What is the primary indication for the use of insulin?

The primary indication for the use of insulin is to manage blood glucose levels. Insulin is a vital hormone that regulates blood sugar levels in the body, particularly for individuals with diabetes mellitus. In these patients, the body either does not produce sufficient insulin (Type 1 diabetes) or cannot effectively use the insulin it produces (Type 2 diabetes). Administering insulin helps lower blood glucose levels by facilitating the uptake of glucose into the cells, where it can be utilized for energy or stored for future use.

Effective management of blood glucose levels is crucial in preventing both acute and chronic complications associated with diabetes, such as hyperglycemia, hypoglycemia, cardiovascular disease, nerve damage, kidney failure, and vision problems. Understanding the role of insulin in blood glucose regulation is essential for students studying pharmacology and healthcare professionals providing care to diabetic patients.
