What is a nasogastric tube, and in what situations is this “stomach tube” useful?

A nasogastric tube is a very thin tube that is inserted into the stomach through the nose and down the throat. This “gastric tube” is used to administer fluids, medications, or nutritional solutions when swallowing is not possible.

In this procedure, a thin plastic tube is inserted through one nostril and, using gentle pressure, guided through the throat and esophagus into the stomach. This creates a direct connection from the outside to the stomach. A disadvantage is that the tube is located in the throat and esophagus, which limits or prevents additional oral food intake. Therefore, a nasogastric tube is only suitable for short-term use (and mostly for patients in intensive care).

For patients with ALS, the goal is long-term nutrition, combining oral feeding (continuing to eat regular meals) with supplemental fluid and calorie intake via a feeding tube. Neither of these goals—long-term tube feeding nor the ability to combine oral nutrition with tube feeding—can be achieved with a nasogastric tube (“stomach tube”); therefore, a PEG tube is generally preferred for ALS.

A nasogastric tube is used in very specific situations, such as when it is necessary to bridge the time until a PEG tube can be placed. In certain palliative care situations, patients may prefer to avoid a long-term PEG tube and instead seek temporary administration of fluids and medications. In such cases, a nasogastric tube can provide assistance and relief.
