A feeding tube is a flexible plastic tube that is inserted into the body to provide nutrition or hydration. It can be placed either through the nose and throat, directly into the stomach or intestines, or even into veins for patients who are unable to eat or drink enough on their own. The tube allows food, liquid nutrients, or medications to be given directly to the patient's body, bypassing the mouth and esophagus if necessary. Feeding tubes can be temporary or permanent, depending on the patient's needs, and are often used in hospitals, nursing homes, or at home for patients who require additional nutrition support.
