Nasogastric Tube
A nasogastric (NG) tube passes through the nose into the stomach to give feed and medicines, or to drain the stomach.
Quick answer
Nasogastric Tube: what it is, why it's done and what happens
A nasogastric tube is a thin, flexible tube passed through a nostril, down the gullet and into the stomach. It can deliver liquid feed, fluids and medicines, or drain stomach contents.
- Why it is done: It is used for short-term feeding when someone cannot safely swallow enough, to give medicines, and to empty the stomach in conditions such as bowel obstruction or after some surgery.
- What happens: The tube is gently passed through the nose while the person swallows, which can feel uncomfortable briefly.
What it is
A nasogastric tube is a thin, flexible tube passed through a nostril, down the gullet and into the stomach. It can deliver liquid feed, fluids and medicines, or drain stomach contents.
Why it is done
It is used for short-term feeding when someone cannot safely swallow enough, to give medicines, and to empty the stomach in conditions such as bowel obstruction or after some surgery.
What happens
The tube is gently passed through the nose while the person swallows, which can feel uncomfortable briefly. Its position in the stomach is carefully checked (often by testing aspirate or an X-ray) before it is used.
Recovery
An NG tube is usually a short-term measure and is removed easily once no longer needed. Longer-term feeding may use a tube placed directly into the stomach (such as a PEG) instead.
Good to know
Risks and things to consider
Risks include discomfort, the tube moving out of place, and — importantly — the tube going into the lung by mistake, which is why position is always checked before use. It suits short-term rather than long-term feeding.

Answers
Nasogastric Tube: frequently asked questions
Why is the tube’s position checked before every feed?
It is vital to confirm the tube is in the stomach and not the lungs, as feeding into the lungs is dangerous. Staff check the position, often by testing fluid drawn back or with an X-ray, before using it.
Is an NG tube used long term?
It is generally used for short-term feeding or draining. If longer-term feeding is needed, a tube placed directly into the stomach through the abdomen, such as a PEG, is usually preferred.
