A thin, flexible plastic tube passed through the nose, down the oesophagus, and into the stomach for feeding, hydration, or medication. Nasogastric feeding supports patients who cannot swallow safely or eat enough, such as those recovering from stroke, surgery, or critical illness, delivering liquid nutrition directly to the stomach. Correct placement must be confirmed before each use, since misplacement into the lungs causes serious harm. The tube is less invasive than surgical feeding options and suits short- to medium-term use, though prolonged use can irritate the nose and throat. Dietitians calculate feed regimens to meet individual nutritional needs.
