Nutrition by the intravenous route. It is used in cases where oral intake is not possible or is inadequate. It is administered if the patient is admitted (though in special cases it is performed at home) and will be continued until oral feeding is resumed.
If you receive parenteral nutrition, should know that your blood glucose level may be increased and require insulin administration. This does not mean that you have “become” a diabetic and will need insulin the rest of your life. Once parenteral nutrition is discontinued, it will return to its previous levels.
