Glucose solution is widely used in medical settings to provide energy and hydration to patients who cannot take oral fluids or nutrients. It is commonly administered intravenously to treat low blood sugar (hypoglycemia), dehydration, and to support patients during fasting or after surgery. In emergency care, concentrated glucose solutions help rapidly restore blood glucose levels in individuals with severe hypoglycemia. It is also used as a diluent for compatible medications given by IV infusion. In diagnostic procedures, glucose solutions are used in glucose tolerance tests to assess how the body processes sugar, aiding in the diagnosis of diabetes and related conditions. Outside of clinical use, glucose solutions serve as a carbon source in laboratory cultures and in the food industry for fermentation processes and as a sweetener in liquid formulations.
