Can a nasogastric tube help internal bleeding?

Not necessarily.: An "ng" tube is often placed to help determine where in the GI tract the bleeding source is and how much blood loss there is. It will not stop the bleeding. Gastrointestinal bleeding often stops on its own. If it does not, an endoscopy or surgery may be needed. Sometimes a radiologist can stop the bleeding by plugging (embolization) the bleeding blood vessel.
