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 supply calories in fasting or critically ill patients. In hospitals, it serves as a vehicle for delivering medications through IV infusions. Concentrated glucose solutions are also used in diagnostic procedures, such as glucose tolerance tests, to evaluate insulin response and diagnose diabetes. In addition to clinical uses, glucose solutions are employed in fermentation processes in the food and beverage industry, supporting the growth of microorganisms that produce alcohol, organic acids, or other compounds. It is also used in laboratory settings as a carbon source in cell cultures and microbiological media.
