Gastric suction

Definition

Gastric suction is a procedure to empty the contents of your stomach.

How the Test is Performed

A tube is inserted through your nose or mouth, down the food pipe (esophagus), and into the stomach. Your throat may be numbed with medicine to reduce irritation and gagging caused by the tube.

Stomach contents can be removed using suction right away or after spraying water through the tube.

How to Prepare for the Test

In an emergency, such as when a person has swallowed poison or is vomiting blood, no preparation is needed for gastric suction.

If gastric suction is being done for testing, your health care provider may ask you not to eat overnight or to stop taking certain medicines.

How the Test will Feel

You may feel a gagging sensation as the tube is passed.
