What role does insulin play in the management of diabetes?

1. Increases blood sugar levels

2. Reduces cholesterol levels

3. Manages blood sugar levels

4. Cures diabetes

The correct answer is: Manages blood sugar levels

Insulin is a crucial hormone in the regulation of blood glucose levels, particularly in individuals with diabetes. Its primary role is to facilitate the uptake of glucose into the cells, allowing the body to use it for energy or store it for future use. When insulin is present, it helps lower the concentration of glucose in the bloodstream, making it a vital component in managing blood sugar levels. In people with diabetes, either the body does not produce enough insulin (as in Type 1 diabetes) or the cells become resistant to its effects (as in Type 2 diabetes). Effective management of diabetes often involves the use of insulin therapy to help maintain stable blood glucose levels, thereby preventing the complications associated with high blood sugar. In contrast, while insulin can have a secondary effect on cholesterol levels, it is not primarily designed to manage cholesterol. Furthermore, insulin does not cure diabetes; it is a management tool to help control the condition. Lastly, insulin directly decreases blood sugar levels rather than increasing them.
