What is the primary function of insulin in diabetes management?

The primary function of insulin in diabetes management is to lower blood sugar levels. Insulin is a hormone produced by the pancreas that facilitates the uptake of glucose from the bloodstream into the cells of the body, where it is used for energy. In individuals with diabetes, the body's ability to produce or respond to insulin is impaired, leading to elevated levels of glucose in the blood.

When managing diabetes, administering insulin helps decrease high blood sugar levels by promoting the absorption of glucose, thereby helping to prevent the complications associated with chronic hyperglycemia, such as cardiovascular diseases, kidney damage, and nerve damage. This regulation is crucial for individuals with type 1 diabetes who produce little to no insulin, and can also play a significant role in the management of type 2 diabetes, particularly in cases where other medications are insufficient to control blood glucose levels.

The other options do not align with the fundamental role of insulin. Raising blood sugar levels contradicts the primary function of insulin, while balancing electrolytes and controlling blood pressure are not directly related to insulin's role in glucose metabolism.
