Under what conditions does patient need to take a drip of glucose?

A patient should be given glucose drip when he is dehydrated. Glucose drip is also given when the patient is unable to take his food orally.
Dehydration occurs when water and electrolytes are lost during diarrhea. ‘Drip of Glucose’ can be referred either to Intravenous infusion of Dextrose (which is a biologically active form of Glucose) or to any Intravenous Fluid. As glucose is the necessary substance to provide energy, it should be given as drips until the person is able to recover from illness completely and eat his food without difficulty.
