When patients can no longer eat through their mouth (for example, when they are sedated, in a coma, or have problems swallowing), they will be fed through a tube inserted into their stomach through a feeding tube or ‘stomach tube’. This is called “enteral feeding”. Another possibility if the digestive system is not functional, is to feed the patient through “infusion”. This is called “parenteral feeding”. Food/nutrients are administrated in liquid form, through the catheter, and cover all the patient’s needs.
