- A nasogastric (NG) tube may be needed if your nausea and vomiting is severe. The NG tube is put into your nose and moved down your throat until it reaches your stomach. Liquid, nutrition, or medicine may be given through an NG tube. The tube may instead be attached to suction if healthcare providers need to keep your stomach empty.
