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 vehicle for delivering medications through IV. Athletes and individuals with exhaustion may use oral glucose solutions to quickly restore energy. It is also used in diagnostic procedures, such as glucose tolerance tests for diabetes. In laboratory environments, glucose solutions support cell cultures by providing essential energy for cellular processes.
