Question

Why insulin not administered orally to diabetic patient?

Answer 1

Explanation:

1. If our body is unable to produce insulin on its own, we must administer insulin intravenously in order to survive.
2. In nature, insulin is a peptide—a brief chain of amino acids.
3. If administered orally, it will enter the stomach and intestines where it will be broken down by the digestive juices' enzymes before mixing with the bloodstream, causing a sharp rise in blood sugar.
4. Insulin is administered by injection to mix inside the bloodstream so that it can reach the target areas.
5. In this manner, the insulin won't degrade before it gets there.
