Used as a source of energy in intravenous feeding for patients who cannot eat or drink, glucose solution helps maintain blood sugar levels during fasting or illness. It is commonly administered in hospitals to treat dehydration, low blood sugar (hypoglycemia), and as part of fluid replacement therapy. In medical settings, it serves as a carrier for intravenous medications. Also used in oral rehydration therapy, it aids in restoring electrolyte balance. In laboratory environments, glucose solution provides energy for cell cultures and supports microbial growth in experiments.
