healthcare professional and can be used for short or long-term treatment. NG tubes come in different sizes and are made of soft, pliable materials to minimize discomfort. They are often secured to the patient's nose and monitored regularly to ensure proper placement and function. Proper care and hygiene are essential to prevent complications such as infections or blockages.
