What is a primary indication for insulin?

• A. Type 1 diabetes
• B. Type 2 diabetes
• C. Hypertension
• D. Hypoglycemia

Answer: (A)

Insulin is primarily indicated for the management of Type 1 diabetes. In this condition, the body's immune system attacks and destroys the insulin-producing beta cells in the pancreas, leading to little or no insulin production. As insulin is a crucial hormone for regulating blood glucose levels, individuals with Type 1 diabetes require exogenous insulin to manage their blood sugar effectively and prevent acute complications such as diabetic ketoacidosis. While insulin may also be used in Type 2 diabetes, especially in advanced cases or when other oral medications are insufficient, the mainstay treatment for Type 2 often starts with lifestyle modifications and oral hypoglycemics. Hypertension is not treated with insulin, as high blood pressure is managed through other classes of medications. Similarly, hypoglycemia, which is a state of low blood sugar, would not warrant insulin administration; instead, it requires the administration of glucose or carbohydrates to raise blood sugar levels. Thus, the primary indication for insulin is to substitute for the lack of endogenous insulin production in Type 1 diabetes, making it essential for managing this condition.
