Why do you have to give glucose drip intraveinous?

Intravenous (IV) glucose drip is administered directly into a vein, bypassing the digestive system. This method of delivery ensures the rapid and controlled administration of glucose into the bloodstream, making it particularly suitable in certain medical situations:

1. Immediate Energy Source: During critical conditions like severe illness, injury, or surgery, the body may have difficulty digesting and absorbing nutrients from ingested food. IV glucose provides a quick and direct source of energy to fuel the body's vital functions and prevent complications arising from hypoglycemia (low blood sugar).

2. Treatment of Severe Hypoglycemia: In cases of severe hypoglycemia, where blood sugar levels drop dangerously low, oral glucose may not be effective due to impaired absorption. IV glucose administration rapidly raises blood sugar levels, restoring them to a safe range.

3. Fluid and Electrolyte Balance: IV glucose drips can also serve as a source of fluids and electrolytes, helping to maintain hydration and electrolyte balance in individuals who are unable to tolerate or absorb oral fluids, such as those with severe vomiting or diarrhea.

4. Support During Fasting or Prolonged Procedures: During certain medical procedures or examinations that require fasting, IV glucose provides essential energy and prevents complications from prolonged fasting. This may be relevant during procedures like endoscopy, colonoscopy, or certain imaging studies.

5. Nutritional Support: IV glucose may be necessary to provide nutritional support in situations where the digestive system is temporarily unable to function properly, such as in critical illness, severe malnutrition, or conditions requiring bowel rest.

It's important to note that IV glucose administration should be closely monitored by healthcare professionals to avoid potential complications such as hyperglycemia (high blood sugar), fluid overload, or electrolyte imbalances. The specific concentration and rate of IV glucose infusion are adjusted based on the individual's condition, blood sugar levels, and fluid requirements.
