Insulin is crucial for managing diabetes, particularly for those with type 1 diabetes (DM Type 1), where the pancreas does not produce enough insulin. It is also used in some cases of type 2 diabetes, usually alongside oral medication. Insulin types are classified by their onset and duration of action:

Administration of Insulin
Insulin is administered subcutaneously, meaning it is injected just below the skin. Common injection sites include the abdomen, arms, or legs. Rotating injection sites is recommended to prevent tissue damage in any one area. Insulin should be stored in the refrigerator unless otherwise directed by a healthcare provider.
