What is the typical method of administering insulin for diabetes management?

The typical method of administering insulin for diabetes management is subcutaneously. This route is preferred because insulin is a protein that would be broken down and rendered ineffective if taken orally due to the digestive process. When administered subcutaneously, insulin is injected into the fatty tissue just under the skin, allowing for a gradual absorption into the bloodstream. This method enables precise control over blood sugar levels, which is crucial for diabetes management.

Intravenous administration can be used in certain medical settings for rapid control, typically in hospital environments, but it is not the standard method for regular diabetes management. Oral and topical administration are not viable options for insulin due to the reasons mentioned earlier, primarily because insulin must avoid the digestive system to maintain efficacy.
