There are several routes for glucose administration: - Oral Glucose: This is often the first line of treatment for mild hypoglycemia and can be given in the form of glucose tablets, gels, or sugary drinks. - Intravenous Glucose: For more severe hypoglycemia or when oral administration is not possible, intravenous (IV) glucose can be administered. This is usually done in a hospital setting and involves a glucose solution (such as Dextrose 10%, 25%, or 50%) being infused directly into the bloodstream. - Nasogastric Tube: In some cases, glucose can be administered via a nasogastric tube when oral intake is not feasible.
